The HT USBee-AxPro is a USB-based, 8-channel logic analyzer with up to 24MHz sampling rate, with 1 additional analog channel (3MHz analog bandwidth).

It is able to switch between USBee AX-Pro, Salea Logic and Altera USB blaster mode via a button. When pressing the button the USB VID/PID changes.

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

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

See HT USBee-AxPro/Info for some more details (such as lsusb -v output) on the device.

Notes:

  • Some devices have R2 = 66.5Ω (instead of 66.5kΩ), this basically limits the range to -3.3V — +3.3V.
  • TLC5510 is used with ~3.3V "reference" from LDO output which is both out of the allowed range and is a major source of inaccuracy.
  • Some devices (probably those that do not have U5 populated) produce bogus min and max spikes when measuring certain voltages, this can probably be remedied by adding small (on the order of 10s pF) capacitance to U5 Vcc and GND pins or to the ADC CLK line.

Pin mappings

The FX2 CTL2 and PD0..7 pins are mapped exactly like the HT2013 V5.00 version. The TLC5510I OE# pin is tied to GND.

Protocol

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