•t Enhanced monitoring
•t 760 W of usable/available power
•t Optional backplane connector
shrouds and intermodule shield
•t Excellent cooling
Product Information
Chassis Extension
The 1261B-Linear mainframe was speci
fically designed for RF/Microwave and
Telecommunications applications, where
ultra-low power supply noise is critical. The
power supply is mounted in a separate
chassis for ease of maintenance, calibration, and rack installation. The two chassis
are connected via two cables designed for
fast installation and setup.
Cable Tray
Optional Enhanced Monitoring System
The 1261B-Linear’s microcontroller-based
Enhanced Monitoring System (EMS) provides a fully VXIbus compliant messagebased interface to the chassis. The EMS
reports to the user via the backplane using
individual commands or a soft front panel
interface. Additional features include front
panel alphanumeric display, individual VXIbus voltage status, and temperature rise for
each individual slot. It comes complete with
VXIplug&play drivers and soft front panel
interface.
Instrument Recessing
VXIplug&play-compliant instrument recessing provides room for connectors and cable
assemblies in front of each VXIbus module
without interfering with an interface panel.
Rack Mounting
The card cage of the 1261B-Linear has
optional rack ears allowing variable chassis
recessing up to 5 3/8” when mounted in an
equipment rack. This feature allows more
room for cables and large connectors.
Optional slides are available for the 1261BLinear card cage
ITA Receiver Extension (option 54-1) adds
additional space between modules and
ITA. This would be used in a rack with less
than 30-inch depth.
An optional 1 U size, 1.75-inch, cable tray
(option 721) allows cable access between
the front and rear of the chassis as well
as other instruments in the test system.
This allows rack-mounted instruments to
interface to the VXIbus resources or to an
interface test adapter mounted on the front
of the chassis.
Electromagnetic Compatibility
The 1261B-Linear has been tested for
EMC compliance to commercial (FCC
and CE) standards. Optional inter-module
shields (option 52) provide more shielding
between VXI modules.
Optional backplane connector shrouds (option 51) minimize radiated noise from the
module backplane.
Optimized Cooling
The 1261B-Linear mainframe takes advantage of an optimal “pressurized plenum”
design. Molded slot blockers prevent air
from diverting through unvented slots. This
approach directs unprecedented volume
of cooling air through your modules.
