THE CPL PROTOCOL
QUERY WAVEFORM
Purpose:
To obtain a complete waveform from the oscilloscope.
You can use the PW command to send the data received with the QW query back
to the oscilloscope.
The option ",A" can be used to recall the date and time in the customized format.
When compatibility with initial versions of these oscilloscopes is required this ",A"
option should be omitted.
Note:
The number of data bits of the RS-232 interface must be 8 (not 7);
otherwise an execution error will be given.
