the current signal source.
Parameter
Name Type
<vscale> Integer
Explanation
The vertical scale ( ) set by thic command, the number of grids occupied by the original waveform (
X
and the number of grids occupied by the reference waveform (
By default, the REF function is disabled. At this point, the query command returns Null. When the REF
