50MHz USB pen-style Frequency/Period Counter

Features

• USB Interface
• Comes with Java software for multiple platform compatibility
• Measures frequencies from 0.1Hz to 50MHz. Uses reciprocal counting for low frequencies
• Pulse width and duty cycle measurement with resolution of 20ns
• 8 Digit display
• Data logging capability
• Input level programmable to 1.8V, 2.5V, 3.3V and 5V which supports most popular logic interface standards. Input is over-voltage protected
• 1Meg // 20pF input impedance
• Choice of integration times to suit resolution and readings/sec required
• Output is galvanically isolated from USB port to 300V Cat II
• 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
• Can be snapped together with a USBscope50 to form part of a suite of instruments
• Body is approx. 75mm x 31mm x 17.5mm

Description

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 .

The USB interface has developed into probably the best and most widely implemented PC peripheral connection method and is a natural choice for the Frequency Counter.

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.
