The Sysclk LWLA1016 is a USB-based, 16-channel logic analyzer with up to 100MHz sampling rate, or up to 250MHz with 8 channels.

Note that sigrok supports only the 100 MHz mode with 16 channels. Supporting the 200/250 MHz 8 channel modes is not worth the effort, since the device does not support triggers in these modes. A non-streaming device without triggers is pretty much useless for any real world application.

See Sysclk LWLA1016/Info for more details (such as lsusb -v output) about the device.





Reverse engineering of the vendor's custom protocol is complete. See Sysclk LWLA1016/Protocol for the findings gathered.


In order to use this device you'll have to place the correct firmware files into a directory where libsigrok is looking for them. See Firmware#Where_to_put_the_firmware_files for the OS-specific details.

For the LWLA1016 we provide a script, which can extract them from the vendor software.

First you'll need to install the (Windows) vendor software and grab a copy of its installation directory, e.g. C:\Program Files\LWLA1016 (or similar, depends on where you installed).


$ git clone git://
$ cd sigrok-util/firmware/sysclk-lwla
$ ./sigrok-fwextract-sysclk-lwla1016 LWLA1016
$ md5sum *.rbf
9ea144768afdd3092712075c23eadca4  sysclk-lwla1016-100.rbf
339d71ee799d3d3dbdcbcf1a00aa9f33  sysclk-lwla1016-100-ts.rbf

9d8c284bdbcfbad88aab9c2a79eb783d  sysclk-lwla1016-250-ts.rbf

Finally, copy all the extracted *.rbf files to the directory where libsigrok will look for them.
