Specifies whether the contribution of the instrument noise is compensated for EVM computation.

You must measure the noise floor before applying the noise compensation. The instrument noise floor is measured for the RF path used by the OFDMModAcc measurement and cached for future use.

Supported devices: PXIe-5830/5831/5832/5646/5840/5841/5842/5860.
