Monitor Spectrum (Frequency Domain) Measurement Concepts

Purpose
The Monitor Spectrum measurement provides spectrum analysis capability for
the instrument. The control of the measurement was designed to be familiar to
those who are accustomed to using swept spectrum analyzers. The primary
use of Monitor Spectrum is to allow you to visually make sure you have the RF
carrier available to the instrument, and the instrument is tuned to the
frequency of interest.
Measurement Method
The analyzer sweeps the LO to generate a heterodyned IF signal which can be
detected for the purpose of analyzing the signal content of a range of
frequencies. The x-axis of the display is frequency, the Y Axis is amplitude.
