SPECtrum:FREQuency:BANDwidth[:RESolution]:AUTO <State>
If enabled, the optimal resolution bandwidth is determined automatically by the spect-
rum application according to the frequency span and selected window type.
If disabled, the RBW is set according to the ratio defined by SPECtrum:FREQuency:
BANDwidth[:RESolution]:RATio auf Seite 359.
Parameter:
<State> ON | OFF
*RST: ON
SPECtrum:FREQuency:BANDwidth[:RESolution]:RATio
<RBWRatio>
Determines the resolution of the spectrum, that is: the minimum distance between two
distinguishable frequencies.
If you change the span, the RBW is automatically adjusted to the minimum or maxi-
mum allowed value, if necessary.
In FFT mode, this command is read-only.
Parameter:
<RBWRatio> R10 | R20 | R50 | R100 | R200 | R500 | R1K
R10
Corresponds to the „RBW:Span Ratio“ setting „1:10“ in manual
operation.
R1K
Corresponds to the „RBW:Span Ratio“ setting „1:1000“ in
manual operation.
*RST: R200
SPECtrum:FREQuency:FULLspan
This command is only available in Spectrum mode. It sets the displayed frequency
range to the entire measured span.

SPECtrum:FREQuency:MAGNitude:REFerence[:VALue] <RefLevel>
Defines the expected maximum input signal level. Signal levels above this value may
not be measured correctly. The reference level is also used as the maximum on the y-
axis.
This command is only available in Spectrum mode.
