MilliBox demonstrates the capabilities of its brand new GIM05 mmWave and THz mmWave spherical roll and polarization controller positioner in its MBX02 benchtop 4 ft anechoic chamber using Anritsu’s ShockLine™ ME7868A distributed modular two-port vector network analyzer (VNA). This distributed VNA is interesting when the two ports to be measured are distant, which is the case when doing over-the-air antenna measurements in a chamber like MilliBox’s.
Jeanmarc Laurent, creator of MilliBox stated,” The distributed ShockLine VNA like the ME7868A is very practical for over-the-air measurement done in MilliBox setups because they are modular in size to accommodate far field distance up to 3 m and traditional built two-port VNA are difficult to wire at those distance. RF coax of this length and at those frequencies are a big challenge, but thank to this distributed configuration the problem is eliminated.”
Navneet Kataria, Product Marketing Manager for Anritsu benchtop VNA product line, stated that the “revolutionary ME7868A has 2x single port VNA that are connected by Anritsu patented technology called PhaseLink™ which allows the two ports to make vector corrected S parameter measurements over distances greater than 100 meters.” This distributed configuration is controlled from a remote PC which also host the MilliBox Positioner controller such that all the controls for this measurement are at user’s fingertip under one screen.
