EMC Filler Panel (1-slot wide)

The Agilent E8400-60202 filler panel (1-slot wide) provides

continuous EMC connection across the mainframe front

opening. This helps reduce radiated emissions and

increases ESD immunity. All Agilent VXI modules include

EMC contacts to adjacent slots.

VXI Slot Filler Panel (1-slot wide)

The E8400-44305 VXI Slot Filler Panel is 1-slot wide and is

used to cover unused slots, providing a smooth appearance

and preventing access. In addition to the cosmetic and

safety value, the slot filler panel suppresses acoustic noise

and improves airflow. The E8400-44305 does not include

EMC contacts.

Air Flow Restricter (1-slot)

The one-slot E8400-80917 Air Flow Restricter blocks airflow

in one empty slot.

Intermodule Chassis Shield Kit (1-slot wide)

The E8400-80919 Chassis Shield Kit (1-slot wide) provides

additional shielding between noisy modules. These shields

are relatively easy to install.

Documentation

Mainframe documentation consists of a User/Service

Manual which describes electrical and mechanical aspects

of the mainframe and accessories. The manual is included

on Agilent’s Universal Instrument Drivers CD-ROM supplied

with the mainframe and is also available on Agilent’s

Website. A printed copy of the manual is also included.

Warranty

Agilent Technologies provides a standard 3-year return-to-

Agilent warranty on this mainframe. E8408A Opt. W01

converts the standard warranty to 1-year On-Site.

1. Specifications apply at the mainframe backplane, 0 - 55° C.

2. I

= Rated mainframe peak dc output current as defined by the VXIbus

Specification.

3. I

= Rated mainframe peak-to-peak dynamic current as defined in the VXIbus

Specification by a current vs. frequency curve.

4. +5V must have a 1.0 A minimum load for other supplies to be in regulation

specification.

5. Maximum +5V current can be increased if -5.2V load is less than 2.0 A maximum or

-2V load is less than 2.0 A maximum. Maximum = 17.0 A + 1.2*(2.0 A - Load on -5.2V) +

0.4*(2.0 A - Load on -2V).

6. Maximum +12V current can be increased if -12V load is less than 2.0 A maximum.

Maximum = 2.7 A + 1.2*(2.0 A - Load on -12V).
