SCPI for the Oscilloscope

The eLABin1 Oscilloscope (OSC) can be remotely controlled by SCPI commands.

Below are the SCPI commands for each of the subsystems of the OSC listed in tables.
OSC

Communication with the Oscilloscope

Table 1. Communication with the OSC
Command Description
OSC Switches to the OSC from the main screen or from another instrument

Common commands

The following Common Commands apply to the entire configuration of the Oscilloscope only when the Oscilloscope 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.

Table 2. Common Commands
Command Description
OSC:*IDN? Returns the SCPI identification string of the oscilloscope.
OSC:*RST Resets the oscilloscope.
OSC:*SAV {A|B|C|D} Saves the Oscilloscope state on the selected memory slot.
OSC:*WAI The Wait-to-Continue (WAI) command causes the oscilloscope to wait until all pending commands are completed, before executing any other commands.
