Optimizing Measurements
Increasing Network Analyzer Dynamic Range
Changing Measurement
In averaging mode, the analyzer measures each frequency point once per
Averaging
sweep and averages the current and previous trace up to the averaging factor
specified by the user. The instrument computes each data point based on an
exponential average of consecutive sweeps weighted by the
averaging factor.
As the averaging factor is increased:
signal-to-noise ratio increases
l
time for each individual sweep remains the same, but
l
total time to update the trace increases.
Averaging is better than system bandwidth reduction at minimizing very low
frequency noise.

When averaging is on, there is an indicator in the lower right corner of the analyzer’s display. The
display is in the form
Avg
x
where is the averaging factor for measurement channel 1, and
is the averaging factor for measurement channel 2. If only one measurement channel is on, the
averaging indicator only displays that channel’s averaging factor.
