Making Operational Checks

To check the operation of multiple test-set configurations, do the following:

1.Connect a device with a known response to test set number 1. Press the following HP 8510C front-panel keys:

INSTRUMENT STATE [LOCAL]

AUXILIARY MENUS [SYSTEM]

{HP-IB ADDRESSES}

{TEST SET}

2.When the message TEST SET HP-IB ADDRESS appears, enter [20], the address of test set number 1, then press [x1]. The measurement trace from test-set number 1 should display.

3.Store the trace in memory by pressing the following keys:

MENU [DISPLAY]

{DATA AND MEMORIES}

{DATA --> MEMORY n}

DISPLAY: {DATA and MEMORY]

4.Next, enter the HP-IB address of test set number 2, followed by [x1], then re-enter the address of test set number 1 followed by [x1].

5.Repeat the above procedure for each of the other test sets in the system.

Observe any difference in the response between the stored trace and the results trace by switching back and forth between the test sets.

Any differences in data that you suspect are due to the IF switch (Option

001)or to RF switching, must be checked out. Refer to Chapter 5, “Troubleshooting the Test Set” in this manual.
