350 User Manual 1175.7445.02 ─ 08
This softkey requires the following "Trigger Mode" (see "Trg/Gate Source"
on page 346):
span > 0 External or IF Power/BB PowerIF Power
span = 0 External or IF Power/BB PowerIF Power or Video
If a different mode is active, the IF Power/BB Power trigger mode is automatically
selected.
Note: When triggering or gating is activated, the squelch function is automatically dis-
abled (see "Squelch" on page 392).
If the gate is switched on, a gate signal applied to the rear panel connector "EXT TRIG-
GER/GATE" or the internal IF power detector controls the sweep of the analyzer.
In the trigger mode Time , this softkey is not available.
For details also see Chapter 6.2.8.3, "Using Gated Sweep Operation" , on page 352.
Remote command:

Gate Settings
Opens a submenu to make all the settings required for gated sweep operation.
In the "Time" trigger mode, this softkey is not available.
For details also see Chapter 6.2.8.3, "Using Gated Sweep Operation" , on page 352.
Gate Mode (Lvl/Edge) ← Gate Settings
Sets the gate mode. As settings level-triggered or edge-triggered gate mode can be
selected.
For details also see Chapter 6.2.8.3, "Using Gated Sweep Operation" , on page 352.
"Edge" Edge-triggered gate mode
"Lvl" Level-triggered gate mode
This mode is not supported when using R&S Power Sensors as
power triggers ("Trg/Gate Source" =
Power Sensor or External ).
Remote command:
[SENSe:]SWEep:EGATe:TYPE
on page 811
Gate Delay ← Gate Settings
Opens an edit dialog box to enter the gate delay time between the gate signal and the
continuation of the sweep. 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 stabi-
lization of an RF carrier.
As a common input signal is used for both trigger and gate when selecting the "Exter-
nal" or "IF Power" trigger mode, changes to the gate delay will affect the trigger delay
(trigger offset) as well.
For details also see Chapter 6.2.8.3, "Using Gated Sweep Operation" , on page 352.
