Short Name: Output Impedance

Property of niFgen

Specifies the output impedance of the signal generator at the output connector. NI signal generators have an output impedance of 50 ohms and an optional 75 ohms on select modules.

If the Load Impedance property value matches the output impedance, the voltage at the signal output connector is at the necessary level. The voltage at the signal output connector varies with load output impedance, up to doubling the voltage for a high-impedance load.

Note  You cannot change this property while the device is generating a waveform. If you want to change the device configuration, call the niFgen Abort Generation VI or wait for the generation to complete.
