In this note, we discuss EMC pre-compliance test parameters and how different settings affect your measurements. There are also sensitivity considerations and tips for the protection of the spectrum analyzer during tests.
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
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
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
Here is a brief code example written in Python 3.4 that uses a socket to pull a display image (screenshot) from a SIGLENT SSA/SVA analyzer via LAN and save it to the local drive of the controlling computer. NOTE: This program saves the picture/display image file in the same directory that the .py file is … Continued
The SIGLENT SSA3000X series of spectrum analyzers have an on-screen peak detection that can be used to easily show the peak values in a Configure the instrument span, RBW, and amplitude to capture the signals of interest Send “:CALC:MARK:PEAK:TABL ON” Send “:CALC:PEAK:TABL? “ to return the peak table data Here, we show the displayed peak table and … Continued
This LabVIEW VI (version 2018) provides a simple platform to begin creating LabVIEW programs. You can download the VI here: VISA_IDN.ZIP In this example, the user can: Select the connected instruments from the VISA Resource List drop down menu: NOTE: USB devices will automatically appear. For LAN connections, you will need to add the device. … Continued
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
Many products have Kensington, or K-lock slots to help provide a location to secure a cable lock or other device to help prevent theft. Some products do not have locations for cable lock connections. In this case, we recommend using a special glue or physical attachment system to secure the cable to the case of … Continued
