50MHz USB pen-style Frequency/Period Counter

USB Tester More Like This USBcount50 is a new concept in USB Frequency Counter products. PC based frequency counters deliver many user benefits including flexibility, ease of use and economy. They are an invaluable tool during design and debug of digital circuits and can be used to quickly to verify generated frequencies, pulse widths and duty cycles. USBcount50 combines very small form factor with high performance normally associated with much larger bench type products. Power for the Frequency Counter is provided via the USB interface connector, further simplifying the user experience. The input is galvanically isolated from the USB bus/PC ground meaning that signals from unit under test do not need to be referenced to the ground of the PC. USBcount50 is small enough to be carried in a shirt pocket or laptop bag. Up to 4 units can be snapped together to allow relative time measurement between channels e.g. time between pulses from different sources can be measured. Relative time measurements have resolution of 20ns.
