Center Frequency
Defines the frequency in the center of the displayed span for linear frequency scaling
(see "X-Scaling" on page 114). Usually, the center frequency is set to the highest mea-
sured power level in spectrum analysis.
To set the center frequency, you can also use the [POS] keys.
Remote command:
SPECtrum:FREQuency:CENTer on page 357
Span
Determines the measured frequencies and the visible range in the spectrum diagram
for linear frequency scaling (see "X-Scaling" on page 114). Depending on the selected
span, the time scale may be restricted (see "Time Scale" on page 46).
To set the span, you can also use the [TIME] keys.
The span must be within the range 1 kHz to 500 MHz.
Note that this range only affects the displayed spectrum, not the calculated results.
Remote command:
SPECtrum:FREQuency:SPAN[:VALue] on page 358
Start Frequency/ Stop Frequency
For logarithmic frequency scaling (see "X-Scaling" on page 114), the displayed fre-
quency range is defined by a start and a stop value, rather than a span and center fre-
quency. Note that this range only affects the displayed spectrum, not the calculated
results.
Remote command:
SPECtrum:FREQuency:STARt on page 358
SPECtrum:FREQuency:STOP on page 359
Resolution bandwidth (RBW)
The resolution bandwidth (RBW) determines the resolution of the spectrum, that is: the
minimum distance between two distinguishable peaks. The higher the resolution (the
smaller the ratio), the more peaks are detected, but the longer the measurement
requires to finish.
In manual operation, the RBW is defined in relation to the selected frequency span and
must lie between 1:1000 and 1:10. If you change the span, the RBW is automatically
adjusted to the minimum or maximum allowed value, if necessary. (In remote opera-
tion, the RBW can also be defined directly, independently of the span).
In Auto mode, the optimal resolution according to the frequency Span and selected
Window type is used. It is indicated for the "RBW" setting.
Remote command:
SPECtrum:FREQuency:BANDwidth[:RESolution]:AUTO on page 361
SPECtrum:FREQuency:BANDwidth[:RESolution]:RATio on page 361
SPECtrum:FREQuency:BANDwidth[:RESolution][:VALue] on page 357
