5.5.14 RF Sweep and List Mode
5.5.14.1 Overview
The R&S SMJ offers three different sweep types (frequency sweep, level sweep and
LF sweep) to be activated alternatively. Each type has 6 modes which differ with
respect to the sweep cycle mode (continuous, individual and step-by-step) and trigger-
ing mode (automatic, internal and external).
●
Sweeps and list mode can not be activated simultaneously, they deactivate each
other.
●
If you want to remain at a specific frequency or level value during a sweep, enter
the value directly in the status bar. The sweep stops immediately.
●
A phase continuous frequency sweep can be generated after activating the phase
continuous mode, see
"Setting a Phase Continuous Frequency Sweep"
on page 207.
Setting a sweep
A sweep is set in five basic steps which are shown below taking a frequency sweep as
an example.
1. Set the sweep range ("Start Freq" and "Stop Freq" or "Center Freq" and "Span").
2. Select linear or logarithmic sweep spacing ("Spacing").
3. Set the step width ("Step Lin/Log") and dwell time ("Dwell Time").
4. Activate the sweep ("Mode" to Auto, Single, Step or Extern Single, Extern Step).
