niSync_CalAdjustDDSStartPulsePhaseVoltage

C Function Prototype

ViStatus niSync_CalAdjustDDSStartPulsePhaseVoltage (ViSession vi, ViReal64 newVoltage, ViReal64* oldVoltage);

Purpose

Sets the DDS start pulse phase voltage to be written to the specified device's non-volatile onboard memory using an external calibration reference.

The value you enter for newVoltage is written to the non-volatile onboard memory of the specified device and becomes the new calibration constant only if you set the action parameter of niSync_CloseExtCal to NISYNC_VAL_EXT_CAL_COMMIT.

Notes  

Parameters

Name Type Description
vi ViSession The session handle that you obtain from niSync_InitExtCal. The handle identifies the device to calibrate.

Default Value: None

newVoltage ViReal64 Specifies the new DDS start pulse phase voltage value, in volts, to write to the non-volatile onboard memory of the instrument you are calibrating.

oldVoltage ViReal64 Returns the DDS start pulse phase voltage, in volts, last written to the device's non-volatile onboard memory.
