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.
