The EE Electronics ESLA201A 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, 1ACH (TODO: not verified on hardware) will be used unconditionally.

See EE Electronics ESLA201A/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.

The USBee AX software controls the unit through a combination of command messages, and firmware patched for sample rates etc. downloaded before each capture. For this reason we have abandoned efforts to decode the protocol, and are working instead on fx2lafw — a replacement open source firmware for the device.
