2.4.1.7 CNR (Carrier to Noise Ratio)
Measure the power of the carrier and noise of the specified bandwidth and their ratio. Select CNR and
press Meas Setup to set the corresponding parameters.
2.4.1.8 Harmonics
The harmonic power and total harmonic distortion of carrier signal are measured. The maximum
measurable harmonic is 10th harmonic. The fundamental wave amplitude of carrier signal must be
greater than - 50 dBm, otherwise the measurement result is invalid. Select Harmonics and press
Meas Setup to set the corresponding parameters.
2.4.1.9 Meas O
Turn o all the Meas functions.
