Keysight E5092A ENA Series Configurable Multiport Test Set 153
Troubleshooting
E5092A Setting Troubleshooting
Check control lines setting
The E5092A can control the output from the control line (Figure 3-5) of the
E5092A and control the DUT (for example, switching the frequency band of the
front end module).
Step 1. Short between the pin 12 - 13 and the pin 14 - 15.
Step 2. Press - Multiport Test Set Setup to display the Multiport Test Set
Setup menu.
Step 3. Press Test Set 1 and then select the ID of the E5092A The ID is set with the bit
switch on the real panel of the E5092A.
Step 4. Press Control Lines from group A until group D to the setting menu of the DUT
control line.
Step 5. Use the corresponding softkey to set the control line of the E5092A.
Step 6. Measure the DC voltages of the control lines using a voltmeter with a small
probe. If High is set for each control line, the voltage of the control line is the
same value as the output voltage of the pin 12. If Low is set for each control
line, the voltage of the control line is the same value as the output voltage of
the pin 15.
• If any of the voltages of the control lines are not the same voltages as the
pin 12 or pin 15, the A3 board is suspect.
• If all the voltages of the control lines are good, the A3 board is verified.
