QUERY MEASUREMENT

QM

Purpose:

To obtain measurement data from an oscilloscope.

If the V (Value) parameter is specified, one measured value will be returned.

If the L (Logging) parameter is specified, an infinite number of measured values will be returned. Cancelling is possible by sending the ASCII character ESC.

If no V or L parameter is specified, one measured value is returned, preceded by its type, and concluded by its suffix.

Note: If averaging is on, the values will be averaged over the number of average counts.

Command:
