CALCulate:MATH<m>:FFT:BANDwidth[:RESolution]:AUTO <State>
Couples the frequency span to the RBW.
Suffix:
<m>
.
1..8
math waveform
Parameters:
<State> ON | OFF
*RST: ON
Usage: Asynchronous command
CALCulate:MATH<m>:FFT:BANDwidth[:RESolution]:RATio <SpanRBWRatio>
This command defines the ratio of span (Hz) / resolution bandwidth (Hz).
Suffix:
<m>
.
1..8
math waveform
Parameters:
<SpanRBWRatio> ratio span / resolution bandwidth
Range: 1 to 1000
Increment: 1
*RST: 100
Usage: Asynchronous command
CALCulate:MATH<m>:FFT:BANDwidth[:RESolution][:VALue] <ResolutionBW>
This command defines the resolution bandwidth.
Suffix:
<m>
.
1..8
math waveform
Parameters:
<ResolutionBW> resolution bandwidth
Range: 0.01 to 160E+6
Increment: 0.01
*RST: 2E+6
Default unit: Hz
Usage: Asynchronous command
CALCulate:MATH<m>:FFT:WINDow:TYPE <WindowType>
Windowing helps minimize the discontinuities at the end of the measured signal inter-
val and thus reduces the effect of spectral leakage, increasing the frequency resolu-
tion.
