If Step is set, the frequency for the next frequency step of the sweep is entered here.
SCPI command:
[:SOURce]:LFOutput:FREQuency:MANual on page 740
Spacing - LF Sweep
Selects linear or logarithmic sweep spacing.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:SPACing on page 745
Shape - LF Frequency Sweep
Selects the cycle mode for a sweep sequence (shape)
"Sawtooth"
One sweep runs from start to stop frequency. Each subsequent sweep
starts at the start frequency, i.e. the shape of the sweep sequence
resembles a sawtooth.
"Triangle"
One sweep runs from start to stop frequency and back, i.e. the shape of
the sweep resembles a triangle. Each subsequent sweep starts at the
start frequency.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:SHAPe on page 744
Step Lin/Log - LF Sweep
Sets the step width for the individual sweep steps. This entry is effective for all sweep
modes.
"Step Lin" or "Step Log" is displayed depending on whether "Spacing Lin" or "Log" is
selected.
"Step Lin"
With the linear sweep, the step width is a fixed frequency value which is
added to the current frequency. The linear step width is entered in Hz.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP[:LINear] on page 745
"Step Log"
With the logarithmic sweep, the step width is a constant fraction of the
current frequency. This fraction is added to the current frequency. The
logarithmic step width is entered in %.
SCPI command:
[:SOURce]:LFOutput:SWEep[:FREQuency]:STEP:LOGarithmic on page 746
Dwell Time - LF Sweep
Sets the dwell time. The dwell time determines the duration of the individual sweep steps.
