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 200. Refer to chapter 7,
"Tutorial", for more information on the internal operation of downloading
and outputting an arbitrary waveform.
Chapter 6, "Application Programs", contains example programs which
show the use of arbitrary waveforms. You may find it useful to refer to
the programs after reading the following section in this chapter.
1 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.
2 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
-2047 to +2047.
To ensure that binary data is downloaded properly, you must select the
order in which the bytes are downloaded using the FORM:BORD command.
