Reliability of a stationary setup

The Data recorder, docked on the docking station gives you the highest sampling rate and most real-time data transfer.


Freedom of movement in portable setups

By separating the Data recorder from Docking station, you have optimal freedom. 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 after the measurement.


Outdoor use

SAGA allows data logging oin its on-board memory and is ideal for ambulatory measurements. 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.

Bipolar and Auxiliary inputs

Up to 16 additional 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 or 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 the same time!

The digital input can be used for a digital sensor, such as a NONIN saturation module.


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 harsh environments, your data will not be good. Nothing worse than a measurement full of mains interference and artifacts. Correcting for artifacts takes a lot of time and also changes your real signals. We designed our systems in such a way that we keep your signals clean. Read more about how we keep mains interference and cable movement artifacts out of our signals in our blog about measurement technology.

Technical Concept

Separable Docking Station and
Data Recorder

We support the various use scenarios with the innovative Data Recorder – Docking Station concept. This gives the optimal data transmission in stationary/lab setups and the optimal wearability in mobile or outdoor setups.

More on the concept

Data Recorder

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.


Docking Station

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.


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?

Open Data Access

It is a black box,
but it is not a black box.



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.

MATLAB Interface

SAGA Interface for MATLAB

The SAGA Interface for MATLAB is a library for MATLAB that allows direct interfacing to TMSi amplifiers to acquire data, write and read (.poly5) files via MATLAB and/or export data to EEGLAB (

The goal of the library is to give an easy programmable interface to SAGA 32+ and SAGA64+. It contains basic examples that should be enough to get you started.

The library provides:
• Sampling from SAGA 32+ and SAGA 64+.
• (Limited) Real-Time plotting of sampled data.
• Directly saving sampled data to .Poly5 file format.
• Offline export of .Poly5 data to EEGLAB.

The SAGA Interface for MATLAB is a free library available for download. TMSi supports the usage of the interface to the extend of the installation of the interface, communication between driver and interface and the interface itself. Note that TMSi cannot support the usage of MATLAB.

The interface is distributed under MIT license. Please respect the license conditions. Note that functionality for on-board (ambulatory) recordings on SAGA is not supported by the SAGA Interface for MATLAB. This requires a TMSi Polybench license.

The SAGA Interface for MATLAB can be found here.

The SDK can be used by software developers to interface to SAGA32/64+. Please contact us for more information.
