Using Excel and VBA with DSA800 spectrum Analysers

Microsoft Excel and Visual Basic for Applications (VBA) is a great way for engineers who need to analyse and archive data from their instrument to access the data without deep programming skills.With this in mind, we have created VBA examples for some of our instruments including this one for Spectrum Analyzers including the DSA800 family.Download the example file hereUsers should also install Ult...

NRSC AM Measurements using a DSA

The Rigol DSA815 Spectrum Analyser has a built in Limit Line test that can be a convenient way to measure and compare spectral power against specific masks used for various signal types. One common test is NRSC Amplitude Modulation (AM) test. In this example, we are going to use the Pass/Fail mask to evaluate an AM Channel vs. limits set up by the National Radio Systems Committee (NRSC). Here is...

How do I measure FM Deviation with a DSA?

General purpose spectrum analysers like the Rigol DSA series can be used to test the deviation of an FM signal. In this example, we are going to measure the FM deviation of a 10MHz FM signal with a DSA815. This is Rigol’s 1.5GHz spectrum analyser. NOTE: We are starting from Factory default settings. See the User’s Guide for the instrument you are using to learn more about restoring factory d...

What is the fastest sweep time in Zero Span mode with a Spectrum Analyser?

The Rigol DSA815 Spectrum analyser features a zero span mode that can be helpful in observing modulated signals. In swept mode, the detector of the analyser is sweeping across a span of frequencies at a predefined rate. The display then shows the amplitude vs. frequency of that swept scan. In zero span mode, the detector is fixed at a selected center frequency with a bandwidth set by the resolut...

Defective UltraSpectrum display with DSA800 series

If you experience a defective UltraSpectrum display while connected to a DSA800 series spectrum analyser the most likely cause is due to a UltraSpectrum software version mismatch. Software version 00.01.00.27 corrects the issue and can be downloaded from the blue Downloads tab at:https://www.rigolna.com/products/spectrum-analyzers/dsa800/Here is an example of the UltraSpectrum display using an i...

How can sweep time effect my Spectrum Measurements?

Spectrum analysers can be used to observe modulated signals. But, some settings may have to be adjusted to observe the signals clearly.In this example, we are going to show how the sweep time and selected detector type can effect the displayed data.Source: Rigol DG4062 60MHz Dual Channel Arbitrary waveform generator.Signal: Sine wave, linear sweep from 230KHz – 270KHz, Sweep frequency of 120Hz...

EMI Test System Software Getting Started Guide

The Rigol EMI Test System Software is designed to make precompliance scanning with a Rigol DSA family of Spectrum Analyzer easy. This Note is an addendum to the Software User’s Guide. We will set up a prescan, create an amplitude correction table, set limit lines, and perform a final scan. Initial Setup: - Download the latest version of UltraSigma and the EMI Test System Software from t...
