We have been asked repeatedly by customers if FCC has formally approved the current cDASY6 implementation of MAIA ‒ SPEAG’s Modulation and Audio Interference Analyzer ‒ and how the results of MAIA should be reported. We are very pleased to announce that we have now received FCC's official confirmation on full acceptance of MAIA as well as further guidance on the reporting.
The development of MAIA was prompted more than five years ago by the concern of the regulators and test houses that, due the large variety of communication systems that need to be tested, the wrong UID, i.e., the wrong sensor model calibrated (SMC) probe linearization parameters, might be used by users of specific absorption rate (SAR) systems. As it is well known, SMC calibrated probes greatly improve the accuracy of SAR assessments and were therefore already approved by the FCC at the TCB Council Workshop in May 2017. SPEAG’s MAIA, in addition, increases the reliability of SAR measurements as it provides the necessary feedback to the user that the selected probe linearization parameters are valid for the signal being tested. This information is crucial as it confirms that the default uncertainty budget is not exceeded.
Watch the demonstration how MAIA is used to verify that the probe linearization parameters are valid for the uplink signal being measured.
During the last few weeks, SPEAG has clarified with the FCC how the linearization parameters verification with MAIA should be documented in the SAR reports. It was agreed to use the following four status characters:
“Y”: Linearization not required / Linearization parameters confirmed by MAIA
“N/A”: MAIA not used
“N”: Linearization parameters not valid
“E”: MAIA error
The latest cDASY6 SAR Module release (V6.8.2) features the new reporting format of MAIA results as agreed with the FCC. The software installer as well as the complete list of the minor but important improvements are available on the DASY6 website.

We have released iSAR² software version 2.2. New features include remote control of the iSAR² using customer-specific programs, enhanced graphical information of the iSAR² operation, and full compatibility with Windows 7 and Windows XP in 32-bit and 64-bit versions.
SPEAG started to integrate 3rd-Party Probes for our DASY52 NEO systems. The first probes are the 3-axis hall field probe series from MetroLab that enpower DASY52NEO to scan DC/ELF magnetic fields with high precision.
The new MEM Phantom was desgined and optimized for compliance testing of wireless devices and other electromagnetic emmitting devices that may be partially surrounded by tissue or in direct contact with the skin, e.g., wireless hands-free kits, hearing aids, skin mounted devices, inductive activators, etc.
SPEAG introduces a new series of tissue simulating liquids that are broad-band based on the environmental friendlier Tween ingredient and fully compliant with the new IEC/IEEE standards allowing ±10% tolerance on the liquid parameters.
The National Research Council Institute for Biodiagnostics (NRC-IBD) has teamed up with SPEAG to offer a unique software platform for magnetic resonance imaging (MRI) scanner design. The new platform seamlessly integrates powerful new tools for radiofrequency (RF) array design and post-processing and is the first software of its kind to combine all the tools needed to design RF-phased arrays into a single user friendly program.
This new product PRE - 10 is a 3 channel voltage divider which extends the operation of existing SPEAG probes for use in very high fields (> 5 kV/m; > 10 kW/kg). It is compatible with all our E-Field, H-field and SAR probes.
