6-12. Pads in Tracking Generator Input Path Test
This test checks the circuits in the signal path shown in Figure 6-4. If the previous tests have
been performed successfully, the only circuits being tested are the Tracking Generator Input
Pads, and relays K3, 4, 5, and 7. A signal is input to the Tracking Generator Input of the
^hp; 35601A from an -hp- 332SA opt 001. The OUTPUT to 358SA is measured with an -hp-
3455A voltmeter. The program notes the voltmeter 'readiagfif the reading is outside the
specified limits, the user is given the option of retesting. The program prints the final results
of the test.

With the High Frequency Menu displayed, press SFK K4 to irul
itialization, follow the instructions displayed on the computer.
What if the Test Fails?
Assuming that the previous tests have passed, and that the equipment is properly connected,
one of the input pads or relays K3, 4, 5, or 7 is probably at fault. Refer to Service Group 2
for schematics, component locators, and circuit descriptions. The "SWITCH" subprogram
can be used to isolate the cause of the failure to one of the relays or pads.
