Sweep/Control
The SCPI commands used for these are the same for Trigger and Gate, since there is only one setting
which affects both Gate and Trigger. Example: to set the Trigger Level for External 1 you use the
command :TRIG:EXT1:LEV regardless of whether you are using External 1 as a Trigger Source or a
Gate Source.
Control Edge/Level
Sets the method of controlling the gating function from the gating signal.
Edge
In Edge triggering, the gate opens (after the Delay) on the selected edge (for example, positive) of the
gate signal and closes on the alternate edge (for example, negative).
Level
In Level triggering, the gate opens (after the Delay) when the gate signal has achieved a certain level and
stays open as long as that level is maintained.
Key Path: Sweep/Control, Gate
Remote Command: [:SENSe]:SWEep:EGATe:SOURce EXTernal1|EXTernal2
|LINE|FRAMe|RFBurst
[:SENSe]:SWEep:EGATe:SOURce?
Dependencies: In some models, there is no second External input. In these models, the
External 2 key is blanked and the EXTernal2 parameter will generate a
“Hardware missing; Not available for this model number” error.
Preset: EXTernal 1
GSM/EDGE: FRAMe
Backwards Compatibility Notes: In ESA, there is a single Gate input port. In PSA, the Gate Source may be
taken from one of two specified input ports. In the X-Series, any Trigger
Source can be a Gate Source.

Edge is selected.
