The GFT2202 is very precise time interval analyzer with low jitter. It has two inputs :one Start and one Stop.
Reading data represent the time interval between one start and one stop.
Trigger level and slope are adjustable on each input. The module uses a linear interpolation technique and an internal calibration to obtain very high accuracy. The module uses an internal 155MHz very stable oscillator or an external clock. A software interface is included with the Time Interval meter analyzer and allows the programming of sample number, triggering conditions and the reading of time interval measurement.
