THE CPL PROTOCOL
CALIBRATE
Purpose:
To start the internal Auto-Calibration procedure. This procedure optimizes the
input, trigger and time base circuitry of the oscilloscope. This calibration takes
approximately one minute and completion is signalled by the acknowledge.
The Calibrate (CL) command performs the same function as pressing the front
panel CAL button for more than 2 seconds.
Command:
"CL"
Response:
acknowledge
Note: The <acknowledge> will be sent after the calibration has been fully
completed. A detailed error report may be queried for using the ST
command (only if acknowledge is not zero).
Example:
