Finally finished my CRT to LCD conversion on my #HP #8594E spectrum analyzer. The LCD is a little larger and much brighter. Under the hood it uses a 5,6" LCD, GBS8200 video converter and an #esp8266 with gbs-control to convert the HP video signal.

Two weeks ago I got this broken #HP8594 #spectrum #analyzer at #HAMRADIO fair in #Friedrichshafen
After a long night, multiple filter alignments and my own "interpretation" of the service manual, the unit is back alive⚡
Now I need a GPIB adapter & sig gen as well😝

Do you have experience with HP gears? I have a 8594E that will not pass calibration when one of its addon card is installed.
