SAGA 32+/64+ is a 32 or 64 channel amplifier for electrophysiological measurements such as EEG or HD EMG. The SAGA consists of two separable parts, a Data Recorder and Docking Station.
The Data Recorder contains the amplifier that measures the electrophysiological signals from your brain, muscles, heart or any other bio-electrical source. The Data Recorder can connect to the SAGA Docking Station in three ways: docked to each other, via Wi-Fi or via optical fiber. Use the Data Recorder without the Docking Station in ambulatory mode for home monitoring or outdoor use.
The Docking Station is the communication interface to your PC and the main processing unit of data packages. It collects the data from the Data Recorder, together with any additional event triggers on the 16-bit trigger input and keeps track of any lost data in wireless transmission. The data is send to the PC via the USB output or Ethernet output.
Reliability of a stationary setup
The Data recorder, docked on the docking station gives you the highest sampling rate, reliable, most real-time data transfer and a clean desk setup. Use the 16-bit trigger input for your event logging.
Up to 16 supplementary inputs to complete your setup
With two dual bipolar inputs and three triple auxiliary inputs and a digital input, the plus in SAGA 32/64+ is a real plus. Add EOG, ECG, or sensors such as skin conductance, 3D accelerometers to the setup, to get an even more complete dataset.
Dual bipolar means that you can connect up to 4 bipolar channels. Triple auxiliary means that there are three channels in one input: you can connect up to 9 sensors at te same time!
The digital input can be used for a digital sensor, such as a NONIN saturation module.
Freedom of movement in portable setups
By separating the Data recorder from Docking station, you have optimal freedom, without changing the interface on the PC side. The Docking Station acts as receiver station for the wireless data transmitted by the Data recorder. Any lost data is marked here and can be downloaded from card after the measurement.
Ambulatory use for data logging and outdoor use
The data logging without data transfer is ideal for ambulatory measurements or outdoor use. During setup you monitor the electrode impedances and data quality. You start the recording and can be sure your data is stored on the onboard memory and downloaded after the experiment. Clean and easy.
Certified Medical Device Class II (Pending)
You need to be sure our products are safe to use for your research. Regardless if you use the device on healthy ‘subjects’ or patient groups, our device is fully certified and tested on the latest regulations and standards. In many cases, ethical commitees are easier to convince if you use a medically certified device.
It is a black box, but not a black box.
Our systems are not a black box. We are open and transparent about our technology. The data is clean, but not manipulated. We do not include filters in our hardware, to give you true and honest data. It is all about well-designed technology and transparency. Interested?
We believe in quality
Garbage in, is garbage out. If your measurement setup or protocol is not well designed, your results will not be good. The same is true for the devices you use. If your device cannot handle harse environments, your data will not be good. Nothing worse than a measurement full of mains interference and artefacts. Correcting for artefacts takes a lot of time and also changes your real signals. We designed our systems such that we keep your signals clean. Read more about how we keep mains interference and cable movement artefacts out of our signals in our blog about measurement technology.

TMSi Polybench is a software application toolbox, a veritable blank canvas for the creation of customized configurations; from basic measurements to sophisticated research applications. The possibilities are limited only by your imagination.
TMSi Polybench can be considered a personalized “application factory” allowing the user to control the high-quality raw data input from any TMSi amplifier to build the exact system they need. Choose among TMSi Polybench pre-set functions and controls or build customized processes in pursuit of practically any conceivable desired outcome.
In research, by definition, the questions being asked have specific challenges that off-the-shelf software often cannot be adapted to meet. TMSi Polybench allows you complete freedom in design so that data collection, measurement and manipulation is completely under your direction and not limited by the design of any specific software offering or system manufacturer.
TMSi Polybench can accept input from all TMSi amplifiers.
The TMSi MATLAB Interface is a library for MATLAB written by TMSi to interface the TMSi PC Driver to MATLAB. This interface allow you to acquire data, write and read. poly5 files via MATLAB and/or export data to EEGLAB (http://sccn.ucsd.edu/eeglab/).
Functionality that is included in the TMSi MATLAB Interface is limited to the signal acquisition part of the driver and loading data from previously recorded data in TMSi Polybench or the TMSi MATLAB Interface. All functionality needed to perform on-board memory recordings (so-called ambulatory measurement) as present in the Mobita, Mobi and Porti is NOT implemented.
The code in the TMSi MATLAB Interface is a MATLAB library for sampling TMSi devices. The goal of this library is to give an easy programmable interface to TMSi devices. It contains basic examples that should be enough to get you started.
The library provides: • Sampling from USB, Wi-Fi, network and Bluetooth TMSi devices. • (Limited) Real-Time plotting of sampled data. • Directly saving sampled data to .Poly5 file format. • Offline export of .Poly5 data to EEGLAB. • Support for sampling using SynFi and Fusbi.
Note that TMSi does not support usage of the TMSi Interface for MATLAB.
The interface is distributed under MIT license, but can not be supported by TMSi support personnel.
Compatible with the following devices: REFA Extended, REFA, Mobita, Mobi, Porti.
