How to Use Noise Monitor

Evaluating a Single Offset Frequency

Press the SPAN softkey to increment the frequency span. The increment

values are the measurement ranges denned in the segment tables.

Press

Take Sweep

Take Sweep sets up the Interface, autoranges the

analyzer, measures the span, and holds the averaged display.

NOTE

Noise Monitor allows the user to manipulate the Front Panel

controls of the analyzer. After the Interface is set up, the

analyzer settings can be changed.

(Note that changing the bandwidth to other than the one

set up by the Take Sweep softkey will cause the Marker

function to return inaccurate data.)

Place the analyzer's marker at the desired frequency.

Select the appropriate Marker softkey to read and display the value of

the marker.

Evaluating Phase Fluctuations as a Function of Time

Real Time Noise measurements can be useful for evaluating noise tran-

sients or device sensitivity to mechanical or electrical stimulation. Contin-

uous Real Time display of the noise measurement can be made by turning

the averaging function on the analyzer off (or by setting the analyzer for

repeat display or continuous sweep.)
