MI-6480 Family of Field Probes
 Features:
- Designed to evaluate the quality of your antenna or RCS test
zone
- Excellent Linearity for accurate phase measurements
- Fast, Accurate Range Evaluations
Description
In making precision antenna measurements, it is desirable to
determine the nature of the incident field over the test
aperture. This is necessary to evaluate field variations caused
by extraneous signals arriving at the test aperture. The MI-6481
Phase/Amplitude Field Probes are designed to mount to a
positioner for use in evaluating the field. These
Phase/Amplitude Probes offer excellent linearity to evaluate the
quality of the incident phase for even the most demanding
applications.
Each model in the family includes:
- Phase/Amplitude Field Probe with a rack and pinion linear axis
- Standard roll axis
- Absorber to cover the probe (combination of 3 and 6 inch)
- RF cable included (18 GHz, precision-N connectors)
- Probe to Positioner interface
The MI Technologies MI-6481 Phase/Amplitude Field Probes can be mounted on MI
Technologies as well as many third party positioners. Some mounting applications
may require additional adapters.
