Hi, I've got a similar problem with a TDS724 - it seems to be very slow to respond to the front panel controls. Denis if you are still around, did you manage to solve your problem? Meanwhile I'll chec

Hi Jim, Did you ever solve the trigger problem with your TDS6604, as I got one here with the same symptom? All of the diagnostic tests pass except SPC. This unit had a flat NOVRAM battery - not sure i

Hi Flyte, I've got a TDS6604 here that I'm working on - I'd be interested to know the differences in the Acq. boards. Mine has a trigger problem and SPC fail. Maybe we can share notes? Regards, - Guy.

Hi Jim, I found the cause of the trigger problem with my TDS6604. It was the trigger chip - luckily we have an SMD repair station at my work -> they are not too hard to replace if you have hot air. Th

Hi Flyte, I've managed to find the main fault with my TDS6604 - one of the trigger chips was fried, the infamous Tek # 156-8278-00 I've also managed to locate a couple of Acq. boards for TDS6604, but

I'm trying to restore a TDS6604 to it's former - hours of fun for the whole family! After a few setbacks (Overheating CPU and a flat battery on the PPC board) I have the scope working 99%. The remaini

Hi Charlie, I tried running SPC but it looks like the Acquisition board I have purchased is faulty. SPC fails and channels 3 and 4 are unstable beyond 2.5GS/s. I might re-visit the original Acq. board

Hi There, We have a scope at work with 80SJNB - I'll check to see if I have on CD - however it's pretty old (Windows 98). Also, you can download 80SJNB for Windows XP scopes from the Tek website. Whic

Hi again, I checked the CD I have at work, its the same Version (2.5.4) as the download on the Tek website... https://www.tek.com/oscilloscope/csa8000b-software/80sjnb-jitter-noise-and-ber-analysis-v2

ESD?

Hi Egge, I've repaired both types without drama. If the NVRAM is separate to the battery, check the leakage current and if necessary replace the NVRAM too. It's easier to de-solder than a DS1245Y-120

Hi Egge, I've not seen a TDS7000B Acq. board, so I can't comment. If you can send me a link to a hi-res image I can compare to the TDS7000 Acq. boards I have here. What bandwidth are you looking for a

Hi Egge, Yes it looks like those trigger chips were designed out on the B. However it seems like the B models are a bit more expensive. If you can't find a B Model at the right price, I have a NICE TD

Hi Egge, No, I've tried to keep this unit as original as possible ;-) It has the following options : 4M JA3 JT3 Regards, - Guy

I'm pretty sure the bandwidth on those models is determined by the Acquisition board. If you check the service manual I think you will find each model has a different Acq. board.

Hey Jacob, The first challenge is to get a Tek OEM Windows Install Disk, these are NOT available for download on the Tek site. Check the Windows label on the rear panel to find out what was installed

Hi, I've managed to get hold of a faulty DPO72004 at reasonable price. It has a dead PSU which is an Artesyn AFE1200 - 48V, 1200W. One seller on ebay is asking US$3999 for these PSUs which seems a bit

Hi Egge, Yes I saw those advertised last year, but they are now out of stock. I've opened up the PSU and some of the HV switching FETs have failed. Fortunately Digikey has stock, stay tuned. Regards,

Some progress, I replaced the HV switching FETs and the standby current limiting resistor. The PSU is now working and the unit boots. I don't have acquisition working yet, but this is a big step forwa
