SUPERIOR PERFORMANCE The GT210PXIe-1 Time Interval Counter is an improved version of the GT200-10, which is currently in use in thousands of applications ranging from satellite tracking to monitoring of atomic clocks. They include all of the functions normally found on premium counters: Time Interval, Frequency, Period, Totalize, Ratio, Time Interval Delay, and Pulse Width. Unlike many other boards of its kind, these instruments deliver worry-free results, and their inputs are high instrumentation quality, with the sensitivity and damage protection features common to all high quality counters. GuideTech’s next generation Time Interval Counters, a smaller foot-print and much more powerful instruments to address your current and future applications. With easy expansion and modular capabilities, GuideTech offers a wide range of CTIA solutions in PCI, PXI, and as an Integrated Systems. Achieve impressive performance and accuracy with GuideTech’s Time Interval Counters product line. Up to 2.7GHz with noise floor of 15ps.

GuideTech’s GT210PXIe-1 3U form factor, meets industrial standard chassis with an expandable platform, achieving optimal test system with optimal cost. The ability to precisely resolve frequency and time yields both increased accuracy as well as reduced measurement time. For example, with the GT210PXIe-1 you can determine any frequency to 0.01 part per million (eight digits) in just 1 mS, and resolve each time measurement to 8pS. Couple that with 2300 measurements per second, one of the fastest rates available and you can acquire more data in a single second than a typical GPIB counter can in one minute! Faster measurements and higher resolution, along with built-in statistics functions give you a more thorough analysis of your signal. Standard deviation, peak to peak jitter, or a graph of the measurements are available at the push of a button.
