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.

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. The chamber is mounted on a caster assembly for
convenient transportation between different production or
test sites.
A compact range feed polarization rotator enables the
transmit polarization to be changed during a single test or
in between tests. Linked axis motion of the transmit rotator
and roll axis allows for automatic acquisition of E & H plane
patterns in a single test. A squint (elevation) axis allows
E&H plane patterns through the peak of the beam in case
electrical and mechanical boresight do not coincide. The
AL-4160 series controller supports the control of up to four
(4) axes, and allows for simultaneous motion if required.
Optional pre-test or real time switching through the usage
of the OFR 9800 high speed switch controller, that enables
the collection of multiple channel data.
The data acquisition workstation comes equipped with
either the 959 Spectrum or MiDAS software, depending
on location, allowing for a versatile and powerful data
acquisition and analysis tool. Upon request, the compact
range reflector and positioner system without the installation of a portable anechoic chamber can be procurred by
customers with existing anechoic chambers.
