Ametek SEQUOIA Series - Voltage Measurement Subsystem

64 Sequoia Series
4.9 Voltage Measurement Subsystem
This subsystem programs the voltage measurement capability of the Sequoia Series. Two
measurement commands are available: MEASure and FETCh. MEASure triggers the acquisition of
new measurement data before returning a reading. FETCh returns a reading computed from
previously acquired data.
Individual outputs of a three-phase source are specified by the setting of INSTrument:NSELect.
Subsystem Syntax
MEASure | FETCh
[:SCALar]
:VOLTage
[:AC]? Returns ac rms voltage
:DC? Returns the dc component of the voltage
:HARMonic
[:AMPLitude]? <n> Returns amplitude of the Nth harmonic of voltage
:PHASe? <n> Returns phase of the Nth harmonic of voltage
:THD? Returns % of total harmonic distortion of voltage
MEASure:VOLTage[:AC]?
FETCh:VOLTage[:AC]?
Phase Selectable
These queries return the ac rms voltage being sourced at the output terminals.
Query Syntax MEASure[:SCALar]:VOLTage:AC?
FETCh[:SCALar]:VOLTage:AC?
Parameters None
Examples MEAS:VOLT:AC? FETC:VOLT:AC?
Returned Parameters <NR2>
Related Commands INST:NSEL
MEASure:VOLTage:DC?
FETCh:VOLTage:DC?
Phase Selectable
These queries return the dc component of the output voltage being sourced at the output terminals.
This command should be used when the voltage mode is set for DC or ACDC
