T- DualScan FScan
FScan is a vertical near-field planar scanner system that is a perfect solution for antenna measurement applications where a phased array, high gain, or reflector antenna is under evaluation. The FScan system is suitable for small to medium antennas due to the slim cross section scanner structure that fits into small chambers and allows maximum travel. + Slim cross- section structure SOLUTION FOR Phased Array Antenna Testing High Gain Antenna Testing Near-field Focused Antenna Testing Array Illumination Assessment Array Element Failure Analysis Main features Technology Near-field/Planar Optional: - Near-field/Spherical - Near-field/Cylindrical Measurement capabilities Gain Radiation pattern Beamwidth Cross polarization Sidelobe levels Element performance Array illumination Frequency bands 100 MHz to 110 GHz Scan sizes Standard systems ranging from 4 x 4 to 13 x 13 ft (1.2 x 1.2 to 4 x 4 m) Other sizes available upon request Positioning equipment Frame scanner with Z-roll probe mount System configurations Software Measurement control, data acquisition and post processing 959 Spectrum (North America only) with NF/FF planar transform* MiDAS with NF/FF planar transform Equipment Planar box scanner Z-roll probe mount AL-4164 positioner controller* Scanner absorber treatment*** Rotary joint for roll axis* RF cables* Uninterruptible power supply Vector network analyzer DUT stand Add-ons RF system upconverters/downconverters above 40 GHz DUT positioner axes for upgrade to cylindrical or spherical NF* Cylindrical and spherical software transform* Portable absorber walls*** StarLine linear probe array Shielded anechoic chamber*** Accessories Data acquisition workstation Near-field open-ended waveguides** Standard gain horns** High speed channel switching (OFR9800)* Near-field broadband dual polarized probes with interchangeable aperture** Services Installation Warranty Training Post-warranty service plans**** MV-Cor correction table service****** Included Optional Required * See the ORBIT/FR product catalogs for more information ** See the MVG antenna catalog for more information *** See MVG-EMC Systems catalogs for more information **** See Orbit/FR service brochure for more information ***** See MV-Cor TM brochure for more information 107 2
System overview PIN Switch (optional) VNA Data Acquisition Workstation OFR 9800 Switch Controller (optional) PIN Switch (optional) AL-4164 Series Positioner Controller The standard system is able to collect high resolution antenna planar near-field data using standard Vector Network Analyzers. The AL-4164 controller allows the simultaneous control of up to four (4) axes. Additional units can be added when upgrading to cylindrical and/or spherical. The data acquisition workstation is equipped with either the 959 Spectrum or MiDAS software, for powerful data acquisition and analysis. The optional MV-Cor TM correction table service allows physical errors to be measured using a laser tracker system or other optical device. The data is entered into the positioner controller. Real-time corrections to the errors of up to 3 axes (X, Y and Z) are applied to the demanded positions for data acquisition. Optional pre-test or real time switching via the OFR 9800 high speed switch controller enables the collection of multiple channel data. PIN switches can be added for dual probe as well as multiple channel DUT applications. An optional modular shielded anechoic chamber with absorbers sized to the appropriate frequency range and/or portable absorber walls are available for temporary or cost effective measurement set-up. 108 3
