Keysight 53230A - Sense:frequency:gate:polarity

SENSe:FREQuency:GATE:POLarity
Syntax
[SENSe:]FREQuency:GATE:POLarity {POSitive | NEGative}
[SENSe:]FREQuency:GATE:POLarity?
Description
This command selects the polarity for the Gate In/Out BNC when externally gating of frequency, fre-
quency ratio, average period, PRF, and PRI measurements is selected (see
SENSe:FREQuency:GATE:SOURce command).
l POSitive starts the measurement on a positive edge on the Gate In/Out BNC, and stops the
measurement on the next negative edge.
l NEGative starts the measurement on a negative edge on the Gate In/Out BNC, and stops the
measurement on the next positive edge.
Remarks
l The instrument selects negative polarity after a Factory Reset (*RST command) or an Instrument Preset
(SYSTem:PRESet command).
Return Format
The query returns the gate open slope: POS or NEG.
Examples
The following example makes a frequency measurement on channel 1 using external gating. The gate
opens on a negative edge on the Gate In/Out BNC, and closes on the next positive edge:
CONF:FREQ 1.2E6
FREQ:GATE:SOUR EXT
FREQ:GATE:POL NEG
