Spectrum Analyzers

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

Tekbox put together a nice application note on immunity testing using a TEM cell and a SIGLENT SSA3000X spectrum analyzer. TEM cells are specialized hardware enclosures that can provide high electric fields and also do offer some shielding from environmental RF. If you are having immunity issues, this note may provide some helpful information and guidance. … Continued

Attenuators are elements of an electrical circuit that are used to decrease the amount of power delivered to the next stage of the circuit. An ideal attenuator would have a flat frequency response, that is, it would decrease the amplitude of all input signals equally, regardless of the frequency. In this note, we are going to … Continued
