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 TX6 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 XC6SLX9, 9,152 logic elements (family overview) (datasheet)
- USB interface chip: Cypress CYUSB3014-BZXI (FX3) (datasheet)
- ADCs: 1x Exar CDK8307B (datasheet) (seems to have same I2C reg mapping than HMCAD1100 used in Saleae Logic Pro 16)
- 32Kbit I2C EEPROM: 24C32A (datasheet)
- 6x amplifiers: Analog Devices ADA4891-4 (datasheet)

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 !
