The Saleae Logic Pro 8 is a USB 3.0-based, 8-channel logic analyzer with 500/100MHz sampling rate (at 4/8 enabled channels) and analog sampling support on all 8 channels.
It is part of the second-generation Saleae Logic series, which consists of the Logic 4, Logic 8, Logic Pro 8 and Logic Pro 16. See Saleae Logic and Saleae Logic8 for the predecessor products.
The case requires a Torx T9 screwdriver to open.
See Saleae Logic Pro 8/Info for more details (such as lsusb -v output) about the device.
Note: Saleae Logic Pro 8 support in sigrok should be considered experimental for now. Only the logic analyzer parts are currently implemented (analog sampling is not).
Hardware
- FPGA: Xilinx Spartan-6 XC6SLX16, 14,579 logic elements (family overview) (datasheet)
- USB interface chip: Cypress CYUSB3014-BZXI (FX3) (datasheet)
- ADCs: 2x Hittite Microwave HMCAD1100 (datasheet)
- 32Kbit I2C EEPROM: 24C32A (datasheet)
- 12x amplifiers: Analog Devices ADA4891-4 (datasheet)
- This list is not yet complete.
There are several testpoints on the underside of the PCB. It is not yet certain what these are for. There is no visible JTAG header.

Firmware
You can use the sigrok-fwextract-saleae-logic16 (sic!) tool to extract (from the "Logic" Linux binary; tested with the Saleae 1.2.10 software) the FX3 firmware and the FPGA bitstreams required for using the Saleae Logic Pro 16:
$ sigrok-fwextract-saleae-logic16 Logic saved 5217 bytes to saleae-logic16-fx2.fw saved 149516 bytes to saleae-logic16-fpga-18.bitstream saved 149516 bytes to saleae-logic16-fpga-33.bitstream saved 178702 bytes from 46 blobs to saleae-logicpro16-fx3.fw saved 178702 bytes from 46 blobs to saleae-logicpro8-fx3.fw saved 465028 bytes to saleae-logicpro16-fpga.bitstream saved 341160 bytes to saleae-logicpro8-fpga.bitstream
Copy these files to the directory where your libsigrok installation expects them (usually /usr/local/share/sigrok-firmware) and they will be found and used automatically by the libsigrok saleae-logic-pro driver.
Note that sigrok-util (commit 20e302a2) only works Saleae Logic software up to 1.2.10 !
