Agilent Keysight 33500B Repair - looking for photos
« on: March 17, 2023, 04:56:47 pm »
Hi. I'm in the middle of a 33509b waveform generator repair. I snagged the unit for a reasonable price and it seems that a previous technician was a little tip happy with his coffee.  :=\
Besides the very sticky residue all over the front panel PCB, I noticed that the CMOS battery area looked a bit compromised.
There looks to be a voltage sense resistor missing near the positive 2032 battery trace and the bottom half of the battery tray has sheared off the board.

If anyone has high resolution photos of the front panel PCB, I would be very grateful.
Double points if anyone knows what the value of that resistor is.

Many Thanks!

when i measure the resistor (the print on it says 53A) i see 348 ohms.
I think the value is not 100% correct as I measured the resistor in fitted position and battery in place.

I think you measured the resistor correctly:
