DASY6 Module mmWave V2.2: Fully Compatible with IEC/IEEE 63195-1/-2 FDIS

SPEAG has released DASY6 Module mmWave V2.2 together with the MEO and API Options. Version 2.2 fulfills all requirements of the Final Draft of the IEC/IEEE 63195-1/-2 and national regulations (e.g., in the United States, Canada, and Japan) and offers the necessary features for MIMO testing and for testing automation above 6 GHz

Even before the Final Drafts (FDIS) of IEC/IEEE 63195-1 and 63195-2 have been submitted to the national committees for voting, SPEAG has released DASY6 Module mmWave V2.2. Version 2.2 is fully compatible with these standards, giving all DASY users a head start in compliance testing. The new key features are:

  • Updated computation of the spatial-average power density (sPD) 
  • Measurement automation with the API (Application Programming Interface) Option
  • Release of the MEO (Maximum Exposure Optimizer) Option for evaluation of MIMO antennas based on measurements only
  • Auto-Extend feature to automatically increase the measurement grid when the user-specified one is not sufficient for PD evaluation

Updated Spatial-Average PD (sPD) Algorithm

Sim4Life/SEMCAD X and DASY6/8 have reached another level of integration and sophistication. DASY6 Module mmWave V2.2 and Sim4Life V6.0 use identical software modules to interpolate and compute the various sPD values as defined in IEC/IEEE 63195-1/-2 or by national regulators on any surface. The implemented algorithms are currently the fastest for determining the following:

  • sPDn+: surface normal propagating power flux density into the phantom (square and circular on planar surfaces and spherical on any other surface)
  • sPDtot+: total propagating power flux density into the phantom (square and circular on planar surfaces and spherical on any other surface)
  • sPDmod+: total power flux density into the phantom considering near-field exposure (square and circular on planar surfaces and spherical on any other surface)

Note that with the next release, an optimized algorithm to compute sPD using a rotating cube on non-planar surfaces will also become available.

11470243sPDn+ measured at 2 mm distance from the surface of the CDA-10G (Cavity Dipole Array 10 GHz).

Beam-Forming / MIMO Transmitter Evaluation with the MEO Option

Beam-forming technologies are commonly used in mobile devices supporting 5G New Radio Frequency Range 2 (NR FR2), also often referenced as MIMO antennas. The direction of the beam is controlled by changing the relative phase and amplitude of the signal at each transmitting element of the antenna array. However, the codebook, which represents all possible steering directions, can be too large, meaning that it is not realistic to measure each configuration individually.

Our advanced MEO Option for fast and reliable determination of the maximum exposure for any small to very large MIMO transmitters for Sim4Life/SEMCAD X is now also available for DASY6 Module mmWave 2.2+. Combined with the FTE (Forward Transform Evaluation) Option, it is the most effective way to determine the maximum peak spatial-average mpsPD within any volume or on any surface for an infinite or user-specified codebook.

Automatic Extension of the Measurement Grid

In DASY6 Module mmWave V2.2, the measurement grid will be automatically extended during scanning in case the initial user-specified grid size is not sufficient to ensure accurate PD evaluations. The measurement grid will be auto-extended if:

  • the peak spatial-averaged PD (psPD) is on the boundary of the sPD grid (5G / FT scans)
  • expanding the measurement region changes the psPD values (5G / FT scans)
  • the radiated energy on the measurement plane has not been fully captured (FT scans)

This new feature eliminates the need to repeat scans and leads to further time saving during PD compliance testing.

Measurement Automation with the API Option

After the successful launch of the API Option for DASY6 Module SAR in May 2020, the API Option is now also available for Module mmWave. Together with the automatic extension of the measurement grid and the new DAE4 with Integrated Power (DAE4ip), the measurement process can be fully automated:

  • User-specific tools (e.g., test software) can be integrated to set the device under test to the desired transmission mode without interrupting the measurement sequence
  • Dynamic decisions about the next scan can be taken to allow automation of customized test-reduction procedures

Based on a web framework, the API Option is compatible with a broad range of programming languages and operating systems.

The Jupyter Notebooks available in the DASY6 Module SAR API Tutorial have been improved to guide users in the development of customized scripts via interactive examples.

Existing user programs for Module SAR can easily be ported to Module mmWave as the set of commands are very similar.

User-Friendly Robot Commands

The user-friendly robot commands introduced in Module SAR V6.12 have been ported to Module mmWave V2.2:

    • Move to the phantom “Section Home” Point
    • Move to the phantom “Section Park” Point
    • Move to a user-defined point (i.e., Global Park)

All features have been extensively validated and results can be exchanged between the DASY6 and Sim4Life/SEMCAD X, providing significant advantages for R&D teams using both measurements and simulations side by side. With next release, DASY6/8 Module mmWave 3.0, scheduled for 2Q2021, users will be able to directly use measurement results to perform simulations, eliminating the need to import and validate transmitter modules.

The new DASY6 Module mmWave V2.2 software can be downloaded here.
