The '''Sysclk AX-Pro''' is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels.

It is a clone of the [[CWAV USBee AX-Pro]].

In sigrok, we use the open-source [[fx2lafw]] firmware for this logic analyzer.

'''Note''': Only the logic analyzer functionality is supported so far, analog support is work in progress. 

See [[Sysclk AX-Pro/Info]] for some more details (such as '''lsusb -v''' output) on the device.
