Description
Set or query the vertical scale of the current refrence channel waveform. The unit is the same with that of
the current signal source.
Parameter
Name Type Range Default
<vscale> Integer 1 to 10 5
Explanation
The vertical scale (
X
) set by thic command, the number of grids occupied by the original waveform (
N
)
and the number of grids occupied by the reference waveform (
1N
) fulfill the following equation.
( 5)
1 *2
X
NN
−
=
By default, the REF function is disabled. At this point, the query command returns Null. When the REF
function is enabled and reference waveform is stored for the current reference channel, the vertical scale
is 5 by default; namely, the size of the reference waveform equals that of the original waveform.
Return Format
The query returns an integer. If no reference waveform is stored for the current reference channel, the
query returns Null.
