How to observe demodulated audio from a spectrum analyzer

December 16, 2020

Viewing demodulated audio can be important when troubleshooting a transmitter.   In this video, I demodulate an FM radio station using a SIGLENT spectrum analyzer and view the output signal on an oscilloscope.

Distance-to-Fault cable testing with the SVA1000X

March 3, 2020

In this video, we use the Distance-to-Fault (DTF) function available on the SIGLENT SVA1000X Spectrum and Vector Network Analyzer instruments to test a few sections of coaxial cabling. DTF uses frequency domain reflectometry (FDR) to highlight impedance differences along a length of cable. This can be used to determine the distance to adapters, faults, and … Continued
