TEK 7404 4GHZ scope on ebay

(1/6) > >>

leafi:
First of all Im not the seller and have no relation or anything to them.

It is a tektronix CSA7404 20GS/s 4GHZ BW. Normally the 7404 series is over 10K on ebay but this one is currently really cheap. Im not sure if I should bid on it as a back up for my TDS7404. What do you all think. If anyone decides to buy this be aware you will need the tek adapters for anything you want to plug in. ie BNC or SMA or even a normal oscilloscope probe.

Has anyone ever cracked tektronix unlock codes? I would love to get the full memory depth out of mine. It really pisses me off when they charge the customer for the memory chips as part of the BOM cost then disable them and make you pay them 10K or more to enable them!

nctnico:
I'm quite sure the price will get close to market value towards the end of the auction. Then again this scope is intended as a communication signal analyser. There can be differences between a 'normal' scope. Regarding the unlock code: use a debugger to see what installing an upgrade code does. I think its just complicated enough so that someone who just knows how to use wordpad or regedit cannot unlock the extra memory.

krenzo:
Yeah, the price is going to shoot way up as the auction comes to a close.  Item Location: Beaverton, OR also indicates the seller is going to make a ton of money off of the sale as they bought it from the Tektronix surplus store.  A friend bought one of their 6 GHz scopes from the store there for about $300.

Umm, this scope is being sold by the Tektronix surplus dept.

The last one they sold on eBay went for $3550, but that was a real TDS7404 rather than a CSA7404.
