I would appreciate it if you could get information about the reason for this error

Dear Customer,

Ticket 507061 has been resolved.
The resolution proposed is:

Dear David

The testpoint for the 3rd local oscillator in the 3rd mixer stage of the TX board delivers a Voltage of 1.02V which is too high. Limit is 0.2V.

Reason for this, perhaps aging or defect of a component.

But we cannot repair the CMU200 any more.

 

With best regards

Winfried Jansen

First of all, thank you very much for the response
I don't need a fix
My field is repair and calibration of laboratory equipment
The whole problem is that you are one of the only companies that cannot find a schematic for your products .
This definitely makes me avoid purchasing your products in the future.
the right to repair
This is something that every company should respect in our day.
And it's a shame that you are in the same category as Apple

Greetings David Azulay
