Hi, I have for sale a used CNT-91 with options 10 and 30
High stability oven oscillator as time base and 3GHz input C
Channels A&B run up to 400MHz
Single Time stamp resolution is 35ps
Got it from a cal lab that went out of business.
Time base and voltage were "factory" calibrated last year.
Cost of a new one is around 5600 USD
I can give this one for 2900$
If you are interested let me know.
