Electromagnetic Interference (EMI) Considerations
Electromagnetic interference (EMI) from one instrument can adversely affect the
operation of nearby equipment. To prevent the SSU-2000e from interfering with
other equipment, it must be installed and operated as described in the following
paragraphs.
All cables connected to the SSU-2000e should be shielded with metal connector
shells. The connectors on the front of the chassis are shielded, with the shields
connected to frame ground. Follow local procedures for shield grounding. The
screws on all cables must be securely fastened to their corresponding connectors
on the unit. While the unit is in operation, there must be a module or blank filler
panel installed in every slot. Ensure that the captive screws located at the top and
bottom of the module panel are properly secured.
