Generating Zero Crossing Marker Pulses - HP E1340A User Manual

Generating Zero
Crossing Marker
Pulses
Chapter 5
SWEep
This source outputs a marker pulse on the last point of a frequency sweep.
Set the output polarity either to
[SOURce:]MARKer:POLarity
This program outputs a marker pulse whenever the waveform crosses
through zero. The program generates an arbitrary waveform using two
different waveform segments. One waveform segment generates a 1 kHz, 5
V sine wave. The other one generates a 1 kHz, 5 Vpeak triangle.
The commands are:
1. Reset the AFG -
*RST
2. Setup the AFG for an Arbitrary Waveform Output -
[SOURce:]FREQuency[:CW|FIXed] <
[SOURce:]FUNCtion[:SHAPe] USER
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
3. Select the Marker Source -
[SOURce:]MARKer:FEED <
4. Select the Marker Pulse Polarity -
[SOURce:]MARKer:POLarity <
5. Generate and Store the First Waveform Segment -
[SOURce:]LIST[:SEGMent]:SELect A
[SOURce:]LIST[:SEGMent]:VOLTage <
6. Generate and Store the Second Waveform Segment -
[SOURce:]LIST[:SEGMent]:SELect B
[SOURce:]LIST[:SEGMent]:VOLTage <
7. Generate the Output -
[SOURce:]FUNCtion:USER AB
INITiate[:IMMediate]
