Arbitrary Waveform Commands
See also “Arbitrary Waveforms” starting on page 120 in chapter 3.
Arbitrary Waveform Overview
The following is an overview of the steps required to download and
output an arbitrary waveform over the remote interface. The commands
used for arbitrary waveforms are listed on page 236. Refer to chapter 7,
“Tutorial”, for more information on the internal operation of downloading
and outputting an arbitrary waveform.
Note. You can download waveforms of up to 65,536 (64K) points into the
Agilent 33220A from your PC. However, waveforms of greater than
16,384 (16K) points cannot be edited from the Agilent 33220A front panel.
1 Download the waveform points into volatile memory.
You can download from 1 point (a dc signal) to 65,536 (64K) points per
waveform. You can download the points as floating-point values, binary
integer values, or decimal integer values. Use the DATA command to
download floating-point values from -1.0 to +1.0. Use the DATA:DAC
command to download binary integer or decimal integer values from
-8191 to +8191.
To ensure that binary data is downloaded properly, you must select the
order in which the bytes are downloaded using the FORM:BORD command.
2 Select the waveform frequency, amplitude, and offset.
Use the APPLy command or the equivalent FREQ, VOLT, and VOLT:OFFS
commands to select the frequency, amplitude, and offset of the waveform
.
Chapter 6, “Application Programs”, includes an example program
showing how to download an arbitrary waveform into the Agilent
33220A.
