5 Performance Verification This chapter contains the following sections: • Setting Test Limits • Test Strategy — Insertion Loss — Return Loss — Crosstalk • Setting Up Limit Testing — Limit Testing for Insertion Loss — Limit Testing for Return Loss (Port Active) — Limit Testing for Return Loss (Port Off) — Limit Testing for Crosstalk • Verifying Return Loss and Insertion Loss Specifications • Verifying Crosstalk Specs Agilent Technologies Z5623A Option H48 5 -1
Performance Verification Setting Test Limits Setting Test Limits A test limit is the pass/fail criterion for a measurement. A test limit can be either a maximum limit or a minimum limit. With a maximum limit, the measurement must not go above the limit in order for the Device Under Test (DUT) to pass. With a minimum limit, the measurement must not go below the limit in order for the DUT to pass.
Performance Verification Setting Test Limits Applying Equation 5-1 to the uncertainties listed in Table 5-1 and to the guaranteed specifications listed in Table 1-1 on page 1-4, we obtain the test limits in Table 5-2: Table 5-2 Derivation of Test Limits for Performance Verification of Test Set Parameter Specification Measurement Uncertainty Test Limit Crosstalka,b 1) –110 dBc 2) –105 dBd 3) –95 dBe 4) –90 dBf 1) 5 dBc 2) 5 dBd 3) 5 dBe 4) 7 dBf 1) –115 dBc 2) –110 dBd 3) –100 dBe 4) –97 dBf Return
Performance Verification Test Strategy Test Strategy The overall test strategy of this chapter is to verify each guaranteed specification by means of a limit test that is stored and recalled on the network analyzer. This strategy minimizes the number of cable connections and the amount of time required to complete the performance verification. It also minimizes the likelihood of operator error.
Performance Verification Test Strategy Insertion Loss For this measurement, Port 1 of the network analyzer will be connected to one of the test ports of the test set, and Port 2 of the network analyzer will be connected either to the Reflection port or to the Transmission port of the test set. By definition, Insertion Loss = − S21 where Insertion Loss and S21 are both in units of dB. The network analyzer will be configured to measure S21.
Performance Verification Test Strategy Return loss is specified for two different conditions: • Test port active (this means that the test port is internally connected either to the Reflection port or to the Transmission port) • Test port off (this means that the test port is internally connected to a 50-ohm termination) Return loss is specified for the test ports, but not for the Reflection and Transmission ports.
Performance Verification Setting Up Limit Testing Setting Up Limit Testing In this section, you will create the limit test files described in “Test Strategy” on page 5-4. As you work through this section, record the names of the files you create in Table 5-3.

Measuring Multiport Devices Calibrating the Test System Calibrating the Test System After the test set has warmed up for at least two hours, you must calibrate the instrument before making any measurements. To determine the type of calibration appropriate for the measurements you will be making, refer to the PNA Series Network Analyzers User Guide, part number E8356-90001. You will need to calibrate each measurement path separately and store the calibration as an instrument state in the network analyzer.

7 Advanced Topics This chapter contains the following sections: • Using an External Computer to Control the Test Set • Using the Control Lines Connector Agilent Technologies Z5623A Option H48 7 -1
Advanced Topics Using an External Computer to Control the Test Set Using an External Computer to Control the Test Set Chapters 3 through 6 assume that the network analyzer is being used to control the test set. If desired, an external computer can be used instead. In order to do this, a GPIB cable needs to be connected between the computer and the network analyzer. There is no need to connect a GPIB cable between the test set and the network analyzer in this case.
Advanced Topics Using an External Computer to Control the Test Set Box Identification To read the Box Identification, first query the test set for its ID, then read back the ID from the test set. For example, if the GPIB address of the test set is 12, send the following commands: OUTPUT 712;"id?" ENTER 712;Box_id$ Switch Count The Switch Count is the number of times a switch has been operated. To read the Switch Count for a particular switch, first query the switch and then read back the count.

Advanced Topics Using an External Computer to Control the Test Set Using National Instruments VISA If you are using National Instruments VISA, be sure to set the following variables as follows: VI_ATTR_SEND_END = VI_FALSE ‘ This specifies whether to assert END during the transfer of the last byte of the buffer VI_ATTR_TERMCHAR = 0x0A ‘ This is the termination character. When the termination character is read and VI_ATTR_TERMCHAR_EN is enabled during a read operation, the read operation terminates.
Advanced Topics Using the Control Lines Connector Using the Control Lines Connector The Control Lines connector allows the test set to control other equipment. See Figure 7-1, “Control Lines,” on page 7-7 for a diagram of the connector. The diagram identifies the ground pin and the pin that is associated with each of the five control lines (C1 through C5). (Notice that the connector has three unused pins.) The connector is driven by open-collector output drivers within the test set.
Advanced Topics Using the Control Lines Connector Figure 7-1 Control Lines C3 C2 C4 C1 C5 5 1 9 6 Ground Suggested External Circuitry Figure 7-2 shows one possible set of external circuitry for use with the Control Lines connector. The integrated circuit (IC) shown in the figure is a quad single-pole-single-throw (SPST) CMOS analog switch (Temic/Siliconix Part No. DG413). The IC contains two normally open and two normally closed switches.

Advanced Topics Using the Control Lines Connector The DUT may require a control voltage that is different from any of the existing power supply voltages. Rather than adding another power supply, a circuit such as the one shown in Figure 7-3 can be used to derive the needed voltage from one of the existing power supply outputs. The IC shown in the figure is a 3-Terminal Adjustable Voltage Regulator (National Semiconductor Part No. LM317). It can supply a maximum output current of 1.

8 Service This chapter contains the following sections: • Adjustments • Theory of Operation • Troubleshooting • List of Replaceable Parts Agilent Technologies Z5623A Option H48 8 -1
Service Adjustments Adjustments There are no adjustments for the test set.
Service Theory of Operation Theory of Operation The theory of operation begins with a general description of the test set. This is followed by more detailed operating theory. The operation of each group is described briefly, to the assembly level only. Detailed component-level circuit theory is not provided. System Theory Refer to Figure 8-1 on page 8-2. The test set consists of three main components: a power supply, front panel display, and main switch board.
Service Theory of Operation A2 Controller and A3 Switch Driver Board Theory The mother and daughter boards provide the bias for the switching paths for the various ports to the Reflection or Transmission ports. The front panel display contains an LCD that indicates the switched ports. A particular test port (1 through 8) can be in one of three states.
Service Troubleshooting Troubleshooting This section contains procedures for troubleshooting the test set to assembly level only. These procedures should enable you to determine whether the power supply, front panel, or main switch board needs replacing. Refer to the system block diagram (Figure 8-1 on page 8-2) as an aid in troubleshooting. General Troubleshooting Notes WARNING Always turn the instrument power off before removing or installing an assembly.
Service Troubleshooting Troubleshooting the Front Panel Board Turn the instrument power on and check the following: • Check the condition of each of the switching paths by issuing commands to switch each of the paths to either the transmission or reflection path. Ensure that the LCD indicates the appropriate path. • If the LCD indicates a wrong path, the problem can lie with either the front panel board or the main switch board. Measure the RF path to determine where the problem is.
Service List of Replaceable Parts List of Replaceable Parts The following table contains the list of replaceable parts for the test set.
