Systron Donner 6016 Microwave Frequency Counter
18GHz Frequency Counter (18,000,000,000Hz)
A Nice 1970's digital frequency counter for counting between 20 Hz and 18 GHz.
Nine nixi tube display, with fast, slow or hold display, with resolution to 100 Hz when measuring 18 GHz.
Fully working and accurate (can only test to 3GHz). I believe is fitted with a "Standard" oscillator, which has a 72 Hour warm up time, so tested using my 1MHz reference source)
(Marconi Signal source used to demonstrate, is not a precision source, using a cavity tunned gun diode)
