CNT-91R

Pendulum Instruments

400 MHz, 50 ps Timer/Counter including Rubidium Time Base

The Pendulum CNT-91 zero-dead-time counter features continuous data streaming of measurements over GPIB/USB during, not after, measuring; creating a dynamic measurement/analysis system, a fi rst in the counter industry. The CNT-91 is a unique frequency Analyser, outperforming any universal timer/counter.
