• The test set and associated equipment are connected as shown in Figure 2-9 on page 2-15. This chapter shows you how the network analyzer can be used to manually control the test set. The method presented here is considered a manual one because the user manually enters individual commands on a keyboard connected to the network analyzer. The chapter includes the following sections: • Preparing the Analyzer to Control the Test Set • How to Send a Manual Command • Common Errors in Manual Commands • A List of GPIB Commands • Restoring the Analyzer to its Normal Configuration • Disaster Recovery Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Step 1. Make sure that all connections shown in Figure 2-9 on page 2-15 have been made. Step 2. Make sure that both the PNA Series analyzer and the test set are turned on. Step 3. On the network analyzer, click the System menu, scroll down to Configure, and click SICL/GPIB. See Figure 3-1, “System Menu.” Figure 3-1 System Menu 3-2 Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Step 4. In the SICL/GPIB window, click System Controller and then OK. See Figure 3-2, “SICL/GPIB Window.” Figure 3-2 SICL/GPIB Window Step 5. Locate the Minimize button (“_”) in the top right corner of the window. See the upper right-hand corner of Figure 3-2. See also the magnified view shown in Figure 3-3, “Minimize Window.” If the button is not visible, click on the View menu, then scroll down to Title Bars and click on it. When the Minimize button is visible, minimize the analyzer window by clicking on the button. Figure 3-3 Minimize Window Click on Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Step 6. On the desktop, double-click the Measurement & Automation icon. See Figure 3-4, “PNA DeskTop.” Figure 3-4 PNA DeskTop Step 7. From the Measurement & Automation window, click on the Devices and Interfaces folder to expand the directory. Step 8. Right-click GPIBO (AT-GPIB/TNT), then click Interactive Control. See Figure 3-5, “Interactive Control window.” Figure 3-5 Interactive Control window 3-4 Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Step 9. When the C:\Progam Files\National Instruments\ NI-488.2\ bin\ibic.exe window appears, type ibdev. See Figure 3-6, “User Controller Window.”. Then you will be prompted to: Enter board index: “0” Enter primary address: “12” Enter secondary address: “0” Enter timeout: “0” Enter ‘EOI on last byte’ flag: “0” Enter end-of-string byte/mode: “1” Figure 3-6 User Controller Window Step 10. If you make a mistake, close the window and repeat steps 7, 8, and 9. Step 11. When the prompt ud0: appears in the window, enter ibclr. This command clears the internal bus. When the ud0: prompt is returned after the ibclr command has been issued, you are ready to issue commands to the test set from this window. Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set Preparing the Analyzer to Control the Test Set Step 12. Use the mouse to size and position the PNA Series Network Analyzer window and the command window (C:\Progam Files\National Instruments \NI-488.2\bin\ibic.exe) so that both windows are visible on the network analyzer screen. See Figure 3-7, “Manual Control Window.” Figure 3-7 Manual Control Window 3-6 Agilent Technologies Z5623A Option H48 Using the Network Analyzer to Control the Test Set How to Send a Manual Command How to Send a Manual Command This procedure assumes the following: • The instructions in the previous section (“Preparing the Analyzer to Control the Test Set”) have been performed. • The command window (C:\Program Files\ National Instruments\NI-488.2\bin\ibic.exe) shown at the bottom of Figure 3-7 is visible on the analyzer. Step 1. Select a command from Table 3-2 or Table 3-3. Step 2. Click in the command window once to ensure that it is active. Step 3. Verify that the last line of text appearing in the window is the ud0: prompt with nothing after it. Step 4. Type ibwrt and then press the
