XZL Studio AX

The XZL_Studio AX 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, 1ACH (TODO: not verified on hardware) will be used unconditionally.

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

Protocol

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

Resources

  • EE Electronics ESLA201A - the same circuit (from firmware's point of view). PCB has been copied and altered, same silkscreen labels. No electrolytic caps, no resistive trimmers, larger screw-hole-keepouts, no cap on pin 13 at U10, no U13 (second MAX1044/ICL7660). Has extra button inside the box!
