4.15 Sense Subsystem - Sweep

This subsystem controls the measurement current range and the data acquire sequence of the

AC source.

Subsystem Syntax

SENSe

[:COUPle] AC | DC AC or DC coupling mode for measurements.

:SWEep

:OFFSet Define trigger delay in time relative to start of the

digitizer data record

:POINts <n> Define trigger points relative to the start of the

digitizer data record

:TINTerval <n> Sets the digitizer sample spacing

SENSe[:COUPle]

This command sets the coupling mode for the ADC of the measurement system. Available

coupling modes are AC or DC. Factory default is DC coupled.

Command Syntax SENSe[:COUPle] <CRD>

Parameters AC | DC

*RST Value DC

Examples SENS:COUP DC

Query Syntax SENS:COUP?

Returned Parameters <CRD>

Related Commands SENS:SWE:TINT

SENSe:SWEep:OFFSet

This command defines the trigger point expressed in seconds relative to the start of the returned

data record when an acquire trigger is used. The values can range from MIN to MAX depending

on the phase mode and the selected sample interval. When the values are negative, the values

in the beginning of the data record represent samples taken prior to the trigger.

Command Syntax SENSe:SWEep:OFFSet <NRf+>

Parameters <NRf> | MINimum | MAXimum

*RST Value 0

Examples SENS:SWE:OFFS -12E-3

Query Syntax SENSe:SWEep:OFFSet?

Returned Parameters <NR3>

Related Commands SENS:SWE:TINT MEAS:ARR

SENSe:SWEep:OFFSet:POINts

This command defines the trigger point expressed in sample points relative to the start of the

returned data record when an acquire trigger is used. The values can range from -4095 to 2E9.

When the values are negative, the values in the beginning of the data record represent samples

taken prior to the trigger.
