HP 8517B S-Parameter Test Set Manual 3-3
Controlling Multiple Test Sets
HP 851X Series, Option 001 test sets allow an HP 8510C to alternately
control up to four test sets connected to it. For example:
•
While a measurement is underway on test set number 1 (equipped with
Option 001), a test device can be connected to test set number 2 (which
does not need Option 001).
•
When the measurement on test set number 1 is complete, the HP 8510C
can then control test set number 2.
In a standard test set, the 20 MHz IF and control signals are applied directly
to J11 TEST SET INTERCONNECT, which is attached to the HP 8510C.
Option 001 adds a set of IF switches, control switches, and the J10 TEST
SET INTERCONNECT attachment. This configuration allows the selection
of the 20 MHz test set IF signal.
As shown in Figure 3-3 on page 3-4, test set number 1 can:
•
apply its IF signal to the HP 8510C, or it can
•
switch to pass the IF signal from test set number 2, through J10 TEST
SET INTERCONNECT, and into the HP 8510C.
