ASIX SIGMA / SIGMA2
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 per default:
$ cp sigrok-firmwares/asix-sigma/*.fw /usr/local/share/sigrok
