The Stanford Research SR620 Universal Time Interval Counter measures time interval, frequency, period, pulse width, phase, as well as rise and fall times.
- Measures intervals up to 1000 seconds in ±TIME, +TIME, or EXTernal (with or without holdoff) arming modes
- Measures frequency over 12 orders of magnitude
- 0.001 Hz to 1.3 GHz frequency range
- Preprogrammed frequency measurement gates include 1 PERIOD, 0.01, 0.1, and 1.0 second, or EXTernal
- With an external trigger, program your own gates from 1 µsec to 10 msec
- START/STOP inputs range from -5 to +5 Volts and may be terminated in 1 Mohm or 50 ohms
