Properties

NameDescription
Enabled

Gets or sets whether the I/Q impairment is enabled.

GainImbalance

Gets or sets the gain imbalance of the I/Q modulator (I versus Q), in dB.

IOffset

Gets or sets I-signal DC offset when using a National Instruments arbitrary waveform generator (AWG).

OffsetUnits

Gets or sets the units of IOffset and the QOffset.

Note

For any devices except PXIe-5820, if the RfsgIQOffsetUnits method is set to Volts, a 0.1 I offset results in a 0.1 V offset in the output. For PXIe-5820 devices, 0.1 I offset results in a 10% offset in the output.

QOffset

Gets or sets the Q-signal DC offset when using a National Instruments arbitrary waveform generator (AWG).

Skew

Gets or sets the adjustment of the phase angle between the I and Q vectors. If this skew is zero, the phase angle is 90 degrees.
