Explanation
Define the vertical scale of the reference channel waveform when performing the store operation as
"Vscale0" and the vertical scale of the reference channel waveform currently set as "Vscale1". Different
<vscale> values are used to represent different ratio relations between Vscale0 and Vscale1, as shown in
the table below.
<vscale> Vscale1/Vscale0
1 0.05
2 0.1
3 0.2
4 0.5
5 1
6 2
7 5
8 10
9 20

The query returns an integer from 1 to 10. If the REF function is currently disabled or no reference
waveform is stored for the current reference channel, the query returns Null.
