SENSe:FREQuency:GATE:SOURce
Syntax
[SENSe:]FREQuency:GATE:SOURce {TIME | EXTernal | INPut[1] | INPut2 | ADVanced}
[SENSe:]FREQuency:GATE:SOURce?
Description
This command selects the gate source for frequency, frequency ratio, average period, PRF, and PRI meas-
urements.
l TIME configures the instrument to start the measurement immediately after a trigger and trigger delay
following after an INITiate:IMMediate, READ?, or MEASure? command. SENSe:FREQuency:GATE:TIME
controls the time the gate remains open.
l EXTernal configures the instrument to gate the measurement using the Gate In/Out BNC after a trigger
and trigger delay following after an INITiate:IMMediate, READ?, or MEASure? command. The
SENSe:FREQuency:GATE:POLarity command controls the polarity of the Gate In/Out BNC. The Gate
In/Out BNC cannot be used to externally gate a measurement while generation of the gate signal is
enabled (OUTPut:STATe ON set).
l INPut[1] configures the instrument to gate the measurement using the channel 1 input after a trigger
and trigger delay following after an INITiate:IMMediate, READ?, or MEASure? command. The
SENSe:FREQuency:GATE:POLarity command controls the polarity of the input signal. Channel 1 can-
not be involved in the measurement and must be configured for fixed input threshold voltage (INPut
{1|2}:LEVel{1|2} command).
l INPut2 configures the instrument to gate the measurement using the channel 2 input after a trigger
and trigger delay following after an INITiate:IMMediate, READ?, or MEASure? command. The
SENSe:FREQuency:GATE:POLarity command controls the polarity of the input signal. Channel 2 can-
not be involved in the measurement and must be configured for fixed input threshold voltage (INPut
{1|2}:LEVel{1|2} command).
l ADVanced configures the instrument for advanced gating of the measurement via the SENSe:GATE
commands after a trigger and trigger delay following after an INITiate:IMMediate, READ?, or MEASure?
command.
Remarks
l When SENSe:FREQuency:MODE is set to CONTinuous, the gate source is ignored, and the meas-
urements start immediately after a trigger and trigger delay; the gate closes when SAMPle:COUNt
measurements have been made.
l The instrument sets the gate source to TIME after a Factory Reset (*RST command) or an Instrument
Preset (SYSTem:PRESet command).
