The SysCLK USBee AX Pro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, and with 2 additional analog channels. Analog channels are multiplexed by relay or solid-state IC to one ADC.

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 -vvv output) on the device.

Protocol

Since we use the open-source fx2lafw firmware for this device, we don't need to know the protocol.
