4. LOW FREQUENCY RESPONSE AND
STANDING-WAVE-RATIO (SWR) DATA
The typical performance data that follows is not guaranteed, however, it represents a large number of
production units processed.
Therefore, it is a good guideline for user expectations.
The worst case
specifications are quite conservative in accordance with AR general policy.
Detailed SWR data is supplied with each head unit shipped against a customer order to give the user specific
information required to properly evaluate errors in a particular application. Please consult the factory for
optional units with more stringent specifications.
The typical low frequency response for three head models are shown in Figures 4-1 through 4-3. Figures 4-4
through 4-10 represent SWR Data.
