 Network Analyzers using S2VNA software

This section describes ways to optimize the measurement:

Narrowing the IF bandwidth of measurement receivers increases the signal-to-noise ratio and extends the dynamic range of measurements. This increases the value of the sweep time. For a detailed description, see IF bandwidth.

Averaging allows to increase the signal-to-noise ratio and extend the dynamic range of the measurements. Averaging does not increase the value of the sweep time, but the averaging result is complete after N sweeps, where N is an averaging factor. For a detailed description, see Averaging.

Smoothing does not change the dynamic range of the measurements but reduces the noise emissions of the signal. For a detailed description, see Smoothing.

The figure below shows an example of applying different optimization methods to the signal: the IF bandwidth is reduced by a factor of 10, averaging factor is set to 100, and smoothing is applied with an aperture of 2%.
