TDualScan CR-M
I CR-M CR-M is a portable, mini-compact range suited to antenna measurement applications where space is limited or the flexibility of a portable system is required. The system is particularly well-suited for high frequency antenna and production testing.
I CR-M System overview VNA PIN Switch (optional) 959 Spectrum or MiDAS Workstation OFR 9800 Switch Controller (optional) PIN switch (optional) AL-4160 Series Positioner Controller The basic configuration allows for full 3-D patterns to be collected using standard Vector Network Analyzers. The chamber provides a modest level of shielding and easy access to the DUT positioner and compact range feed area.
