So I have a Tek DPO4034 that has a broken shaft on the pan/zoom control. The encoder is quite complex and it cannot be repaired. I explored drilling the shaft down the center and using a screw, but it's not built in such a way where that's possible at all.
I'm not sure if this is a custom part or not; I suspect that it is, but I'm hopeful that it's not.
The only marking on it is J07J28. At least I think that it's a zero.
Has anyone ever seen one of these encoders or know who the manufacturer is, or whether it's custom made for Tek?
I'm pretty sure that Tek will not sell the part, and offer only a replacement board for big bucks. These days, I guess they figure if soldering is required, the end loser can't fix it...
Thanks!
I bought a TDS3014B with a broken encoder shaft. I managed to buy a damaged TDS3014B PCB with all the encoders in place. The shaft part of the encoder was attached to the PCB with 'hot melt' plastic rivets. So, its not difficult to remove the shaft half of the encoder. The other half of the encoder is actually part of the PCB. I swapped over the plastic encoder and the problem was fixed.
Here is a relevant patent......
http://www.google.com/patents/US6542089and Tektronix supplier is here....
http://www.bourns.com/products/encoders/contacting-encodersTek sources from Bourns with the condition that Bourns are restricted to Tek sales. So these parts are proprietary, you will not be able to source the individual encoder.
Your best chance is to find somebody who is parting out a DPO4034.
As an alternative option you can model the part and 3d print a replacement.
I don't have the resources for that, unfortunately. Also the shaft is missing...
I may end up buying a DPO2012 front panel from Tek. They want $252 for it!
If you do the modeling I would be happy to print it for you. Basically no filament goes into this since it is so small. During my printing down time or color changes I would be happy to knock one out for you.
As I said, I don't even have a part to model from, and, additionally, don't have the software or knowledge to do it anyway. I do appreciate the offer, though...
I'll probably bite the bullet and buy a DPO2K front panel PCB from Tek. $252 - ouch.
or if they have an part left
