Software downloads & release notes

Electron Plus software is built to work exclusively with our hardware; it is free to download and use with our products. As with most software, there will be continuous updates (as well as bugs/anomalies). Any and all feedback is welcome, and we will do our utmost to fix problems in a timely manner.

Most of our instruments use FTDI USB chipsets, you will need to download and install the D2XX driver from FTDI on your computer; we suggest that you do this BEFORE plugging in your instrument, we have included a link to this driver below. SPA100 and CTL502 products both use CH340C USB bridge IC’s. Driver is included within.
