Spectrum". See
Chapter 4.3, "Measurement Mode" , on page 41.
●
"RF Freq"
Nominal measurement frequency of the RF signal, see
"RF Freq" on page 111.
●
Frequency range
"AF Center", "AF Span", "AF Start", "AF Stop"
The swept frequency range, see
Chapter 6.1.1, "Configuring the Frequency
Range" , on page 101.
●
RF attenuation ("Att")
The used attenuation mode; see also
"RF Mode" on page 60.
●
Resolution Bandwidth ("RBW")
Resolution bandwidth with which the measurement is performed. See
"Resolution
Bandwidth (RBW Mode/Res BW)" on page 103.

6.3.1 Configuring the Frequency Range
Access : [CH F]
Access VNC : [q]
The following settings configure the frequency range of the spectrum, that is: the x-
axis.
Define the frequency range to be displayed using one of the following methods:
●
AF Center + AF Span : the center frequency is displayed in the center of the x-axis,
with half the span to the either side
●
AF Start + AF Stop : the x-axis starts with the start frequency and ends with the
stop frequency
RF Freq ........................................................................................................................111
AF Center .................................................................................................................... 112
AF Span .......................................................................................................................112
AF Start ....................................................................................................................... 112
AF Stop ........................................................................................................................112
RF Freq
Configures the nominal frequency of the measurement. The configured value is dis-
played as "RF Freq" in the measurement settings area.
