Characteristics: *RST value: 0
SCPI: conform
Mode: R, A
[SENSe<1|2>:]SWEep:COUNt:CURRent?
This query command returns the current number of started sweeps/scans. A sweep/scan count value
should be set and the device should be in single-sweep/scan mode. This command is a query and
therefore has no *RST value.
Example:
"SWE:COUNt 64"
'sets sweep count to 64
"INIT:CONT OFF"
'switches to single-sweep mode
"INIT"
'starts a sweep (without waiting for the sweep end!)
"SWE:COUN:CURR?"
'queries the number of started sweeps
Characteristics: *RST value: --
SCPI: conform
Mode: R, A
[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.
