CMU200

(1/1)

elettronica52:
My cmu200 has the failed rf signal generator. The test loop of the inputs fails and also the fm deviation. Everything else works. It gives me no faulty module. I measured the signal at 13.8 Mhz in input rxtx is 20 mV. And there are the various modulations. I measured the output of the sma tx and there is only noise with a very low signal, of a few microV. I sent a 10 Mhz signal to the frontend module and it appears at the output.
Has anyone repaired this rxtx module?

Dear OM IZ2GGS,

take a look at MC-Forum
    https://www.mikrocontroller.net/topic/433164#new
Some experts for R&S device issues are available there.

Good luck

Some experiments with built in FMR6 (i815 chipset) Ethernet adapter.
Success!

How you load the  C:\NET\NET.CFG during boot?
Via Autoexec.bat?

I loaded via autoexec.bat file manager Volkov Commander (clone of Norton Commander) and then with the help of it did anyting I want.
Generaly, you do not need to do any chages in autoexec.bat. In the original application you can press Alt-F4 and exit to DOS prompt and do anything you need.
