Chapter 1 General Information Introduction This manual contains information required to test, troubleshoot, and repair the Agilent E1364A B-Size VXI Form C Switch. See the Agilent E1364A User’s Manual for additional information. Figure 1-1 shows the E1364A Switch Module. Figure 1-1.
Safety Considerations This product is a Safety Class I instrument that is provided with a protective earth terminal when installed in the mainframe. The mainframe, switch, and all related documentation should be reviewed for familiarization with safety markings and instructions before operation or service. Refer to the WARNINGS on page 6 in this manual for a summary of safety information. Safety information for preventive maintenance, testing, and service follows and is also found throughout this manual.
WARNING USING AUTOTRANSFORMERS. If the mainframe is to be energized via an autotransformer (for voltage reduction) make sure the common terminal is connected to neutral (that is, the grounded side of the main’s supply). CAPACITOR VOLTAGES. Capacitors inside the mainframe may remain charged even when the mainframe has been disconnected from its source of supply. USE PROPER FUSES.
Inspection/Shipping This section contains initial (incoming) inspection and shipping guidelines for the E1364A Switch Module. Initial Inspection WARNING Use the steps in Figure 1-2 as guidelines to perform initial inspection of the switch module. To avoid possible hazardous electrical shock, do not perform electrical tests if there are signs of shipping damage to the shipping container or to the instrument. Figure 1-2.
Shipping Guidelines Follow the steps in Figure 1-3 to return the E1364A Switch Module to an Agilent Technologies Sales and Support Office or Service Center. 1. Prepare the Switch • Remove user wiring from terminal module. • Attach tag to switch that identifies: – Owner – Model Number/Serial Number – Service Required • Place tagged device in approved anti-static bag. 2. Package the Switch • Place packaged switch in shipping carton.
Environment The recommended operating environment for the E1364A Switch Module is: Environment Temperature Humidity Operating 0oC to +55oC <65% relative (0oC to +40oC) Storage and Shipment -40oC to +75oC <65% relative (0oC to +40oC) Switch Description The Agilent E1364A Switch Module is an "instrument" in the slots of a VXIbus mainframe.

Notes 18 General Information Chapter 1
Chapter 2 Verification Tests Introduction The three levels of test procedures described in this chapter are used to verify that the E1364A Switch Module: • is fully functional (Functional Verification) • meets selected testable specifications (Operation Verification) • meets all testable specifications (Performance Verification) Test Conditions and Procedures See Table 1-1 for test equipment requirements. You should complete the Performance Verification tests at least once a year.
Functional Verification The Functional Verification Test for the E1364A switch consists of sending the *IDN? command and checking the response. This test can be used at any time to verify that the switch is connected properly and is responding to basic commands. Procedure 1. Verify that the switch is installed in the mainframe and that the mainframe has passed its power-on test. 2. Send the *IDN? command to the switch module (see example following). 3.
Performance Verification The procedures in this section are used to test the switch module’s electrical performance using the specifications in Appendix A of the E1364A User’s Manual as the performance standards. These tests are suitable for incoming inspection, troubleshooting, and preventive maintenance. Test Fixture A test fixture is required for the following tests.
Figure 2-1(b).
Test 2-1: Closed-Channel Resistance Test The purpose of this test is to verify that all relay contacts meet the closed-channel resistance specification for the switch module. If the closed-channel resistance of any contact is greater than 3.5 Ω, the relay should be replaced. Normally Open Contacts 1. Hardware Connections Figure 2-2. Closed-Channel Resistance (NO channels) 2. Equipment Setup • Set DMM to: 4-wire ohms, autorange. • Send *RST to the switch to open all NO contacts. 3.
Normally Closed Contacts 1. Hardware Connections Figure 2-3. Closed-Channel Resistance (NC Channels) 2. Equipment Setup • Set DMM to: 4-wire ohms, autorange. • Send *RST to the switch. • Send CLOS (@100:115) to the switch to open all NC contacts. 3. Closed-Channel Reading (channel 00) • Send OPEN (@100) to the switch to close channel 00. • Trigger the DMM and record the reading. 4. Open-Channel Reading (channel 00) • Send CLOS (@100) to the switch to open channel 00.
Example: Closed-Channel Resistance Test This example performs the Closed-Channel Resistance Test for all Normally Open and Normally Closed contacts.

Test 2-2: DC Isolation Test This test verifies that sufficient DC isolation exists between various points on the switch module. The DMM used should be capable of measuring up to at least 1 GΩ. If the DMM indicates an overload, record the reading as ">Rmax", where Rmax is the highest resistance that the DMM can measure. If the DMM is a 3458A, for example, the reading should be written as ">1.2 GΩ". Normally Open to Common 1. Hardware Connections Figure 2-4. DC Isolation Test (NO Channels to Common) 2.
Normally Closed to Common 1. Hardware Connections Figure 2-5. DC Isolation Test (NC Channels to Common) 2. Equipment Setup • Set DMM to: 2-wire ohms, 1 GΩ range. • Send *RST to the switch. • Send the CLOS (@100:115) command to the switch to open all NC contacts. 3. DC Isolation Reading • Trigger the DMM and record the reading.
Normally Open to Chassis 1. Hardware Connections Figure 2-6. DC Isolation Test (NO Channels to Chassis) 2. Equipment Setup • Set DMM to: 2-wire ohms, 1 GΩ range. • Send *RST to the switch. • Send the CLOS (@100:115) command to the switch to close all NO contacts. 3. DC Isolation Reading • Trigger the DMM and record the reading.
Normally Closed to Chassis 1. Hardware Connections Figure 2-7. DC Isolation Test (NC Channels to Chassis) 2. Equipment Setup • Set DMM to: 2-wire ohms, 1 GΩ range. • Send *RST to the switch to close all NC contacts. 3. DC Isolation Reading • Trigger the DMM and record the reading.
