4 Configuring the Switch/Load Unit WA RNING SHOCK HAZARD. Only service-trained personnel who are aware of the hazards involved should install, remove, or configure the Switch/Load Unit or plug-in cards. Before you remove any installed card, disconnect AC power from the mainframe and from other cards that may be connected to the cards. CAUTION STATIC ELECTRICITY. Static electricity is a major cause of component failure.
4 Configuring the Switch/Load Unit • Agilent E6176A 16-Channel Load Cards Install any Agilent E6176A cards next. • Agilent N9377A 16-Channel Load Cards Install any Agilent N9377A cards next. To allow for future expansion, leave an open slot after the last N9377A card. • Agilent E6178B 8-Channel Heavy Duty Load Cards Agilent E6178B 8 channel Heavy Duty cards require 2 slots each. These cards are installed in even slot locations only.
4 Configuring the Switch/Load Unit For example, Figure 4-1 shows the standard locations for matrix and load cards for a system which contains three matrix cards, a custom card, two 24 channel, four 16 channel, one 8 channel, and one 8 channel heavy duty load card. If using this configuration, be sure to leave the slots open between the cards, as shown in the figure.
4 Configuring the Switch/Load Unit Connecting an Additional (Spare) Power Supply Spare Supply pinout is located at Backplane connector J1 lets you add an additional power supply such as a +24 volt power supply for powering higher voltage relays. Figure 4-2 shows the placement and orientation on the backplane for the power supply components. Connector J1 is loaded at the factory. Capacitor C507 is loaded at the factory to minimize high-frequency noise on the supply line.
4 Configuring the Switch/Load Unit Configuring the Power Busses The UUT power supplies attach to the power busses PB1-PB4. Figure 4-4 shows the power bus connectors J801 and J802 located on the Switch/Load Unit backplane PC board for system integrated SLU. These connectors use screw terminations for high current capability. The J801 connectors are bussed together on the PC board providing a common connection for up to three supplies.
Configuring the Switch/Load Unit 4 Example B (available only as a special configuration) shows two isolated power supplies with separate grounds connected to the power bus. This configuration can be used if, for example, one supply requires local sensing, while the other requires remote sensing at the UUT. Figure 4-6 Example B: Isolated Power Supplies PB1 PB2 VBATT PB3 PB4 VUUT For the standalone SLU, users can directly connect to the external connector “DC Power Bus Connection”. See Figure 4-7.
4 Configuring the Switch/Load Unit Setting the UUT Power Supply Remote/Local Sense Jumpers The UUT power supplies can be configured for either remote sense or local sense. In local sense, the voltage across the load equals the power supply voltage less the voltage drop across the cables between the load and power supply. In remote sense, the voltage across the load equals the selected power supply voltage.
Configuring the Switch/Load Unit 4 For Standalone, toggle PB Sense Remote/Local swithes to select either Remote or Local mode. See Figure 4-9. Figure 4-9 PB Sense Remote/Local Interface (Standalone SLU) For Integrated, use Jumper to select the mode on PB Sense Remote/Local. See Figure 4-10.
4 Configuring the Switch/Load Unit Configuring the Current-Sense Jumpers The Switch/Load Unit is shipped from the factory with the current-sense jumpers J2 installed in the BUSSED position forming one continuous current-sense bus along the Switch/Load Unit backplane. These three jumpers have been included so that, if necessary, the existing single current-sense bus can be split up into as many as four independent current-sense busses by changing the jumper location to SPLIT.
Configuring the Switch/Load Unit 4 For system integrated SLU, jumpers are used to select between Bussed/Split, see Figure 4-12. Figure 4-12 ISense Bussed/Split Interface (Integrated SLU) NOTE E6198B Switch/Load Unit User Manual Ensure Load Cards that will be accessed simultaneously for current-sense readings are located in slots that do not share a common current-sense bus.
4 Configuring the Switch/Load Unit Connecting E6198B to the Computer via USB Interface or Parallel Port USB interface is introduced in E6198B, on top of parallel port interface which is available on the older version on SLU. The USB interface connects to the PC controller using a standard USB cable. See Figure 4-13.
4 Configuring the Switch/Load Unit Adding a Second Switch/Load Unit You can add a second Switch/Load Unit to the system as the load and switching requirements increase. Connection to the PC controller can be made to any existing USB port or via an externally powered USB hub. For Standalone SLU, the Frame Select toggle switches, sets the address of each Switch/Load Unit (see Figure 4-14). The toggle switches can be set for any address from zero to seven.
4 Configuring the Switch/Load Unit Load Box Installation Figure 4-15 Load Box installed • Install 4 tinnermans (0590-0804) at the proper locations on the back of the rack. • From the back of the rack, position the load box onto the rails and secure to the rack using 4 spacers (0380-0317) and 4 dress screws (0570-1272). • Spacers are only required for the first loadbox (to clear the door latch). • Check the build list for the number of load boxes (E6198B) required.

Using Load Cards and Loads 5 Figure 5-4 Agilent E6175A 8-Channel Load Card Layout Selecting a Power Supply Configuration Each channel pair connects to the power bus via a Form C SPDT (single-pole, double-throw) relay. This relay has an NO (normally-open) and an NC (normally-closed) terminal. Each NO terminal is connected to a pin on J3, and each NC terminal is connected to a pin on J4. Each pin on J3 or J4 can be connected to any of the four power bus lines on J5 via jumper wires.
5 Using Load Cards and Loads The factory default is to provide two jumper combs, one that ties all the pins on J3 together and one that ties all the pins on J4 together. The NO pins are jumpered to power bus 2, and the NC pins are jumpered to power bus 1. The jumper combs for J3 and J4 can be easily cut to provide bus or pin isolation between the various input/power bus connections.

The location of the components listed in Table 5-2 are silk-screened on the load card's printed circuit board. Installing a current transducer involves both elements of a channel pair. For example, if the LEM module were to be installed across channels 1-2: 1 Remove the 0.

5 Using Load Cards and Loads Selecting and Loading Flyback Protection Coils used as loads may have large flyback voltages which have the potential to damage other electronic components. Generally, the UUTs are equipped with flyback protection, so flyback protection on the load cards is redundant but provides additional back-up protection in case a defective UUT is tested. The system integrator is responsible for ensuring flyback protection devices are installed on the load cards.
Using Load Cards and Loads 5 Figure 5-8 8-Channel Load Card Detail - Flyback Protection Circuit The flyback protection devices should be installed with the positive side towards the UUT. On each of the four channel pairs the high (+) side should be located as shown in the component locator diagram, Figure 5-9.
5 Using Load Cards and Loads Protection Devices MOV (Metal Oxide Varistor), or back-to-back zener diodes are recommended for flyback voltage protection.* Refer to Figure 5-10. Zener Diode, MOV (Metal-Oxide Varistor) or Transzorb® devices mounted at RTx or RTy (2 required per load - 1 at NC and 1 at NO) provide current path for the inductive load flyback. Select the protection device so that it conducts at a voltage higher than the UUT's internal protection.
5 Using Load Cards and Loads Selecting a Load Fuse The load fuses used are IEC 5x20 mm, 5-ampere slow-blow. These fuses may be replaced by larger fuses if required by your equipment, but not to exceed 8 amperes. In any event, the maximum fuse rating must not exceed an I2T value of 102-126.* Sample Load Configurations Four sets of tandem loads, each set sharing a current-sense resistor, may be mounted on the Agilent E6175A Load Card. You may need to drill holes in the sheet metal to attach the loads.

Using Load Cards and Loads 5 Setting up a Bridge Configuration In the bridge configuration the power bus power supplies are not used. The power for the bridge is supplied by the module; the connection to the UUT power supply is effectively bypassed. See Figure 5-12. Figure 5-12 Bridge Configuration for Channels 7 and 8 on 8-Channel Load Card Use the following table to determine the appropriate pins on J6 and J7 to jumper to create a bridge circuit on the indicated channels.
5 Using Load Cards and Loads Bridge Circuit on: Jumper Pins: Channels 1 and 2 J6, 1 and 2 Channels 3 and 4 J6, 3 and 4 Channels 5 and 6 J7, 1 and 2 Channels 7 and 8 J7, 3 and 4 Bridge load flyback protection may be installed to power busses as a normal load if jumpered, or channel to channel by installing protection devices across the bridged channels. Connecting Loads Loads are mounted on the Agilent E6175A’s sheet-metal mounting area.
5 Using Load Cards and Loads Load Wiring Figure 5-14 is a simplified schematic and P1 connector pinout showing how loads are connected to P1. Load 1 connects to Channel 1 (P1 row 16) and Power 1 (P1 row 15); Load 2 connects to Channel 2 (P1 row 14) and Power 2 (P1 row 13), and so on. To prevent premature pin failure from excessive current flow, when connecting high-current (>3 amp) loads to P1, wire across all three pins in each row (see Figure 5-15 on page 22).
5 Using Load Cards and Loads Current Sharing Notice in the wiring schematic (Figure 5-14) that pins A, C and E in each row of J1 are connected together on the PC board. When connecting high-current (>3 amp) loads, wire across all three pins in each row of P1 (see Figure 5-15). This ensures current sharing across all pins and prevents premature pin failure from excessive current flow.
5 Using Load Cards and Loads UUT Connections When configured as part of a standard Agilent system, P2 of the load card is typically connected via cables to a mass interconnect panel. User connections to the UUT are then made from the mass interconnect panel. Refer to the appropriate mass interconnect wiring guide for connection details. You can also make connections directly to P2. Figure 5-16 is a P2 connector pinout showing the details. Each even-numbered row of P2 represents a single load card channel.

5 Using Load Cards and Loads CAUTION The load cards are designed for a maximum of 500 Vpeak flyback voltage. Operating the load cards without flyback protection installed on the appropriate channels, or with flyback voltages in excess of 500 Vpeak, may results in damage to the load card or SLU. The Agilent E6176A Load Card comes with provisions for user-installed flyback voltage protection. Figure 5-40 is a detail of the first two channels on the component locator diagram of the load card.

This ensures current sharing across all pins and prevents premature pin failure from excessive current flow.
5 Using Load Cards and Loads External Load Mounting Options Loads typically consist of “real” devices (injectors, actuators, etc.) that cannot be mounted on the load card. If cable resistance is a significant factor (such as for low form-factor or low-value resistive loads), one solution is to mount the loads on a metal plate that fits into the SLU slots adjacent to the load card (Figure 5-25).

5 Using Load Cards and Loads Note that the main power bus as well as each individual channel bus is rated for 30 Amps continuous. Thus you can run 30 Amps per channel for all 8 channels only if they are wired in a bridge configuration or the current through the power supply bus (PSbus) does not exceed 30Amps. CAUTION It is possible to close more than one channel at a time.
5 Using Load Cards and Loads Current Monitor Each channel on the Agilent E6178 uses a LEM* model LA 55-TP Current Transducers with a 75 Ω 0.01%, 0.3W low TC (±2.5 ppm/°C) resistor for sensing the current through each channel. The sense relays are switched independently from the channel load relays. The LEM current transducer module has a current gain of 1000:1 (primary to secondary, i.e., for a 1 amp primary current the secondary current is 1mA).
5 Using Load Cards and Loads CAUTION The load cards are designed for a maximum of 500 Vpeak flyback voltage. Operating the load cards without flyback protection installed on the appropriate channels, or with flyback voltages in excess of 500 Vpeak, may results in damage to the load card or SLU.

5 Using Load Cards and Loads * The I2T figure is an industry standard term. For example, if a fuse with a rating of I2T = 100 experiences a current surge of 10A, it can maintain that current for 1 second before its capacity is exceeded. (10A * 10A * 1 Second = 100) Selecting and Loading Flyback Protection Coils used as loads may have large flyback voltages, which have the potential to damage other electronic components.

RT502 connects input line J4-J7, and RT501 connects alternate input line J8-J11, to the output of Load1. When a voltage spike occurs on the UUT that exceeds the rating on the flyback device, the device clamps the surge voltage to the device’s predetermined value. The flyback protection is installed similarly on each input line.

5 Using Load Cards and Loads Selecting a Power Supply Configuration Each channel connects to the power bus via a Form C SPDT (single-pole, double-throw) relay. This relay has a NO (normally-open) and a NC (normally-closed) terminal. Each NO terminal is connected to a pin on J808–J813, and each NC terminal is connected to a pin on J802–J807. Each pin on J802–J813 can be connected to any of the four power busses on J801 via jumper wires (Figure 5-54).
5 Using Load Cards and Loads Connecting Loads Loads are mounted on the Agilent N9378A’s mezzanine cards (Figure 5-56). Up to four loads per channel can fit on each mezzanine card. • The mezzanine cards plug into the 1-3 upper and 1-3 lower positions on the load card. The channel number depends on the placement of the mezzanine card. See Figure 5-54 for details of card placement and channel locations. You can also read the channel assignments from the printing on the front or back of the load card.

Agilent TS-5000 E6198B Switch/Load Unit User Manual 6 Using the Pin Matrix Cards Using the 32-Pin Matrix Cards 6-2 Using the 64-Pin Matrix Cards 6-16 This chapter describes how to configure and use the Agilent Pin Matrix Cards which slots into the Switch/Load unit. Register descriptions for these cards are located in Appendix B of this manual. NOTE This chapter describes using the Agilent 8792A or 8782A as the Instrument Matrix.
6 Using the Pin Matrix Cards Using the 32-Pin Matrix Cards Conceptual Overview Both the Agilent E8792A and E8793A 32-Pin Matrix Modules contain a 32 x 4 Measurement Matrix for switching signals to and from the Analog Bus. The Agilent E8792A also contains a 16 x 5 Instrument Matrix that connects external measuring instruments to the Analog Bus. Figure 6-1 is a simplified block diagram showing how the Agilent E8792A and E8793A are typically used together in a system.
Using the Pin Matrix Cards 6 • Automatic disconnecting of column relays for minimal loading of the Analog Bus, • A single control bit can open all relays (OAR), • Auxiliary or direct row access relays on each row, • Independently switchable series resistance protection on each column. Detailed Block Diagram Descriptions Figure 6-2 is a detailed block diagram of the Agilent E8792A 32-Pin Matrix Card and Figure 6-3 is a detailed block diagram of the Agilent E8793A 32-Pin Matrix Card.
6 Using the Pin Matrix Cards Disconnect Relays automatically disconnect unused columns to minimize capacitive loading effects from the Analog Bus. This makes it possible to expand the system without degrading the accuracy of measurements. Besides the 32 x 4 matrix of relays, there are switched auxiliary I/O lines (AUX1 through AUX32) connected to each of the 32 rows. These ports are for digital I/O operations or other user-defined applications.

6 Using the Pin Matrix Cards Relay Timer The Relay Timer indicates whether or not the last change to a relay's state (opening or closing the relay) is complete. The timer starts or restarts when a command to change a relay's state is received. The timer stops when it times out after an interval sufficiently long for a relay to change state. If the relay timer's status is “busy,” as reported by bit 7 of the Status Register (see Appendix B), relays may not yet be in the desired state.
6 Using the Pin Matrix Cards Protection Bypass Each of the four columns has a 200 ohm protection resistor connected in series which protects the relays by limiting the maximum current through the column. Some measurements (such as 2-wire resistance) may require bypassing (shorting across) the protection resistor to remove its effects. The default state is to have the protection bypass relays open, which means the series protection resistors are in circuit.
Using the Pin Matrix Cards 6 WA RNING SHOCK HAZARD. Only service-trained personnel who are aware of the hazards involved should install, remove, or configure the Switch/Load Unit or plug-in cards. Before you remove any installed card, disconnect AC power from the mainframe and from other cards that may be connected to the cards. CAUTION STATIC ELECTRICITY. Static electricity is a major cause of component failure.

The Analog Bus connection cables require that all 32-Pin Matrix Cards be in adjacent slots (so the cables will reach). Figure 6-10 shows a typical installation.
6 Using the Pin Matrix Cards Using the 64-Pin Matrix Cards Conceptual Overview The Agilent E8782A Pin Matrix contains 40 x 4 Measurement Matrix for switching signals to and from the Analog Bus. It also contains a 24 x 5 Instrument Matrix that connects external measuring instruments to the Analog Bus. The E8783A Pin Matrix Modules contain only a 64 x 4 Measurement Matrix for switching signals to and from the Analog Bus.

Agilent TS-5000 E6198B Switch/Load Unit User Manual C Repair Information Support Strategy C-2 Locating Load Card Components C-2 Agilent Technologies C-1
C Repair Information Support Strategy Rebuilt exchange assemblies are available for many Agilent VXI modules. However, there are no exchange assemblies available for the load cards. If a load card fails, you have two choices: purchase a new load card or troubleshoot the problem and repair it. If the problem is a relay and you can determine which relay is defective, you can repair the module. The relays are through-hole technology and easy to replace.

Agilent TS-5000 E6198B Switch/Load Unit User Manual Glossary Of Terms Agilent Technologies G-1
G Glossary Of Terms • Adjustment An adjustment is an action performed in the field to modify an instrument's response to some input. It can usually be performed by the user on-site. • Calibration A standardized maintenance procedure designed to ensure system accuracy. In this manual it refers to removing those items that require calibration - the DVM and the Frequency Counter - and shipping them to an Agilent bench site for calibration.
G Glossary Of Terms • Glitch An unexpected or unplanned event or occurrence. Abrupt termination of tests is usually due to a software glitch. • GP Acronym for General Purpose. The relays on the E6177A 24-Channel Medium Current Load card can be configured as GP relays. • Hardware Configuration The physical and functional arrangement of the system components with respect to each other. Refers to the relative placement of modules load cards in the E6185A Switch/Load Unit.
G Glossary Of Terms • Load Card A C-sized card designed to fit in the Switch/Load Unit that provides switching for the various loads, and provisions for either internal load mounting, or connections for external load mounting. Load cards provide a two level card ID; card type, and load configuration ID. • Load Switching A load that can be switched in or out of a power supply circuit on command. • Module As used in this manual, specifically refers to a VXlbus-compatible module instrument.
G Glossary Of Terms For example: If the UUT requires precisely 12 Vdc applied to it, and there is a 0.5 Vdc drop between the power supply and the UUT due to system and cable losses, setting the voltage sense to remote and thereby monitoring the power supply output at the UUT will compensate for the voltage drops between the power supply and the UUT. • Rs Source resistance.
