Features	EASY4MRI is compatible with DAEasy4MRI that have been extra hardened for operation with electromagnetic hostile environments from static to RF. The software has been optimized for MRI applications.
Field Measurement Capability	E-field	frequency range: 20 - 6000 MHz dynamic range: 2 - 1000 V/m spatial resolution: < 7 mm directivity: < ±0.3 dB
	H-field	frequency range: 20 - 3000 MHz dynamic range: 10 - 2000 mA/m at 1 GHz spatial resolution: < 4 mm directivity: < ±0.2 dB
	SAR	frequency range: 10 - 6000 MHz dynamic range: 5uW/g - 1000 mW/g spatial resolution: 2.5 - 7 mm directivity: < ±0.3 dB
	T	dynamic range: 0°C - 60°C noise: < 2 mK (sampling time: 0.1s) spatial resolution: 1 mm
Sampling Rate	< ms - hours
Applications	Incident fields dosimetry and temperature evaluation in MRI or other EMF hostile environments Short and long-time high precision field monitoring
Phantom	ASTM Phantom for testing compliance of implants within MRI Environments
Working Modes	Field strength meter (display of values, min, max and statistics) Scope meter (field components or total values vs. time) Separate process with individual parameters for each channel Remote operation capability
Minimum Requirements	One DAE4MRI and one field or temperature probe (not included)
