SCPI for the Arbitrary Waveform Generator
The eLABin1 four-channel Arbitrary Waveform Generator (AWG) can be remotely controlled by SCPI commands. Below are the SCPI commands for each of the subsystems of the AGW listed in tables. |
 |
Communication with the device
| Command | Description | ||
|---|---|---|---|
AWG |
Switches to the AWG from the main screen or from another instrument | ||
Common commands
The following Common Commands apply to the entire configuration of the Arbitrary Waveform generator only when the Arbitrary Waveform generator is the instrument in foreground. As Common Commands are based in the current context, they apply to the current instrument, when the current view is the main screen. Commands apply for the entire configuration of the eLABin1.
| Command | Description | ||
|---|---|---|---|
AWG:*IDN? |
Returns the SCPI identification string of the Arbitrary Waveform Generator. | ||
AWG:*RST |
Resets the Arbitrary Waveform Generator | ||
AWG:*SAV {A|B|C|D} |
Saves the Arbitrary Waveform Generator state on the selected memory slot. | ||
AWG:*WAI |
The Wait-to-Continue (WAI) command causes the waveform generator to wait until all pending commands are completed, before executing any other commands. | ||
