Generating Built-In Arbitrary Waveforms

73 Generating Arbitrary Waveforms with the HP E1340A
The AFG has 16 built-in arbitrary waveforms available for use. All of these
waveforms have 4096 points and are stored in an EPROM (see "Program
Comments" for the waveform listing). To execute the waveforms,
download the data points into waveform segment A, B, C, or D. The
following program downloads and generates the 16th waveform.
1. Reset the AFG -
*RST
The *RST command aborts waveform output and sets the AFG to a
defined state.
2. Setup the AFG for an Arbitrary Waveform Output -
[SOURce:]FREQuency[:CW|FIXed] <
[SOURce:]FUNCtion[:SHAPe] USER
[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPLitude] <
These commands setup the AFG to output an arbitrary waveform.
3. Download the Waveform Data from the EEProm into Memory -
[SOURce:]ARBitrary:DOWNload <
This command downloads the segment data from the EPROM where
< source > selects the waveform block in the EPROM,
waveform segment name (i.e., A, B, C, or D), and
waveform segment length (i.e., 4096).
4. Select the User Name -
[SOURce:]FUNCtion:USER <
This command selects the waveform segment to be output. Make the
name in this command the same name as the waveform segment to be
output.
