After its introduction in 2008, StimTracker became key to integrating a psychophysiology lab, offering the first true plug-and-play solution for EEG recorders, eye trackers, NIR, and other recorders.
Feedback started pouring in. Some didn’t need all the features and wanted lower cost solutions. For them, we introduced last month our new c–pod and m–pod products. But other users needed even more features.
Today, I’m happy to announce StimTracker 2G, our next generation model, due out this coming October. The 2G model implements all the features requested by users – except one (but we’re working on it too).
StimTracker 2G comes in two models: Duo and Quad. StimTracker Duo offers dual outputs; StimTracker Quad gets you four outputs, with a possible fifth option (hint: a π); more on that below.
StimTracker (both old and new) accepts five sources of input: light sensors, audio, microphone voice key, key press information from an RB response pad, and USB event codes. The most vocal feedback about StimTracker 1G had to do with what input sources are being made available to the output, e.g. “why am I limited to 3 bits of USB event codes? I want all 8!”. Or, “I want to use all 4 light sensors”. So without further ado:
StimTracker 2G also includes all the new software features found in c–pod. There are other improvements as well, e.g. the ability to set the analog thresholds via software commands and the use of 4-layer circuit boards (instead of 2) to improve noise immunity.
What’s Gone or Replaced
The Duo model is housed in a thinner enclosure. Due to space and cost considerations, the voice key feature is now found in the Quad model only. For the same reasons, the Duo supports only two light sensors instead of four.
Also on the Quad model, the microphone and light sensor 4 share the same connector. You can use four light sensors and no voice key, or three light sensors with voice key.
And last, the big, bulky signal adapter blocks are gone and replaced by m–pod.
Summary of Differences
