Service Information

RF Switching Failures

Typical failures may be the loss of RF switch control failure or a non RF failure as outlined in the prior
section. The internal RF switches used in this instrument are controlled by the +24 Vdc from the Switch
Driver board.

1. Confirm that the network analyzer and test set are properly connected using the test set I/O cable

(N4011-21002). See

Figure 11 on page 17

2. Using Multiport Mode (Option 551), verify that the network analyzer firmware is correct, and that the

test set file is loaded into the network analyzer. Refer to

“Network Analyzer Requirements” on page 4

3. Using the I/O command values, confirm that the correct address and data values are used. Refer to

“Address and Data Values” on page 38

4. Follow the

“Non-RF Failures” on page 59

procedure (if not already done so).

5. Front Panel R and S indicator LED Check.

a. Confirm that the test set Controller Board Status LED’s are On. Refer to

Figure 48 on page 60

. If the

LED’s are Off remove the Switch Driver board, if the LED’s are remain Off replace the Controller
board.

b. If the Status LED’s are On and the front panel Active LED is On, suspect the front panel LED board or

the ribbon cable (replace as needed).

6. Confirm the DC +24 Vdc switch drive voltages on the Switch Driver Bd by connecting a voltmeter to one

of the Jxx locations as shown in

Figure 49 on page 61

. Do not disconnect the RF Switch connector, this

will keep the switch in place as a load for the following voltage measurement.
