SENSe:FUNCtion

This command configures the sensing function for triggered measurements. The dc source has two measurement sensors as described below. The query returns the function setting.

CURRent Senses the output current at the selected output

VOLTage Senses the output voltage at the selected output

Command Syntax	SENSe:FUNCtion <function>, (@<channel list>)
Parameters	"VOLTage" "CURRent"
*RST Value	VOLT
Examples	SENS:FUNC "VOLT",(@1)
Query Syntax	SENSe:FUNCtion? (@<channel list>)
Returned Parameters	<SRD>

SENSe:SWEep:NPLCycles

This command specifies the total measurement acquisition time in terms of ac power line cycles. It automatically sets the sweep time interval, sweep offset, and sweep points. The values are chosen to sample the maximum number of points possible and to provide the best noise filtering.

Command Syntax	SENSe:SWEep:NPLCycles <NRf+>
Parameters	1 through <n>
*RST Value	0.00912 (for 60Hz line)
Examples	0.0076 (for 50Hz line)
Examples	SENS:SWE:NPLC 10
Query Syntax	SENSe:SWEep:NPLCycles?
Returned Parameters	<NR3>

SENSe:SWEep:OFFSet:POINts

This command defines the offset in a data sweep when an acquire trigger is used. Negative values represent data samples taken prior to the trigger. Positive values represent the delay after the trigger occurs but before the samples are acquired.

Command Syntax	SENSe:SWEep:OFFSet:POINts <NRf+>
Parameters	-4095 through 2,000,000,000
*RST Value	0
Examples	SENS:SWE:OFFS:POIN -2047
Query Syntax	SENSe:SWEep:OFFSet:POINts?
Returned Parameters	<NR3>
Related Commands	SENS:SWE:TINT SENS:SWE:POIN MEAS:ARR
