Agilent Technologies 86060C Product Overview page 5

If more than fifty channels are
required, another blocking
solution is available in the "C"
version by adding an Mx1
switching element in front of a
1xN armature switch (See
Figure 8). The implication of
this design is that there is
slightly higher insertion loss
than the standard "C" specifi-
cation, and the input/output
channels are controlled on
two separate layers via front
panel keys or remote control.
When programming the switch,
two SCPI commands are need-
ed to connect a one of the
input channels to a desired
output channel.
More Than
Two Input Channels
The 8606xC family of switches
can be configured to have
more than 2 input channels.
Up to 4 input channels can be
accomodated. Figure 9 depicts
a 4xN configuration. In this
design, the four input arms
move together to connect any
input channel to any output
channel.
For other types of special
configurations (such as angled
connector contacts, enhanced
specifications, special fiber
type, etc.), please contact your
local Agilent field representative
or regional customer call center.
