I unfortunately don’t have any documentation on this option but you might gain a little information by going here: https://groups.io/g/TekScopes/topic/dc508_help_with_photos_option/30289354 Greg

Indeed I do. Those are actually made by at least three different companies: Tyco/AMP, Hirose Electric and Molex. They're 1.27mm pitch on the contact spacing, and DigiKey has a generous selection at

Seems close (not significant differences) with 1-1734099-0, used in TDS3000. https://www.ebay.ca/itm/163591113538 TT

Does anyone happen to have a PDF of the instructions that accompanied the Tektronix 040-0789-00 field modification kit for adding Option 7 to the DC-508 or DC-508A counters? Bruce, KG6OJI

Where I wrote "pin #4 of U1560" I should have written "pin #9 of U1560"; I mis-traced the long parallel tracks on the schematic. -- Jeff Dutky

Shouldn't be a factor, adding an extra display that exactly replicates the internal display is just paralleling signals. If the external display could be written to separately, then it would be CPU

Soon as I figure out how to send you a photo I'll get it on the way!

I don’t own a TDS380 so I don’t have a basis of comparison, but it looks completely normal to me. I would expect measurements to consume some CPU horsepower, with a corresponding slowdown or

Any thoughts? Normal?

Have a look at TE part number 1-1734099-0. Not sure if anyone has stock, but Mouser's minimum buy is 1 piece (when they have them). Dave Casey protonmail.com@groups.io> wrote:

This is correct on a DSA 602a there are 2 distinct modes of operation straight sampling and equivalent time sampling. You can clearly tell which mode it is in based on how long it takes to build a

Hi all, as part of repairing a couple TDS600/700 series scopes, I need to source a few connectors. Does anyone know what this connector is and where I can find some? I can't see any markings on it to

The 106 can generate square waves with a frequency between 10Hz and 1MHz so even a 10MHz 'scope can show their amplitude. It just cannot show anything even resembling the signal's rise time. I guess

The DSA602A should work though it is being pushed to the practical limit. It will not be able to do amplitude measurement based on the -3db limit and being in the upper range of the falling curve.

I agree, especially because digital 'scopes usually have a much steeper fall-off than (mostly Gaussian) analog 'scopes. That also explains why the familiar 0.35 factor for BW / rise time conversion

Hi David, Reading back my message, I realized that it could be seen as criticism of what you wrote. It wasn't meant that way and I apologize if that was how it came through. In fact my reason to write

Nice explanation. In a way, modern DSO are pretty much somewhat similar to older sampling scopes. I’ve always heard that you need 1GS/s for every 100Mhz. Not really the topic, but since it’s

Hi David, There seems to be some confusion here: The sampling 'scope that the 106 SM refers to is not a digital 'scope, of course. "Analog sampling" used to be the only way to achieve really high
