Weeder Technologies Frequency Measurement cards with free Window's software

Most frequency counters measure the frequency of an input signal by counting the number of cycles that occur within an exact predetermined gated time period. This method has its flaws because the resolution is limited to the precision of the gate time and its divisions. Our low-cost Frequency Counter card that plugs into an RS-232 or USB port of a computer uses a more advanced approach. Instead of counting the pulses that occur within a predetermined gate time, it measures the exact time it takes for a significant number of cycles to complete and then uses the formula freq = count / time. This method greatly increases the precision and resolutions of 0.00001 Hz can be achieved.
