HPE6432_SetIGainDac

ViStatus HPE6432_SetIGainDac (ViSession instrumentHandle,

ViUInt16 iGainDac);

Purpose

This function sets a value for the I Gain DAC.

I Gain is used to enter compensation values for internal gain

impairments in the I signal path. Since it is the ratio of I Gain to

Q Gain that is important, it is usually only necessary to make

adjustments to I Gain or Q Gain, but not both.

Factory Preset Value: 2048 (Recommended)
