GB-4000 and MOPA connection

[Guest guest]

Hello,

I am a french therapist and i have bought a GB-4000 and a SR-4 about 2 years ago

at " Future Tech Today " .

I would like to purchase a M.O.P.A. to connect to the GB-4000.

I have some questions about that :

1/ It seems that some modifications have to be operated on the

GB-4000 to put BNC on the back. Is it true ?

2/ As i don't want to send my GB-4000 back to the U.S.A, could the

modifications be done in France and if yes, what kind of informations i have to

give to an electronic engineer for him to do the job ?

I thank you of taking time to read those lines and i wish you a

great day.

Best regards, Gerald TIlki
