T- DualScan
FScan
I 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.

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.
TM
The optional MV-Cor
correction table service allows
physical errors to be measured using a laser tracker system
PIN Switch (optional)
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.
