Software
DLL Driver:
The UBA-4204 comes with a fully-documented DLL interface allowing you complete control through your own software written in LabVIEW, MATLAB, Visual C++, Borland C/C++, or Visual Basic. The DLL driver allows control over:
- Sampling frequency
- Number of samples
- Continuous data collection (streaming)
- Channel selection
- Amplifier gain
- Impedance test
- High pass and low pass filter corner frequencies (arbitrary frequency)
- Notch or comb filter frequency (arbitrary frequency)
- Reporting of battery charge state
- Power off amplifier
Demonstration Software:
The UBA-4204 also ships with a ready-to-run demonstration program that allows collection and display of data. Many
key parameters of the UBA-4204 can be controlled from this package.
