DE04-2 Multi-Axis Automated Reference Frame
Basic Usage
The DE04-2 Reference frame system is designed for mounting a reference antenna, a device under test (DUT) or materials under test (MUT). The frame can be moved on the Z-Axis (horizontal in reference to positioner) or rotated on the azimuth axis a full 360 degrees.
Mirror Method Usage
When the 4-foot reference mirror option is installed, single antenna real-time vector S-Parameter gain measurements may be performed using Diamond Engineering’s proprietary software algorithm. This methodology has been shown to be more accurate and much faster than the traditional 3-point method. This method involves simple S11 measurements. Expensive VNAs are not required for this method of antenna calibration (only a low-cost single-port VNA is necessary). 1-meter and 3-meter measurements (or anything between) become trivial.
The mirror plane is made parallel using a laser and an optically flat mirror. Can also accommodate material for measurement from 1 to 4 sq. ft using Diamond Engineering’s Material Measurement Software (as shown below).
