R&S FSP Remote Control – Description of Commands
SENSe Subsystem
6.202 Operating Manual 1164.4556.12 - 06
[SENSe<1|2>:]SWEep:EGATe ON | OFF
This command switches on/off the sweep control by an external gate signal. If the external gate is
selected the trigger source is automatically switched to EXTernal as well.
In case of measurement with external gate, the measured values are recorded as long as the gate is
opened. There are two possibilities:
– The gate is edge-triggered (
"SWEep:EGATe:TYPE EDGE"
):
After detection of the set gate signal edge, the gate remains open until the gate delay (
SWEep:
EGATe:HOLDoff
) has expired.
– The gate is level-triggered (
"SWEep:EGATe:TYPE LEVel"
):
After detection of the gate signal, the gate remains open until the gate signal disappears.
A delay between applying the gate signal and the start of recording measured values can be defined
with
SWEep:EGATe:HOLDoff
.
During a sweep the gate can be opened and closed several times. The synchronization mechanisms
with *OPC, *OPC? and *WAI remain completely unaffected.
The sweep end is detected when the required number of measurement points (625 in analyzer mode)
has been recorded.
Example:
"SWE:EGAT ON"
'Switches on the external gate mode.
"SWE:EGAT:TYPE EDGE"
'Switches on the edge-triggered mode.
"SWE:EGAT:HOLD 100US"
'Sets the gate delay to 100 µs.
"SWE:EGAT:LEN 500US"
'Sets the gate opening time to 500 µs.
"INIT;*WAI"
'Starts a sweep and waits for its end.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
[SENSe<1|2>:]SWEep:EGATe:HOLDoff 125 ns to 100 s
This command defines the delay time between the external gate signal and the continuation of the
sweep.
Example:
"SWE:EGAT:HOLD 100us"
Characteristics: *RST value: 0s
SCPI: device-specific
Mode: A
