Measuring Filter Characteristics Using the SSA3000X Plus / SSA3000X-R / SVA1000X Spectrum Analyzer

June 22, 2021

A filter is a universal, two-port, frequency-selective device used in a wide variety of electronic circuits and applications. A low-pass filter is one that passes signals with a frequency lower than a certain cut-off frequency while attenuating the higher frequencies. Low-pass filters are often used in radio transmitters, audio devices, and communication systems. They can … Continued

Inter Modulation Distortion (IMD) testing

February 17, 2020

Two SIGLENT SDG owners and Amateur Radio operators and frequent experimenters, Steve Ratzlaff AA7U and Everett Sharp N4CY, got together and built a very thorough test procedure for testing Intermodulation Distortion (IMD) on a Loop Amplifier using a SIGLENT SDG2042X generator and SSA3021X spectrum analyzer. IMD is an important test for verification of audio amplifiers … Continued

Build FM NRSC masks for SIGLENT SSA3000X/SVA1000Xs using a Python script

February 13, 2020

Many broadcast applications require monitoring a transmitter and observing the output amplitude vs. frequency. For FM radio applications, a common mask is defined by the National Radio Systems Committee (NRSC) and is commonly referred to as the FM NRSC mask. A very helpful SIGLENT owner, Dan from Alabama Broadcast Services, LLC, built an FM NRSC Mask … Continued

August 6, 2019

Introduction The SIGLENT SSA3000X, SSA3000X Plus and SVA1000X products are based on a similar swept superheterodyne spectrum analyzer platform and have very similar starting prices. There are quite a few similarities, but also a few differences that could affect the end results for particular applications. The table below compares the major specifications and the comparable … Continued

DIY Spectrum Analyzer Input Protection

May 24, 2019

Spectrum analyzers like the SIGLENT SSA3000X and SVA1000X series are extremely useful instruments that can provide invaluable insight into broadcast signal performance, transmitter troubleshooting, and interference as well as RF device characterization and EMC testing. But, like other spectrum analyzers, they are very sensitive and can be damaged easily, if the proper precautions are not … Continued

Programming Example: List connected VISA compatible resources using PyVISA

February 19, 2019

PyVISA is a software library that enables Python applications to communicate with resources (typically instruments) connected to a controlling computer using different buses, including: GPIB, RS-232, LAN, and USB. This example scans and lists the available resources. It requires PyVISA to be installed (see the PyVISA documentation for more information) *** #Example that scans a … Continued
