Electromagnetic Interference Considerations

Electromagnetic interference (EMI) from one instrument can adversely affect the
operation of nearby equipment. To prevent the TSG-3800 from interfering with other
equipment, it must be installed and operated as described in the following
paragraphs.
All cables connected to the TSG-3800 should be shielded with metal connector
shells. The connectors on the back of the unit are shielded and connected to Frame
Ground. The screws on all cable shells must be securely fastened to the connectors
on the shelf's rear panel.
While the TSG-3800 is in operation, a module or blank filler panel (item number
10977120-000-0) must be installed in every slot. Captive screws located at the top
and bottom of the module panel must be properly secured
Caution: To maintain EMC compliance, use only properly shielded
cabling on all telecom signal wiring, including I/O, clocks, and
Ethernet connections. Ensure that connections are appropriately
grounded.
