The Sysclk SLA5032 is a USB-based, 32-channel logic analyzer with up to 500MHz sampling rate.

See Sysclk SLA5032/Info for more details (such as lsusb -v output) about the device.

This devices can be switched into one of three different modes (the current mode is indicated by a green LED on the respective mode text):

  • 32CH 500M: 500MHz sampling rate, 32 channels, max. 64Mbits storage per channel, support for hardware triggers (sysclk-sla5032 driver).
  • Saleae 100M: The device enumerates as a Saleae Logic16, streaming possible like with the Logic16, only software triggers (saleae-logic16 driver).
  • Saleae 500M: Similar to the above, but the max. sampling rate is actually 500MHz.

Switching between modes is done via the following mechanism: Plug the device into USB, after roughly half a second unplug it and re-plug it again. A green LED will now indicate that another mode was selected (it'll rotate through all three possible modes).

In order to use this device, you need a firmware/bitstream file from the vendor software (from the CD-ROM shipped with the device or from a vendor download of the software). You can e.g. install the Windows vendor software, then get the file C:\Program Files (x86)\SLA5032\bin\top.bit, rename it to sysclk-sla5032.bit and place it in a location where libsigrok will search for firmware (see libsigrok's README.devices file for details).
