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.
Parameters:
<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 man-
ual 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.
Usage:
Event
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.
Parameters:
<RefLevel> Range: -160 to 160
Increment: 1
*RST: 0
Default unit: dB
SPECtrum:FREQuency:POSition <Frequency>
Configures the position of the spectrum within the vertical diagram grid. Changing this
value has the same effect as using the [POS] keys on the instrument.
Note that this command contains the keyword FREQuency for compatibility reasons. In
effect, it changes the level position in the spectrum diagram.
