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. - Uses an internal 10 MHz oscillator or an external very stable 10 MHz source. - Offers 4 GPIO (digital bi-directional signals) under software control for communication to external equipment. - Is a low profile 19″, 1U rack instrument with Ethernet interface. - Has 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. ##### [Features](#features-section) ##### [Specifications](#specifications-section) ##### [Tech Resources](#technical-resources-section) ##### [Downloable Resources](#downloadable-section) ##### [Price List](#pricelist-section) #### Overview ##### Applications - Time of Flight Mass Spectrometry - Lab / R&D Characterizations - Fluorescent Decay - Real Time, Time Stamping Description - ATE (Automatic Test Equipment) - Optical and Magnetic Disk Timing - Component Test - Variation in Pulse Timing #### Specifications - Five Channel Time Interval Meter: one Start and four Stops - 13 Picosecond Resolution - < 50 Picosecond RMS Jitter - > 100 Second Range - 10 MHz Sample Rate Per Channel - Common Gate Input - Input for External 10 MHz Reference - 4 GPIO Signals for Communication to External Equipment - Quick & Easy Control via “Control Panel Web Page” (only 10 seconds to connect your PC) - 100 /1000 Mbit/s Ethernet Interface - Compact 19”, 1U with Optional Mounting Flange ##### Shipping Information **Shipping Dimensions** 23 x 23 x 9″ **Shipping Weight** 18 lbs #### Technical Resources [ GFT2005 Datasheet](https://www.berkeleynucleonics.com/download/20708/?tmstv=1778700935)#### Downloadable Resources Downloadable resources such as datasheets, firmware, software, drivers and products manuals.
