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.

== Protocol ==

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

== Firmware ==

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 [http://sigrok.org/gitweb/?p=sigrok-util.git;a=tree;f=firmware/sysclk-lwla 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).

Then:

<small>
 $ '''git clone git://sigrok.org/sigrok-util'''
 $ '''cd sigrok-util/firmware/sysclk-lwla'''
 $ '''./sigrok-fwextract-sysclk-lwla1016 LWLA1016'''
 [...]
 $ '''md5sum *.rbf'''
 9ea144768afdd3092712075c23eadca4  sysclk-lwla1016-100.rbf
 339d71ee799d3d3dbdcbcf1a00aa9f33  sysclk-lwla1016-100-ts.rbf
 77fe7158ee53dcbed3bf390ee753594f  sysclk-lwla1016-200.rbf
 e5246f3c1b9e3a34b570af9d50e02cbf  sysclk-lwla1016-200-ts.rbf
 d9f587c9f53d0706f25658bc5580e4f7  sysclk-lwla1016-250.rbf
 9d8c284bdbcfbad88aab9c2a79eb783d  sysclk-lwla1016-250-ts.rbf
</small>

Finally, copy all the extracted '''*.rbf''' files to the [[Firmware#Where_to_put_the_firmware_files|directory where libsigrok will look for them]].
