L. Al4 And Al5 Test Connectors - HP 8560A Service Manual

Caution
Use of an active probe, such as an HP 85024A, with another spectrum
analyzer is recommended for troubleshooting the RF circuitry. If an HP
1120A Active Probe is being used with a spectrum analyzer, such as the HP
set the active probe for an ac coupled output or use a dc blocking capacitor
(HP 11240B) bet ween the active probe and the spectrum analyzer input.
Troubleshooting Using the TAM
When using Automatic Fault Isolation, the TAM indicates suspected circuits that need to be
manually checked. Use Table 11-2 to locate the manual procedure.
Table 11-l lists assembly test connectors associated with each Manual Probe Troubleshooting
test. Figure 11-l illustrates the location of A15's test connectors.
