The Sysclk AX-Pro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel (theoretically 2, but only one of them can be used at a time; 3MHz analog bandwidth).

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

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

Note: fx2lafw currently doesn't support switching between the two possible analog channels, ACH2 will be used unconditionally.

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

Hardware

The analog channels are multiplexed by relay or solid-state IC to one ADC.

Protocol

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