Controlling the Test Set
Test Set Control Commands
The Test Set has predefine
d
sequence command sets
(SCPI)
defined at the
factory and stored in the non-volatile memory of the controller module
(34945EXT)
. If the specified sequence name is not currently stored in the
memory, due to corrupted program or
from accidental deletion
, an error will
be generated. Refer to the Service section of this manual for instructions to
remedy this issue.

Measurement Setup Example
With the following sequence commands, "a2p5" and "b2p10", the Test Set will
position the internal RF switches to create the signal paths needed to
measure the DUT shown in
. All unselected front panel ports will be
terminated by an internal RF switch 50 Ohm load.
In this example
,
we will configure the system to make an S21 measurement.
Network Analyzer Port 1 is the source output port and Port 2 is the receiver
port.
Command: ROUT:SEQ:TRIG a2p5; b2p10
" a2p5", will create a signal path from A Port 2 to Test Port 5.
" b2p10", will create a signal path from B Port 2 to Test Port 10.
