Preface
Preface
This manual provides tutorial examples of how to use the RSA6100A Series Real-Time Spectrum Analyzers and RSA5100A
Series Real-Time Signal Analyzers to take measurements in different application areas. To work through these examples on
your instrument, you can use either the sample data files provided on your hard drive or a live signal of your choice. If you
use your own signal, you need to reset the instrument to match your signal’s parameters.
NOTE. You can use the mouse, keyboard, and touch screen to perform all of the tasks in this manual. Additionally, you can
use the knob and buttons on the analyzer front panel as shortcuts to perform some of the tasks.

aking a Basic Spectrum Measurement
Application 1
You can operate y our analyzer like a conventional spectrum analyzer. The following example leads you through basic
functions of frequency, span, and shows y ou how to make amplitude and frequency measurements with markers.
NOTE. The following examples use the RSA6100A Series analyzers for examples. The RSA5100A Series operates
identically except for a few differences on the front panel. Where these differences affect these procedures, they are
called out.
1. Push the front-panel Preset button to set
the instrument to the default settings.
The following steps set up the appropriate
measurement parameters for the sample
signal.
2. Click Freq in the application menu bar
and type in 2GHz.
2 GHz is the frequency of the saved
signal that you will recall in a later step.
Enter the value with the front-panel
keypad or an external keyboard attached
through the USB port.

: Measuring Channel Power and Adjacent
Channel Power
The RSA6100A and RSA5100A analyzers can take channel power, adjacent channel power, and multi-carrier channel
power measurements. This application demonstrates the settings used for taking channel power and adjacent channel
power measurements.
1. Push the front-panel Preset button to set
the instrument to the default settings.
Set up the appropriate measurement
parameters for the sample signal.
2. Ensure that Freq is set to 1.5 GHz.
