2.4 VISA Initialization AC output voltage is set using the Vrms unit (when the waveform is SIN or SQU) or Vp-p units (when waveform is ARB). When in AC-EXT or AC+DC-EXT mode, the output AC voltage cannot be set or queried. ([3,"Invalid in this mode"] error occurs.) Voltage[Vpp]/[Vrms] This sets the output AC voltage. Setting range varies according to waveform and range. The default setting is “0.0”.
APS-1102 LabVIEW Driver Manual setting is “–400.0”. Rn_set This specifies the range to be set. The default setting is “100 V (False)”.
2.7 MEASure Subsystem 2.7 MEASure subsystem GW APS-1102 MEAS Curr.vi This returns the output current RMS value (AC+DC RMS value) in Arms units.
APS-1102 LabVIEW Driver Manual GW APS-1102 MEAS Curr Res.vi This resets the stored output current peak value (hold) to 0 Apk. GW APS-1102 MEAS Curr Ave.vi This returns the output current average value (AC+DC average value) in A units.
2.7 MEASure Subsystem This outputs presence/absence of measurement errors in an array. “True” is set to the position where a measurement error occurs. GW APS-1102 MEAS Curr Rat.vi This returns the ratio (%) of the nth harmonic current to the fundamental current as 100%. However, when in AC-INT mode, if the frequency is neither 50 Hz nor 60 Hz, the harmonic current cannot be measured. ([3, “Invalid in this mode”] or [6, “Invalid in this frequency”] error occurs.
APS-1102 LabVIEW Driver Manual When a measurement error occurs, “True” is set. GW APS-1102 MEAS Ac Pfac.vi This returns the output’s power factor. The power factor is calculated as “active power/apparent power”.

2.9 STATus Subsystem When the PTR filter is set to 1, WRER is set to 1 when WRCR changes from 0 to 1. When the NTR and PTR filters are both set to 1, WRER is set to 1 when WRCR changes. When the NTR and PTR filters are both set to 0, changes in WRCR are not propagated to WRER. NTR set This sets the NTR filter. The default setting is “0”. PTR set This sets the PTR filter. The default setting is “0”.

When in AC-EXT, AC-ADD, AC+DC-EXT or AC+DC-ADD mode, the output waveform setting cannot be made ([3, “Invalid in this mode] error occurs) Gain_Rn100V This sets the external input gain in the 100 V range. The default setting is “0.0”. Gain _Rn200V This sets the external input gain in the 200 V range.

2.12 TRACe Subsystem 2.13 SYSTem subsystem GW APS-1102 SYST Beep.vi This controls on/off of beep sound. Beep This sets beep sound on/off. The default setting is “ON”.
APS-1102 LabVIEW Driver Manual Pon This sets the output status at power-on. The default setting is “OFF”.
2.14 PROGram Subsystem 2.14 PROGram subsystem GW APS-1102 PROG Exec.vi This controls sequence operations. Control is performed using the STOP (stop), START (run), HOLD (hold), BRANCH0 (branch 0), or BRANCH1 (branch 1) parameter. When in AC-EXT, AC-SYNC, AC+DC-EXT, or AC+DC-SYNC mode, sequences cannot be executed. ([3,"Invalid in this mode"] error occurs.) When output OFF, sequence execution is disabled. ([2,"Invalid with output off"] error occurs.
APS-1102 LabVIEW Driver Manual 2.15 Common commands GW APS-1102 CLS.vi This clears the following registers: Standard event register Operation event register Warning event register Status byte Error queue GW APS-1102 ESE.vi This sets the standard event enable register. The setting range is 0 to 255. ESE This sets the standard event enable register. The default setting is “0”.
2.14 PROGram Subsystem GW APS-1102 OPC.vi When all operations have been completed, this sets the standard event register’s OPC bit (BIT0). *OPC? returns “1” when all operations have been completed. However, the standard event register OPC bit is not cleared zero *OPC? is executed.
