Agilent 83491/2/3A Modules—At a Glance
The Agilent 83491/2/3A are designed to operate in an Agilent 83480A digital
communications analyzer. These modules recover clock and data information
at standard telecom and datacom rates. The resulting trigger signal is made
available to the Agilent 83480A mainframe via a connector located on the
module’s rear-panel. An external front-panel cable passes the data signal, with
some insertion loss, to the receiver module.
