cSAR3D Software (Version 5.0)

Algorithms

Precise and fast SAR measurements are made possible using:

• Advanced algorithms for accurate reconstruction of the complete 3D SAR distribution
• Fast spatial averaging and display of peak 1 g and 10 g SAR
• On-the-fly uncertainty calculation for each measurement, based on the field distribution and other SAR measurement parameters
• X10 Combiner for high-resolution measurements on cSAR3D Flat

Speed

A complete SAR assessment is now 0.3 seconds. The software can acquire SAR measurements, reconstruct the induced fields in 3D, time-average and determine the peak spatial SAR values averaged over both 1 gram and 10 grams three times per second – by far the fastest SAR measurement system on the market.

This enables high sample rate testing of SAR management features such as dynamic power control, antenna switched diversity, and proximity sensing.

Test Plan Implementation

A versatile interface allows for the set up and automatic execution of a test plan:

• Set up a test plan manually or using the Python interface
• Display all test configurations of a wireless device in a single visual
• Easily add or remove measurements, and change the measurement order
• Select any or all configurations for automated measurement

Visualization

Visualize the data and test configuration:

• Display all measurement results of a wireless device in a single visual
• Visualize the SAR pattern in slices or grid
• Include photo of DUT overlayed on SAR distribution
• Zoom in on specific measurements to view more detail
• Color-coded information shows the highest SAR test conditions at a glance

Base Station Simulator Integration

For fast and automated control of cSAR3D measurements, the following base station simulators have been integrated:

• Rohde & Schwarz CMW500
• Rohde & Schwarz CMU200
• Keysight E5515C/E 8960
• Anritsu MT8820C
• Anritsu MT8821C
• Anritsu MT8000A (coming soon)

Python interface enables the user to program and control base station simulators and other hardware.

Expert System

An expert system is integrated into the cSAR3D software:

• Automated guidance through the standardized testing process
• Apply rules to highlight additional testing or apply test reductions
• Import or export measurements between cSAR3D and DASY6/DASY8

Report Generator

With the click of a button, SAR measurements can be saved in different formats to create SAR test reports:

• Generate 3D views of measurement data for use in SAR test reports
• Export tabular data of peak spatial-average SAR to Excel or Word

Automated Control

The built-in Python scripting interface and Remote Client give you high-level control to:

• Create custom test configurations
• Control equipment via GPIB (e.g., base station emulators)
• Conduct statistical postprocessing of the measurement data

Test scripts and customer support are provided by SPEAG. 

Device Positioning

Additional DASY8^3D software module controls robot movements to pick up and position a wireless device on any cSAR3D phantom. Thousands of SAR measurements can be performed with just one click.
