First of all, I am using Deepl translation. Some sentences may be difficult to read. My apologies.
I recently purchased a TDS7104.
I found a junked and battered TDS7104 and decided to fix it up and use it.

Parts purchased, made, etc., and the fix is complete! It is now operational.
TDS7000 Topic folks. Thanks.
https://www.eevblog.com/forum/testgear/tek-csa7404-repair-project/However, a problem arose. I executed a command to address an error I was getting in the debug terminal output.
command: calConStatus = cc_init(1)
I then rebooted and was pleased to find that the error was gone. However, when I ran Diagnostic, there was a 521 error in Factory Cal Integrity.
I was stumped, apparently I had deleted the calibration data.......

In my search, I found a dump of the calibration data on the ACQ board in a post in the TDS7000 topic.
https://www.eevblog.com/forum/testgear/tek-csa7404-repair-project/msg3144050/#msg3144050I tried writing it to the EEPROM and it did indeed remove the error.
However, the error is gone, but the calibration is still off.
Therefore, I am looking for someone who has the Fluke 9500B needed for the calibration.
I have looked for a repair company in my area of Japan, but none of them have the 9500.
They seem to have the old school 5500/5700 though.
Maybe they don't have it because I need 5 active heads 9530 and it costs $8000 on ebay?
Or you can give up and
1) Use the dump as written, or
2) Buy a new TDS7104 ACQ board.
Hmmm, the calibration doesn't seem to be off, but I don't feel good.
But I also want to taste the TDS7104, which is more powerful than the TDS754D I was using before, as soon as possible.
What would you guys do?
Anyone who has a Fluke 9500 (or 9500B) and 5 active heads 9530, I'll pay you and you can calibrate this poor TDS7104.
I do have software for calibration, downloaded from Tek.com.
We can pay up to $1000. Shipping from your place to mine + work fee.
Or the one who is willing to rent it to me for $500 a week.
How do I get them to trust me?
Thanks for reading. I have something I want to build and sell, so I'll be using it as is for a while.
Please reply if you have 5 9500 and 9530 and are willing to adjust or loan TDS7104.

I got a rough estimate from Tektronix Japan for $2300(US).
It's not an amount you can pay in the hobby.
