Theory of operation
82A04B phase reference module
The 82A04B Phase Reference Module is designed to decrease horizontal position
uncertainty with data signals, when a reference clock signal synchronized to the
data signal, is available. It consumes a small slot, and displaces operation of
both channels in that slot.
The available Phase Correction modes are free run (where the module provides
unit circle location information for the phase of the data sample) and triggered
(where the module, with the trigger signal, provides both base positioning, and
re
fi
ned positioning, for the data sample).
The input connector is a precision 1.85 mm connector. Phase correction
works over the range of 2.5 GHz - 25 GHz (82A04B), or 2.5 GHz - 60 GHz
(82A04B-60G).
The LED on the module indicates that the module is being used for phase
correction.
