6.9.1 Frequency Configuration
Access : "Overview" > "Frequency"
The frequency settings define the frequency characteristics of the signal and the
amount of frequency information that is displayed.
The remote commands required to configure the frequency are described in Chap-
ter 11.6.9.1, "Frequency Configuration" , on page 386.

Selecting the measurement mode
Transient analysis has two measurement modes, wideband and narrowband mode.
The measurement mode selects the signal path that is used to measure the signal.
●
Wideband mode ("Wide")
Select the wideband mode for measurements with a span >
40 MHz.
Wideband mode only works in the frequency range between 256 MHz and 8 GHz.
Thus, the maximum span is 7.774 GHz. Supported center frequencies are in the
range between 276 MHz and 7.980 GHz.
●
Narrowband mode ("Narrow")
Select the narrowband mode for measurements with a span <
40 MHz.
Narrowband mode works over the complete frequency range supported by your
R&S
FSPN.
If you select a span > 40 MHz in the specified frequency range, the R&S FSPN auto-
matically selects the wideband mode.
If you select a span < 40 MHz, the R&S FSPN automatically selects the narrowband
mode. The R&S FSPN also selects the narrowband mode automatically if you define a
frequency that is outside of the frequency range supported by the wideband mode and
reduces the span (for example a center frequency of 100
MHz reduces the span to
40 MHz).
