Overview
- Single channel performance tester for diagnostic ECG, monitoring ECG and ambulatory ECG.
- Built-in test circuits per defined in ECG standards.
- Excellent shielding and grounding design makes amplitude and frequency accuracy < ± 1%.
- DC offset and pacemaker signal output can be adjustable.
- Load ECG file function enables to load and replay recorded or programmed waveforms.
- Offer alternative input of external generator for arbitrary waveforms.
- Software Development Kit (SDK) assists user to develop customized or automated test software with less efforts.
