Switching Optical Routes Typical Applications
228 Agilent 8163A/B, 8164A/B & 8166A/B Mainframes, Sixth Edition
Selecting one of several DUTs in a parallel
test setup
In Figure 135 , two Agilent 81595B 1x4 Optical Switches are used to select
one of up to four DUTs in a parallel test setup.

Selecting one of several instruments
In Figure 136 , an Agilent 81595B 1x4 Optical Switch is used to select one
of up to four analysing instrument.

In each case, the advantages to be gained from using switch modules
include speedier changes to the test setup, and improved measurement
repeatability.
