• RMS Noise Calculation RMS phase noise is calculated over a user specified integration range.
• Number of data points used All, ½ , ¼ , ⅛

Direct phase noise readout
Just position the spot frequency cursor at any offset frequency after you make a measurement, and the phase noise is numerically displayed.

Variable filtering
Now you can control trade-offs between measurement repeatability and measurement speed.

Calculation of RMS noise
RMS phase noise is integrated over a user-specified range under the phase noise curve and displayed in radians and degrees.

Spot frequency measurements Quickly measure phase noise at a single frequency offset.

Digitized hardcopy and storage Data can be printed and plotted, and traces can be stored in internal memory for future use.
