Meaning
Formal records generated by a certified testing facility during electromagnetic compatibility or radio frequency evaluations. These accredited chamber logs provide a chronological account of every test step and equipment setting maintained throughout a certification session. The documentation verifies that the test environment met the specific requirements of the regulatory body.
Verification Duty
Accuracy in these records ensures that a product qualification is defensible during a technical file audit. Measurement data from the radio testing equipment must align with the timestamps in the log. If a discrepancy appears, the validity of the entire test report comes into question.
Quality Control
External auditors examine the sequencing of entries to confirm that the calibrated antenna remained at the correct distance from the device under test. Standard operating procedures dictate how a technician records an interruption or a hardware reset. This process prevents the omission of failures or the unauthorized adjustment of equipment parameters.
Without these details, a lab cannot prove that the background noise floor remained below the limit for the duration of the scan.
Data Retention
Secure storage of the raw capture files and manual annotations protects the integrity of the submission against claims of data manipulation. A laboratory maintains these logs as the primary evidence of the physical test event. The presence of a signature from the overseeing engineer completes the document.
