Does anyone sell TDS460A nvram chip with options activated


Paul
 

Hello
I figure i can pop out my nvram chip and replace with a another that has the FFT option enabled.
Anyone sell these. If you have such chip in yours would you consider copying it and selling it to me.
The reason I ask it no Dos machines or nvram programmers or isa-gpib around here.

Thanks
Paba

You can find USB to GPIB interfaces for sale or there are designs to make your own using Arduino compatible hardware and software.

For some of the other TDS series enabling options is just a matter of typing in two commands by hand.

Hi Roger,
actually I have an USB based GPIB adapter, but without controlling Software to read/write I won't be able to do much. The only I GPIB SW I use with this is Pete Millet's package for the HP 8903 distortion analyzer. Embarking on a big DIY effort to figure out the commands etc.. not really in my skill set. That's why I was looking for "spare parts" approach of swapping chips.
Thanks

I had a very quick look around and it seems that upgrades on the TDS460A are enormously more complex than the 'type in two lines of GPIB commands' that works so well on the later models.

Best of luck,

Roger

Which GPIB-USB adapter do you have and what operating system?

Hey Roger,

out of curiosity, what did you find? All I found was mentions of options
software and this eBay listing (https://www.ebay.com/itm/312205219440).

I have a TDS874D for which the procedure is well understood, and I amused
myself at one point by adding the "Communication Mask Testing" option to
mine. It's not of any use to me, but hey, why not :).

Hi Siggi
Thanks for that ebay link but I’m guessing that envelope contains floppy disks. So we are back to a Dos machine, isa- Gpib to talk to the unit a reprogram it etc. My tds460a doesn’t have a floppy reader.

Still think the easiest is to replace the nvram chip with a copy of one that is unlocked. There is a YouTube video on this approach.

Guess it was a long shot but figure someone here would have an unlocked unit and nvram programmer or that Tek spare parts vendors would have some.
