USBee DX Pulse Counter
This section details the operation of the Pulse Counter
application that comes with the USBee DX.
The Pulse Counter is used to count the number of cycles or edges that
are detected on up to 16 of the digital lines.
Below you see the application screen.
To start counting the pulses or edges on the signals press
the Start Puls Counting button. The
pulses are counted and the current range of pulses is displayed. In this case the system is counting all
pulses down to 166.7nsec wide.
You can use any of the 15 lines as a gate to enable the
counting during specified times. For
example, you can count pulses only when Signal 0 is high by setting the Signal
0 Gate to High. Pulses that occur when
Signal 0 is low are not counted
