Step-5 : Install a Chassis Shield
If EMI shielding is needed, install the Agilent E1409A/B Chassis Shield
according to the instructions in the Agilent E1409A/B Installation Manual.
This shield is the Agilent Technologies implementation of Section B.7.3.4
of the VXIbus Specification (Revision 1.3) that allows grounded shielding
between mainframe slots. Typical applications for the chassis shield
include isolating modules that generate electro-magnetic interference (EMI)
at excessive levels, and shielding modules from noise sources during
sensitive measurements.
The chassis shield assembly contains a plated-steel shield with four
conductive chassis shield guides and mounting hardware. Two
adhesive-backed thermoplastic insulators are also included and can be
attached to the chassis shield if desired. Since the chassis shield fits
between slots in the mainframe, you do not lose the use of a slot by
installing the shield.
