Troubleshooting the Test Set

RF Switching Failures

If the test set’s RF signal functionality is not operating properly, use the following procedure to

aid in isolating the source of problem. The internal RF solid state switches used in this

instrument are biased with the +24 Vdc supply voltage and controlled logic signals coming

from the test set Controller board and Switch Interface board.

RF Switching Path Test

If you suspect an RF signal path problem with the test set and have verified that the problem in

not the front panel RF interface cables, the following procedure will check all of the RF signal

paths through the test set.

• Install the test set I/O cable from the analyzer to the test set rear panel.
• Remove the front panel analyzer/test set RF interface cables and reinstall the analyzer’s

front panel jumper cables.

Equipment Required

• PNA-X Network Analyzer
• Two RF Flex Cables (3.5 mm male/female)
• 3.5 mm Adapters (female to female)
• Test Set I/O Cable

Equipment Setup

1. Turn on the test set and the analyzer.
2.

Preset

the analyzer and set it to

Standalone Mode

.

Select

(Instrument > Setup > External Hardware > Multiport > Multiport Configuration...>

.

In the dialog box select

Restart as a standalone PNA

>

OK

.

3. Confirm the frequency range is set to 10 MHz to 26.5 GHz.
4. Connect the RF cables to the analyzer’s Ports 1 and 2. Connect the cables together using a

3.5 mm adapter.

5. Configure the analyzer to measure S21 and normalize the response trace.
6. Set the analyzer to

Interface Control Mode
