Title: Marconi Spectrum Analyser TF2370
Post by: gergard on April 18, 2017, 02:55:36 pm

I have a spectrum analyzer Marconi TF2370 not working, power on is ok, but it certainly has some problems, there are known faults in the power supply?

The defect is, graticule ok, line present, noise none, scan locked, output square vawe 10MHz (25) is present, amplitude1,5Vrms, counter is on but locked at 04800000.0
If I connect 10MHz out (25) to the input (24), set sweep in manual mode and move bright line position, I see something.
