Noise Correction can reduce the noise contribution of the analyzer to the measurement results as
much as 10 dB. When the measured power is close to the noise floor, turning on the Noise Correction
under the Meas Setup menu can make the measurement more accurate. The correction will only be
valid for current measurement parameters.
To correctly use the Noise Correction feature, you MUST re-calibrate the correction (set to Off,
then On) after ANY measurement parameters are changed. Failure to re-calibrate the Noise
Correction will provide invalid data. When Noise Correction is On, the screen annotation NCORR is
shown below the Input.
