Generating a Simple Arbitrary Waveform

59 Generating Arbitrary Waveforms with the HP E1340A
This program shows how to generate an arbitrary waveform with a single
waveform segment. The example generates a 4096 point ramp. The AFG
stores the waveform segment into segment memory as voltage data points.
The commands are:
1. Reset the AFG -
*RST
The *RST command aborts any waveform output and sets the AFG to
a defined state.
2. Select the Reference Oscillator -
[SOURce:]ROSCillator:SOURce <
This command selects the Reference Oscillator Source (see
" Program Comments" later in this chapter).
3. Set the Waveform Frequency -
[SOURce:]FREQuency[:CW|FIXed] <
This command sets the repetition rate of the waveform. See
Appendix B for the frequency limits.
4. Select the Arbitrary Waveform Function -
[SOURce:]FUNCtion[:SHAPe] USER
This command selects the arbitrary waveform function.
5. Set the Maximum Output Amplitude -
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
This command specifies the maximum output amplitude. The
amplitude must be equal or greater than the maximum voltage value
of the waveform segment. Refer to Appendix B for the amplitude
limits.
