Setting The Arm And Waveform Cycle Count - HP E1340A User Manual

Setting the Arm
and Waveform
Cycle Count
99 HP E1340A Arming and Marker Outputs
The following 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 the AFG receives
an external arm. There will be about a 50 msec delay between a transistion
on the "Aux In" connector and the output switching.
The steps of this program are:
1. Set the Output (Burst) Frequency -
[SOURce:]FREQuency[:CW|:FIXed] <
2. Set the Output Function -
[SOURce:]FUNCtion[:SHAPe] <
3. Set the Signal Amplitude -
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
4. Set the Arm Source -
ARM[:STARt]:LAYer2:SOURce <
5. Set the Edge of the External Arm Signal -
ARM[:STARt]:LAYer2:SLOPe <
6. Set the Arm Count -
ARM[:STARt]:LAYer2:COUNt <
7. Set the Number of Waveform Cycles (Burst Count) -
ARM[:STARt][:LAYer[1]]:COUNt <
8. Place the AFG in the Wait-for-arm State -
