Triggering the Sweep – TRIG Key R&S FSL

Gate Delay (option Gated Sweep, B8)
Opens an edit dialog box to enter the gate delay time between the gate signal and the
continuation of the sweep. Values between 125 ns and 100 s are allowed. The delay position on
the time axis in relation to the sweep is indicated by a line labeled GD.
This is useful for e.g. taking into account a delay between the gate signal and the stabilization of
an RF carrier.
As a common input signal is used for both trigger and gate when selecting the External or IF
Power trigger mode, changes to the gate delay will affect the trigger delay (trigger offset) as
well.
For details also see "To use gated sweep operation (option Gated Sweep, B8)" on page 4.29.

Gate Length (Gate Mode Edge)
Opens an edit dialog box to enter the gate length. Values between 125 ns and 100 s are
allowed. The gate length in relation to the sweep is indicated by a line labeled GL.
The length of the gate signal defines if the sweep is to be interrupted. Only in the edge–triggered
mode the gate length can be set, while in the level–triggered the gate length depends on the
length of the gate signal.
For details also see "To use gated sweep operation (option Gated Sweep, B8)" on page 4.29.

Sweep Time (option Gated Sweep, B8)
Opens an edit dialog box to change the sweep time in order to obtain a higher resolution for
positioning gate delay and gate length. When quitting the Gate Settings submenu, the original
sweep time is retrieved.

IF Power Retrigger Holdoff
Opens an edit dialog box to define the value for the IF power trigger holdoff. This softkey is only
available if the IF power trigger is selected as the trigger source. The holdoff value in s is the
time which must pass since another IF power trigger event may happen. The range of the value
is between 150 ns and 10 s in the step width of 10 ns.
This softkey is available from firmware version 1.30.
