:CALCulate:FFT:VSCale
Syntax
:CALCulate:FFT:VSCale <vscale>
:CALCulate:FFT:VSCale?
Description
Set the vertical scale of the FFT operation result.
Query the current vertical scale of the FFT operation result.
Parameter
Name Type Range Default
<vscale> Real
Related to the current FFT display
mode:
dBVrms: 1 to 100
Vrms: 0.01 to 200, related to the current
channel scale (from channel scale/128
to channel scale*128)
10dBVrms/div
Note:
For the FFT display mode, refer to the
:CALCulate:FFT:VSMode command.
For the channel scale, refer to the
:CHANnel<n>:SCALe command. Once you change the channel
scale, the range of <vscale> will be changed only after the MATH channel is re-activated.
Return Format
The query returns the vertical scale in scientific notation.
Example
:CALCulate:FFT:VSCale 2
The query returns 2.000000e+00.
