SPR-SCANNER
The SPR-Scanner is a planar near field scanning system developed by Sunvey Technologies. It has ultra-high precision electrical motion control
system and mechanical drive system. Once adapted with probes of different frequency, ultra-wideband measurement can be achieved, and can even be extended up to millimeter wave.
