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 ADC coupling mode.
: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. This command requires firmware
revision 0.95 or higher.
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.
