SPECtrum:FREQuency:STARt
Defines the start frequency of the displayed frequency domain at the left display edge:
Center - Span/2
You can set start and stop frequency instead of defining a center frequency and span.
Parameters:
<StartFrequency>
Range:
Depends on various other settings, mainly on time
base, span/RBW ratio, and center frequency.
SPECtrum:FREQuency:STOP
Defines the stop frequency of the displayed frequency domain at the right display
edge:
Span/2
You can set start and stop frequency instead of defining a center frequency and span.
Parameters:
<StopFrequency>
Range:
Depends on various other settings, mainly on time
base, span/RBW ratio, and center frequency.
SPECtrum:FREQuency:BANDwidth[:RESolution][:VALue]
<ResolutionBandwidth>
Defines the resolution bandwidth - the minimum frequency step at which the individual
components of a spectrum can be distinguished.
Parameters:
<ResolutionBandwidth>
Range:
Depends on various other settings.
SPECtrum:FREQuency:BANDwidth[:RESolution]:RATio
<SpanRBWratio>
Defines the ratio of span (Hz) / resolution bandwidth (Hz). The span/RBW ratio is half
the number of points used for FFT which is defined with manual operation in the menu.
Parameters:
<SpanRBWratio>
Range:
The value is changed in 2^n steps from 2^10 to
2^15 (1024, 2048,4096,8192,16384, 32768).
