Coordinating the Sequencers
Include Source in Sequence is enabled
When Meas Setup, Include Source in Sequence is enabled, the source cannot be initiated
independently. It is initiated automatically, as described below.
Case 1: Test starts when RF is received by the test set
NOTE Whenever “Include Source in Sequence” is enabled, it is recommended to set the analyzer
list sequencer to Single mode, by pressing the
Single key or by sending the
:INIT:CONT OFF command, to avoid timing problems which could occur in
Continuous mode.
Step 1. Set the Step Trigger parameter of the first step in the source sequence to INTernal (the input
trigger will come from the analyzer list sequencer).
Step 2. Set the Input Trigger parameter of the first acquisition in the analyzer sequence to VIDeo (an
RF burst, to be received from the DUT, triggers the analyzer list sequencer).
Step 3. Set the Output Trigger parameter of the first acquisition in the analyzer sequence to INTernal
(the output trigger will be provided to the source list sequencer).
Step 4. Initiate the analyzer list sequencer, using the
Restart key, or by sending the :INIT
command. This initiates the source list sequencer, and arms it to begin running as soon as it
receives the input trigger. Then the analyzer list sequencer is initiated, and armed to begin
running as soon as it is triggered by the DUT’s RF burst. The sequence is executed one time.
