Troubleshooting the Test Set

Non-RF Failures

Non RF failures are; Power Supply, Fans, Control Lines, Status LEDs or Interface not operating.

Refer to

Figure 5

on page 6

Verify that the front panel Power Switch is operational.The front panel Active LED will be

off

unless the test set interface cable is connected and the test set is addressed by the network

analyzer.

Turn on the Standby Switch.

The rear panel, Deck and Internal power supply fans should be operational. If not continue

with

step 4

AC Line voltage checks (remove AC power from the instrument).

Ensure the proper AC Line voltage is present at the instrument line cord.

Remove the AC power cord from the instrument. Verify the instrument AC Line Module

fuse (2119-0709) and replace if necessary. Refer to

Figure 6 on page 13

Verify the Internal AC lines fuse (2110-0342). Remove the instrument bottom cover. Near

the rear panel are two fuse holders, verify the fuses and replace if necessary. See

Figure

on page 7

Internal DC Power checks.

Set the front panel switch to the Standby position. No fans or indicator lights should be

operational.

Remove the top cover.

Set the Standby switch to the

position. Both the rear panel and internal power supply

fans should be operational. Verify that the DC indicator LEDs are

as shown in
