About the Test Set
How the Test Set Is Used
sequences for the EXT Wireless Communication Test Set. Sequence Studio is able to load waveform
traces directly from the test set, so that the analysis intervals in the sequence can be aligned with the
waveform, using an interactive graph display; this method of creating sequences is much more efficient
than typing in numerical values.
Executing Sequences
Sequences are executed by initiating the source list sequencer, the analyzer list sequencer, or both.
The source list sequencer can be initiated (in any measurement mode) by using the [Source], List
Sequencer, Initiate Sequence key, or by sending the :SOURce:LIST:TRIG command.
The analyzer list sequencer can be initiated (in the Sequence Analyzer mode) by using the [Restart] key,
or by sending the :INIT command.
When both list sequencers are used together, initiation of the sequencers must be carefully coordinated. It
is not possible for both sequencers to be initiated absolutely simultaneously. When both are used, the
source list sequencer should always be initiated first. There are two ways to coordinate the sequencers so
that they are initiated in the proper order:
• Enable Meas Setup, Include Source in Sequence. When this selection is made, both of the list
sequencers are initiated automatically, in the correct order, when you use a command or key to
initiate the analyzer sequence (in this case, the source sequence cannot be initiated independently of
the analyzer sequence).
• If “Include Source in Sequence” is disabled, then the source and analyzer must be initiated
independently, and the source must be initiated first.
In addition to the initiating the sequencers, it is also necessary to trigger them. Output and input
triggering for the two sequencers (as defined in the sequences they are executing) must be set up to
coordinate the timing of their operations. Typically, the analyzer list sequencer generates a trigger input
to the source list sequencer, so that the source begins generating a signal once the analyzer is ready to
receive and analyze it.
