Question: 1 / 400

A Signal Reference Grid (SRG) provides shielding for?

Low frequencies

EMF from power cables

Grounding of equipment

High frequencies

The Signal Reference Grid (SRG) is specifically designed to provide shielding against high frequencies. When dealing with electrical systems, particularly in data centers, high-frequency signals can induce noise and interference, which can compromise the performance of sensitive electronic equipment. The SRG serves to mitigate these effects by creating a low-impedance surface that helps to shield against unwanted electromagnetic interference (EMI) at higher frequencies, ensuring that data integrity is maintained.

Additionally, the SRG plays an essential role in establishing a uniform grounding reference for equipment, which is crucial for maintaining stability and reducing noise. However, its primary function is centered around high-frequency signaling, making it a critical component in the design and operation of facilities that require robust electromagnetic compatibility.
