The XZL_Studio AX 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, as is the independent trigger.

See XZL_Studio AX/Info for some more details (such as lsusb -vvv output) on the device.
