Setting the Arm
and Waveform
Cycle Count
The BURST program shows you how to set the number of arms the AFG is
to receive before returning to the Idle state, and how to set the number of
waveform cycles (repetitions) per arm.
The program sets a five cycle burst that occurs each time an external arm is
received.
The steps of this program are:
1. Set the output (burst) frequency
[SOURce:]FREQuency[1][:CW | :FIXed] <frequency>
2. Set the output function
[SOURce:]FUNCtion[:SHAPe] <shape>
3. Set the signal amplitude
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
4. Set the arm source
ARM[:STARt]:LAYer2:SOURce <source>
5. Set the slope of the external arm signal
ARM[:STARt]:LAYer2:SLOPe <edge>
6. Set the arm count
ARM[:STARt]:LAYer2:COUNt <number>
7. Set the number of waveform cycles (burst count)
ARM[:STARt][:LAYer[1]]:COUNt <number>
8. Place the AFG in the wait-for-arm state
