GFT2005

  • Five Channel Time Interval Meter: one Start and four Stops

    It has five channels: Channel 0 is used as the “Start” time reference for channels 1-4 being “Stops” events of the Time Interval measurement.

  • 10 MHz sample rate per channel

    The instrument uses an internal 10 MHz oscillator or an external very stable 10 MHz source.

  • 100 /1000 Mbit/s Ethernet interface

GFT2005

The GFT2005 is a very precise Time Interval Meter. It has five channels: Channel 0 is used as the “Start” time reference for channels 1-4 being “Stops” events of the Time Interval measurement. Each channel can measure the time of the rising edge of one electrical input, to 13 picosecond resolution with > 100 second range. Time Interval samples can be automatically processed to provide Mean, Max, Min and RMS/Jitter.

The instrument uses an internal 10 MHz oscillator or an external very stable 10 MHz source.

The Instrument offers 4 GPIO (digital bi-directional signals) under software control for communication to external equipment.

The GFT2005 is a low profile 19″, 1U rack instrument with Ethernet interface.

The instrument as a built in Web server that provide an easy remote control via a standard Web Browser. “Control panel Web page” from embedded web server provide an easy method to:

  • Configure settings for each channel and Control operation and status of the instrument
  • View the measurements (value and graphic form)
  • Save the measurement in your file computer.
