Composer Elite Operating Manual
2.1.2.4 Electrical Interference Reduction
When Composer Elite is integrated into a deposition system, each cable
connection is a potential path for electrical noise to be conducted to the Sensor
Control Unit or Acoustic Sensor. The possibility of external electrical interference
problems can be greatly reduced by adhering to the following guidelines:
 Make certain the Sensor Control Unit and Acoustic Sensor are properly
grounded. (Refer to section 2.1.2.3, Composer Elite System Grounding
Requirement, on page 2-4.)
 Make certain the Sensor Control Unit covers and option panels are in place and
secured with the provided fasteners.
 Use shielded cable as short as practical for remote communications.
 Avoid routing the Composer Elite Interconnect cable and communications
cable near areas that have the potential to generate high levels of electrical
interference. For example, large power supplies can be a source of large and
rapidly changing electromagnetic fields. Placing cables at least 30 cm (1 ft.)
from these problem areas can result in a significant reduction
of electrical interference.
