Selecting The Amplitude Levels And Output Units - HP E1340A User Manual

Selecting the Amplitude Levels and Output Units

Chapter 2
This program shows how to set the output amplitude using the VPP (volts
peak-to-peak) output unit. The commands are:
1. Reset the AFG -
*RST
The *RST command aborts any waveform output, selects the sinusoid
function, selects the 42.9 MHz reference oscillator source, arm start
immediate, 0 V offset, and 0 V output.
2. Select the Output Units -
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]:UNIT:VOLTage
This command selects the following output units:
V - Volts
VPK - Volts peak
VPP - Volts peak-to-peak
VRMS - Volts rms
W - Watts
DBM|DBMW - dB referenced to 1 milliwatt
These units are assumed only if no other units are specified in the
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
command. The output units are only valid for amplitude and not
offsets (volts is required for offsets).
3. Set the Amplitude and the Offset -
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
[SOURce:]VOLTage[:LEVel][:IMMediate]:OFFSet <
These commands specify the amplitude and offset. Refer to
Appendix B for the amplitude limits. The maximum value of the
combined amplitude and offset voltages must remain within the
7 V limit.
4. Initiate the Waveform -
INITiate[:IMMediate]
This command generates an immediate output with the arm source
set to IMMediate . Refer to Chapter 5 for triggering information.
