Agilent 53132A Counter Repair (FIXED and Upgraded)
SoundTech-LG:
I got VERY lucky. Broken fusible trace at CH1 BNC input...
Working again.
HighVoltage:
Congratulations !
Now make sure the BNC connectors are good and stiff mounted in the housing.
SoundTech-LG:
No "adjustments" to the BNCs are possible. They are soldered securely to the main board, pass through the tight fitting plastic front panel openings. That's it. It is what it is...
HighVoltage:
On one of my counters, the BNC wiggled inside the housing. So, before inserting it, I added a very thin layer of shrink-tubing on the BNC to make it tight.
May be not all counters have this issue with space between BNC and housing.
SoundTech-LG:
yes... the plastic is tight around the BNCs... no room for the thinnest heatshrink ever manufactured.
Which makes me conclude this was never a mechanical issue at all. Purely an overload condition that popped the fusible portion of the trace. If you look closely under magnification you can see the fusible spots along the input trace. Thank you HPAK.
