Agilent HP E8403A C-size VXI mainframes

The Agilent Technologies E8400 Series of 13-slot, C-size VXI mainframes provides a wide range of mainframe solutions
to meet all your test system needs. They deliver innovative cooling technology, improved backplane design, high
reliability, easy maintenance, and versatile accessories. The innovative air distribution system used in all three
mainframes provides extremely quiet and efficient cooling.

The power supply in the E8401A VXI mainframe provides 500 watts of usable power, sufficient for most automated test applications. The power supply in the E8403A and
E8404A VXI mainframes provides 1000 watts of usable power, sufficient for the most demanding automated test applications. Ample dynamic and peak current capability
is provided for most applications.
The basic mainframe monitoring of the E8401A and E8403A indicates normal operating conditions at a glance.
The enhanced monitoring of the E8404A mainframe provides superior cooling control and details regarding
temperatures throughout the mainframe, power supply voltages and currents, fans operation, system status,
history queue, and stripcharts or histograms for easy diagnostics. This information is available on the full color
display or through VXIbus or RS-232 connection. A front
panel diagnostics connector on all three mainframes allows continuous local or remote system monitoring.
These mainframes comply 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 any of these
mainframes an excellent choice for all VXI test system applications.

Superior Cooling
The innovative cooling design of these three VXI mainframes 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.
For all three mainframes, 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)) operate at full capacity
at all times. In Variable Speed mode, the fan speed varies depending on the temperature 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.
