Specifications
Description
The Agilent E8401A C-size, 13-slot VXI mainframe is the
lowest-cost mainframe in Agilent Technologies’ VXI
mainframe family. It delivers innovative cooling technology,
improved backplane design, high reliability, easy
maintenance, and versatile accessories. The power supply in
the E8401A VXI mainframe provides 500 watts of usable
power, sufficient for most automated test applications. The
innovative air distribution system provides extremely quiet
and efficient cooling. Basic mainframe monitoring of the
E8401A indicates normal operating conditions at a glance. A
front panel diagnostics connector allows continuous local or
remote system monitoring. This mainframe also complies
with the VXI Specification by providing injector surface rails
used by the QUIC easy module insertion and extraction
system. Superior cooling, reliable design and system
monitoring make the E8401A an excellent choice for most VXI
test system applications.

recent product updates, if applicable.
500W Power Supply
The E8401A VXI mainframe features over 500 watts of usable
power from 0 °C to 55 °C. Ample dynamic and peak currents
are provided for most applications.
Superior Cooling
The innovative cooling design in the E8401A VXI mainframe
provides extremely quiet and efficient cooling. Carefully
engineered airflow provides the ultimate in cooling with a
minimum of noise. Outstanding back pressure performance
insures airflow through dense modules. Separate power
supply cooling fan(s) provides an independent air path for
reliable cooling of the power supply.
All fans operate in either Variable or Full Speed mode. A two-
position switch on the mainframe’s front panel controls the
speed mode. Full Speed mode is recommended for maximum
cooling and/or if acoustic noise is not a concern; all air
movers (cardcage impeller and power supply fan(s)) are
operated at full capacity at all times. In Variable Speed mode,
the fan speed will vary depending on the temperature rise in
the mainframe, and the ambient temperature. Variable Speed
mode operation allows the quietest operation while providing
sufficient cooling for the modules in the mainframe.
Airflow is conveniently routed into the rear and exhausted
out the sides of the mainframe. This allows mainframes to be
stacked or rack-mounted directly on top of one another.
