Controlling Multiple Test Sets
Because the HP 85105A has multiple test set switching (Option 001) as
standard, it can control one set of HP 85104A mm-wave test set modules and
one coaxial test set without the need for external switches or instruments. If
it is necessary to control more than one coaxial test set, install Option 001 in
each test set. When installed, the following procedures may be used.
The HP 851X Series Option 001 test sets allow an HP 8510 to alternately
control up to three additional coaxial test sets (Figure on page 6-14),
allowing for a total of four test sets in all. The HP 85105A must be the first
test set in the series. While a measurement is proceeding on test set number
1, which is equipped with Option 001, test device connection may be
completed on test set number 2, which does not need to be equipped with
Option 001 (unless another test set is to be connected). When the
measurement on test set number 1 is completed, then the HP 8510 can
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 connects to the HP 8510.
Option 001 adds a set of IF switches, control switches, and the J10 TEST
SET INTERCONNECT connector. This allows the selection of 20 MHz test
set IF signals. As shown in Figure on page 6-14, test set number 1 can apply
its IF to the HP 8510 or it can switch to pass the IF from test set number 2
through the J10 TEST SET INTERCONNECT to the HP 8510.
