Toggles between single sweep and continuous sweep mode.
In continuous mode (Single (All Chans) not selected), the analyzer measures continuously, repeating the current sweep.
In single sweep mode, the measurement is stopped after the number of sweeps selected in the Define Restart dialog.
Press Single to
activate the single sweep mode and start a single sweep sequence. To start
further sweep sequences press Restart.

Stops the ongoing measurement and restarts a new measurement sequence. In Single sweep mode a new single sweep sequence is started, according to the Define Restart settings.
It is possible to set all traces to zero when a Restart is executed; see System

Behavior.

Remote control: |
Opens a dialog to configure the Single sweep mode.
Number of Sweeps selects the number of sweeps to be measured in single sweep mode: either one (Single Sweep) or a group of consecutive sweeps.
Scope defines whether the active sweep mode (single or continuous) and the Number of Sweeps are valid for the Active Channel only or for All Channels in the active setup. If All Channels is selected, the number of sweeps in the single sweep sequence is equal to the selected Number of Sweeps times the number of channels. The sequence starts with the first sweep in channel no. 1.
In remote control, it is possible to retrieve the results
acquired in any of the sweeps within a single sweep group; see Sweep
History.

Opens a dialog to configure the BUSY output signal at pin no. 4 of the USER CONTROL connector on the rear panel of the analyzer.
Auto couples the BUSY signal to the active triggered measurement sequence (Channel – Sweep – Trigger – Trigger Settings). After a Preset, the analyzer triggers an entire sweep. The BUSY signal is turned on ("High" state) when the analyzer acquires the fist partial measurement data of the first sweep point. It returns to "Low" state after the last partial measurement of the last sweep point has been acquired.
The remaining settings select a fixed behavior. The BUSY signal monitors the duration of a sweep, sweep segment, sweep point, or partial measurement.
In Alternating
sweep mode, the BUSY signal can be used to monitor either each Partial
Measurement or the entire Sweep.
Avoid the busy signal settings Point
or Sweep Segment in combination
with alternating mode, since
they may cause misleading results.
In multi-channel setups where the busy signal monitors an entire sweep,
the exact behavior depends on the restart scope (Channel
– Sweep
– Define
Restart –
Scope). The busy signal is active over All
Channels or over the Active Channel, depending on
the restart scope settings.
The BUSY signal monitors the data acquisition phase, irrespective of the time required for sweep preparation and subsequent data processing stages.
