Counter

• USB4711: one 32 bits counter with max to 1k input rate
• USB4711A : channel 0 is a 32 bits event counter with max to 1k input rate or 0.1HZ~10KHZ frequency measure. channel 1 is a  24 bits counter with 24M base clock provides pulse out function .

Note:

1. The USB chip on your system may have a limitation on the number of USB devices it supports. Normally, only five USB-4711/A devices can be supported.

2. The maximum sampling rate under Full Speed mode (USB 1.1) is 25kS/s.
