What should be done about frequency response variations of less than 1 dB in injected test carriers?

• A. Keep the test carriers off the node
• B. Document the variations for future reference
• C. These variations are normal and can usually be disregarded
• D. Adjust the settings to eliminate variations

Answer: (C)

Frequency response variations of less than 1 dB in injected test carriers are generally considered to be within acceptable limits in many testing scenarios. Such small variations are typically regarded as insignificant because they fall within a noise floor that commonly exists in most systems. Therefore, these minor fluctuations often do not adversely affect the overall performance or quality of the signal being tested. Recognizing that these variations can be regarded as normal allows engineers and technicians to focus on more significant issues that may affect system performance rather than spending time troubleshooting these minor discrepancies, which do not represent a real problem. Understanding this principle helps maintain efficiency in testing processes and resource allocation. This perspective distinguishes these minor variations from more substantial discrepancies that could indicate underlying problems or the need for adjustments. Therefore, accepting that variations of less than 1 dB can usually be disregarded aligns with standard practice in the field.
