Highest measurement performance and highest data throughput is achieved with LVDS stop inputs and LVDS serial outputs for each channel. Current saving operation is also possible with CMOS inputs and SPI readout. High configuration flexibility and unlimited measurement range cover many applications. They range from portable handheld laser range equipment to ambitious time-of-flight measurements of highest performance, as e.g. done in medical imaging applications. GPX2 operates without any locked loop technologies. GPX2 calculates all stop measurements inside, proportional to the applied reference clock. Combinations of best single shot accuracy of 10ps with lowest pulse-to-pulse spacing <5ns and maximum data throughput rate of 70MSPS per stop input are possible.
