5.15.1. SENSe:APERture

Syntax	SENSe:APERture {<period>} SENSe:APERture?
Modules	MIO
Description	This command sets the integration time for one point measurement. The APERture value is coupled to NPLCycles by the equation: APERture = NPLCycles / selected AC line frequency. For example, for NPLC of 5 and 50 Hz the integration time is 100 ms. The AC line frequency is not detected automatically, therefore it has to be set with the SYSTem:LFRequency command. Using an integer number of power line cycles can reduce measurement noise from line frequency sources.
Parameters	Name	Type	Range	Default
	<period>	NR2	0 – 0.5	–
Return	The query command returns the present setting of the integration time.
Usage example	SENS:NPLC 5 SENS:APER? 0.1
