Have each of you looked into the condition of the SMD electrolytictoggle quoted messageShow quoted text
capacitors on your spectrum analyzers?
In the few examples of these spectrum analyzers that I have worked
on, I have found a number of problems:
1) focus string SMD 1M and 2M resistors that weren't properly
soldered due to a plating failure on the board.
2) a whole slew of SMD electrolytic capacitors that were leaking
3) dead lithium cells used for memory functions...
4) switching power supply capacitors that are high ESR.
If any of the solder joints around the SMD electrolytic capacitors
are milky white in color, rather than shiny and metallic, the
capacitors are leaking electrolyte.
