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 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.

1.

Place the network analyzer and Test Set side by side (not stacked) and connect

 

the I/O cable (N4011-21002). See 

Figure 28 on page 3

9

 

for I/O cable picture.

2.

Ensure that the network analyzer is 

not

 in Multiport Mode.

3.

Using the Test Set I/O Data command values to be given in the preceding

 

procedure, you will observe S21 response measurements. 

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’s rear panel.

•

Remove the front panel RF interface cables and reinstall the analyzer’s front panel
jumper cables.

Equipment Required

Gather the equipment and accessories listed below:

•

PNA, PNA-L or PNA-X Network Analyzer

•

Two RF Flex Cables (3.5 mm male)

•

3.5 mm Adapters (female to female)

•

Test Set I/O Cable
