ASIX SIGMA internals.

The ASIX SIGMA is a 16 channel logic analyzer with sample rate support up to 200 MHz and with 256 Mbit on-board memory.

It is supported by sigrok, and the necessary firmware files are generously provided by the vendor for distribution. As a result, the SIGMA works out of the box with sigrok. Trigger support has been implemented in 100 MHz and 200 MHz modes for rising/falling edges. Trigger features at lower sample rates are far more advanced and will be supported later.

Samplerate Number of probes
200 kHz 16
250 kHz 16
500 kHz 16
1 MHz 16
5 MHz 16
10 MHz 16
25 MHz 16
50 MHz 16
100 MHz 8
200 MHz 4

See ASIX SIGMA/Info for more detailed information on the device.

Firmware

The firmware files (FPGA bitstreams) for the ASIX SIGMA have been provided by the vendor under a license which allows redistribution, and are available from the sigrok-firmwares repository:

$ git clone git://sigrok.git.sourceforge.net/gitroot/sigrok/sigrok-firmwares

In order to use the ASIX SIGMA in sigrok, you need to copy the firmware files to the correct sigrok directory, /usr/local/share/sigrok/firmware per default:

$ cp sigrok-firmwares/asix-sigma/*.fw /usr/local/share/sigrok/firmware
