:CALCulate:FFT:VSMode
Syntax
:CALCulate:FFT:VSMode <vmode>
:CALCulate:FFT:VSMode?
Description
Set or query the vertical scale type of the FFT operation result.
Parameter
Name Type Range Default
<vmode> Discrete {VRMS|DB} DB
Return Format
The query returns VRMS or DB.
:CALCulate:FFT:VSCale
Syntax
:CALCulate:FFT:VSCale <vscale>
:CALCulate:FFT:VSCale?
Description
Set or query the vertical scale of the FFT operation result. The unit is related to the current vertical scale
type of FFT operation and the amplitude unit of the signal source channel.
Parameter
Name Type Range Default
<vscale> Real
Related to the current vertical scale type of FFT operation:
dB: 1 to 100
Vrms: the default range is from 0.01 to 200. The actual range is
related to the vertical scale of the signal source channel.
20dBV/div
Note: For the vertical scale type of FFT operation, refer to the :CALCulate:FFT:VSMode command. For the channel
vertical scale, refer to the
:CHANnel<n>:SCALe command. Once you change the channel vertical scale, the range of
<vscale> will be changed only after the MATH channel is re-activated.
Return Format
The query returns the vertical scale of the FFT operation result in scientific notation.
