Specifies whether the measurement calibrates the noise floor of analyzer or performs the ModAcc measurement.

You do not need to use a selector string to configure or read this property for the default signal instance. Refer to the Selector Strings topic for information about the string syntax for named signals.

The default value is Measure.

The OFDMModAcc measurement is performed on the acquired signal.

Calibrate Noise Floor 1

The OFDMModAcc measurement measures the noise floor of the instrument across the frequency range of interest determined by the carrier frequency and channel bandwidth. In this mode, the measurement expects that the signal generator to be turned off and checks whether no signal power is detected at the RF In port of the analyzer beyond a certain threshold. All scalar results and traces are invalid in this mode. Even if the instrument noise floor is previously calibrated, the measurement performs all the required acquisitions and overwrites any pre-existing noise floor calibration data.
