USB Data Acquisition System (DAS)
USB Data Acquisition System (DAS)
The TREC-USB-DAS is basically a pure data acquisition & replay system for use with custom amplifier configurations, filter/amplifier systems or with programmable gain amplifiers also available from Thomas RECORDING.
Key features:- Easy setup
- Use it with any personal computer or notebook
- Portable system for use in more than one recording setup
Number of channels: | 16 (up to 32 optional) |

Coupling: | DC |
Data resolution: | 16bit |
Sample rate per channel: | 31kHZ |
Input voltage range: | ±10V |
PC interface: | USB 2.0 |
The TREC-USB-DASystem is a multichannel data acquisition for recording from up to 16 microelectrodes with additional digital and analog channels for external trigger signals. The system is delivered complete with analog to USB data interface hardware, software package and accessories.
If a TREC programmable gain main amplifier (PGMA-02) is used for neural signal amplification, the gain settings for each channel of the PGMA can be made via the graphical user interface of the TREC-USB-DASystem. The PGMA GUI of the TREC data acquisition system software is shown in figure 2.
For a fast overview of the selected gain settings of the programmable gain main amplifier (PGMA-2) each gain factor is color coded (e.g. x50=red, x5000=green, …) (see figure 2).
For display of the recorded signals we offer a single channel window with several display options as shown in figure 3.
Beside the single channel display we offer two different multichannel display windows. One window shows multiple recording channels in one window as multichannel oscilloscope mode (see figure 4).
Furthermore we have the option to display multiple recorded channels in a multiple channel window as shown in figure 5.
Multiple channel recordings are stored in data files on hard disc of the personal computer. You can open the files and display the recorded data with the replay function of the TREC-USB-DASystem (see figure 6).
The TREC-USB-DASystem consists of the following hard- and software components.
TREC-USB-DASystem data acquisition computer
- PC with monitor, keyboard, mouse
- With preinstalled hardware, operating system and data acquisition software
TREC-USB-DASystem main interface unit
- Data acquisition and analog-digital-converter board
- Interface for up to 32 inputs
- External power supply 100-240V AC
- Digital inputs/output
TREC-USB-DASystem software package
- Data acquisition software
For acoustic monitoring of recorded neural data we recommend our analog audio monitor. Digital audio monitors via PC sound card have delays which are not recommended for neural signal monitoring. Our analog audio monitor is connected directly to the main amplifier signal output and provides acoustic monitoring of neural signals without delays.
