Tracing EM Interference
The QUANTIEN™ measurement system uses digital signal processing techniques that operate in
the radio frequency (RF) energy range.
The system is therefore susceptible to interference generated by other RF energy sources such as
medical devices, information technology products, or radio/television transmission towers.
Tracing the source of radiated interference can be difficult. In accordance with the standards
identified in these Instructions for Use, no interference was observed. However, the trained user
must determine if an artifact caused by radiated interference will negatively impact signal quality
and the subsequent study results.
To help identify the source of electromagnetic interference, ask the following questions:
Is the interference intermittent or constant?
