[time-nuts] TFL Rubidium Standard

[Euclides Chuma]

Hi,

I bought a TFL Rubidium Standard model TF4030B and the signal generated 
if of 5 MHz.
This equipment is good? The TFL is a good company? The 5 MHz signal can 
turn into 10 MHz? Someone have the documentation about this equipment?

Thanks for the help.

Best Regards
