:MATH:FFT:SPLit
:MATH:FFT:SPLit <bool>
:MATH:FFT:SPLit?
Enable or disable the half-screen display mode of the FFT operation, or query the status
of the half display mode of the FFT operation.
 Enable the half-screen display mode: the source channel and the FFT operation
results are displayed separately. The time domain and frequency domain signals are
displayed clearly.
 Disable the half-screen display mode (full-screen display mode): the source channel
and the FFT operation results are displayed in the same window to view the
frequency spectrum more clearly and to perform more precise measurement.
The query returns 1 or 0.
:MATH:FFT:SPLit OFF /*Disable the half-screen display mode*/
:MATH:FFT:SPLit? /*The query returns 0*/
:MATH:FFT:UNIT
:MATH:FFT:UNIT <unit>
:MATH:FFT:UNIT?
Set or query the vertical unit of the FFT operation result.
The query returns VRMS or DB.
:MATH:FFT:UNIT VRMS /*Set the vertical unit of the FFT operation result to Vrms*/
:MATH:FFT:UNIT? /*The query returns VRMS*/
