When developing ECG devices, engineers require fast and flexible testing to verify the effectiveness of design adjustments.

However, high-end simulators with comprehensive simulation capabilities require complex configurations, making repeated verification cumbersome after each adjustment. In contrast, relatively affordable entry-level simulators lack essential test signals, such as DC offset and noise simulation, making it harder for engineers to develop and verify their designs efficiently.

At the same time, EMC testing presents a great challenge in compliance testing. Current ECG simulators on the market cannot be tested alongside DUTs in EMC environments, forcing test engineers to develop custom workarounds—often leading to varying degrees of interference and suboptimal test results, resulting in costly and time-consuming retests.

To address these challenges, WhaleTeq developed the HECG100, offering an intuitive and efficient setup, advanced simulated signals essential for R&D testing, and EMC-ready specifications to streamline ECG device development and compliance testing.

R&D

The Challenges
• Rapid verification needed for design modifications
• Real ECG signal testing needed for performance evaluation
• Limited signal simulation capabilities in typical quick testers

What HECG100 Does
• Automated Test Sequences – users can define custom test sequences once and reuse them to verify design changes quickly, minimizing repetitive setups and human error*
• Raw Data Playback – utilizes clinical ECG signals to assess device performance in detecting and interpreting ECG waveforms
• Advanced ECG and Add-on Signals – provides a database of 32 arrhythmias, and a full suite of DC offset, noise, pacing, and respiration simulated signals for superimposing on configured ECG signals to closely resemble real-world scenarios

*Note: This feature will be available in a future firmware update. Release details and final specifications may vary.

Compliance

The Challenges
• Custom shielding workarounds are time-consuming and inconsistent, requiring a reliable simulator for EMC testing
• Preventing mains frequency noise interference from the simulator while ensuring uninterrupted testing for multiple evaluations in EMC environments

What HECG100 Does
• EMI- and EMS-compatible with ESD Protection – designed for use in EMC environments, ensuring stable and interference-free test signals without the need for additional mitigation strategies
• Rechargeable Battery – operates without external power sources, preventing mains frequency noise interference and enabling up to 12 hours of uninterrupted testing in power-saving mode
