:DIFF:YTOP?
Query Syntax
:DIFF{1:8}{A|C}:YTOP?
Where the required specifier {1:8}{A|C} identifies the differential channel by its module slot and channel letter. For example, the differential waveform of channels 1A and 1B would be identified as :DIFF1A.
The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.
Description
Queries the amplitude value represented by the graticule's top edge. To query the amplitude value represented by the graticule's bottom edge, use :DIFF:YBOTtom?. Use the :DIFF:YSCale command to set the amplitude scale (volts or Watts). Use the :DIFF:YOFFset command to set the amplitude offset.
Example Command
:DIFF2A:YTOP?
