There are a few used test instrument models that I’m familiar with the common problems. I moved onto the higher end, big ticket items so I wouldn’t bother acquiring them anymore.
Nonetheless, it hurts to see a piece of good equipment going to landfill. I’d be happy to repair the following models at a moderate rate (materials included, no fix no pay) below if anybody is interested:
- HP 6515A power supply: $400 for a problematic unit, $300 when you send in a good one for preventative recapping (the capacitors are from 1970s! They are dying.).
- HP/Agilent 54600 series oscilloscope: display got squeezed ($200), unit losing memory/time ($200), blown input channels due to excessive voltage ($300 for 1 channel + $100 per extra channel), unstable/cannot trigger ($500).
- HP/Agilent (Older, non-Megazoom) Infiniium series: replacing OS hard drive ($250), cannot calibrate certain channels ($400 for 1 channel + $100 per extra channel).
- HP/Agilent Infinium 5483X and above: refer to 54830 series post.
- TDS 500, 600, 700 series oscilloscope: SPC fail without other symptoms ($500), Acq/Attenuator fail ($600), Proc board fail ($400), Color screen bubbled ($500), Cal initialization failed ($300), upgrading all possible software options ($200, free with any other service).
Contact me at 650-804-5024. All units must be delivered to Irvine, CA for service (and shipped back/picked up) at requester’s cost.
