Selecting the Amplitude Levels and Output Units
The OUTPUNIT 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
This command aborts any waveform output and selects the 42.9 MHz
reference oscillator source, DDS sample source (that is, trigger start
source), sinusoid function, arm start immediate, 0 V offset, and a 50 Ω
output impedance and output load.
2. Select the Output Units
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude]:UNIT[:VOLTage]
<
units>
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] <amplitude>
command. The output units are only valid for amplitude and not
offsets (volts is assumed for offsets).
3. Set the Amplitude and the Offset
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <amplitude>
[SOURce:]VOLTage[:LEVel][:IMMediate]:OFFSet <
offset>
These commands specify the amplitude and offset. Refer to Table B-4
in Appendix B for the amplitude limits. The maximum value of the
combined amplitude and offset voltages must remain within the 6.025 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.
