Spurious Filter
Management
The spurious filter configuration table provides several management
tools:
●
"Insert": Adds a new offset frequency to the spurious filter.
●
"Delete": Removes an existing offset frequency from the spurious
filter.
●
"Clear": Clears the spurious filter.
●
"Save": Saves the spurious filter configuration. With this function,
the name of the spurious filter can be defined.
●
"Load": Loads an existing spurious filter configuration.

Frequency Stability Configuration
Access
: "Overview" > "Noise Config" > "Frequency Stability"
The results of the frequency stability measurements (
) are
derived from the phase noise measurement. Thus, the frequency stability measure-
ments and the phase noise measurement use the same configuration.
The "Frequency Stability" dialog contains the most important settings for the frequency
stability measurements. However, everything that you change in the
is also applied to the frequency stability measurements, and vice versa.
●
"Tau Start" and "Tau Stop"
Tau start and stop define the observation time Tau for the frequency stability mea-
surement. They are coupled to the
. Tau start is the reciprocal
value of the stop frequency offset. Tau stop is the reciprocal value of the start fre-
quency offset.
For example, a measurement range from 1
mHz to 1
MHz would result in an obser-
vation time from 1
µs to 1000
s and vice versa.
●
"RBW" and "XCORR"
Note that if you define the
ually, the values of the half decade configuration table are also applied to the fre-
quency stability measurements.
●
"Meas BW"
The measurement bandwidth (or integration bandwidth) is the reciprocal value of
"Tau Start".
