ASIX SIGMA.
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. In other modes, users can specify additional trigger values, listed in the table below.

Samplerate Number of probes Trigger support
200 kHz 16 Edge of two probes, state, boolean expression1
250 kHz 16 Edge of two probes, state, boolean expression1
500 kHz 16 Edge of two probes, state, boolean expression1
1 MHz 16 Edge of two probes, state, boolean expression1
5 MHz 16 Edge of two probes, state, boolean expression1
10 MHz 16 Edge of two probes, state, boolean expression1
25 MHz 16 Edge of two probes, state, boolean expression1
50 MHz 16 Edge of two probes, state, boolean expression1
100 MHz 8 Edge of one probe
200 MHz 4 Edge of one probe

1 Boolean expression feature not implemented in sigrok yet.

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

Example usage

An example that captures from 4 probes, for 100ms at 10 MHz, with trigger condition 1:high, 2:rising, 3:low, 4:high. 

sigrok-cli --wait-trigger --triggers 1=1,2=r,3=0,4=1 --samples 5000000 --time 100 -o samplerate=10m -f bits -p 1-4

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
