Product specifications

The key measurement setup parameters of a spectrum

analyzer are:

• Frequency

Adjust the frequency range measured

• Span

Adjust how closely you look at the signal

• Amplitude

Adjust the view of the signal’s level

A typical spectrum analyzer measurement procedure

contains the following three steps:

1. Tune the center frequency of the analyzer to the signal

of interest.

2. Adjust the span to zoom in on the signal of interest.

3. Adjust the amplitude to give the optimum view of the

signal.

In this demonstration, we will set signal generator to

output a signal to N934xC HSA with an RF cable and set

these parameters.
