MEASURING INSTRUMENT CALIBRATION The measuring equipment utilized to perform the tests documented in this report has been calibrated in accordance with the manufacturer's recommendations, and is traceable to recognized national standards. 4.2. SAMPLE CALCULATION Where relevant, the following sample calculation is provided: Field Strength (dBuV/m) = Measured Voltage (dBuV) + Antenna Factor (dB/m) + Cable Loss (dB) – Preamp Gain (dB) 36.5 dBuV + 18.7 dB/m + 0.6 dB – 26.9 dB = 28.9 dBuV/m 4.3. MEASUREMENT UNCERTAINTY Where relevant, the following measurement uncertainty levels have been estimated for tests performed on the apparatus: PARAMETER UNCERTAINTY Worst Case Conducted Disturbance, 3.84 dB 9KHz to 0.15 MHz Worst Case Conducted Disturbance, 3.65 dB 0.15 to 30 MHz Worst Case Radiated Disturbance, 3.15 dB 9KHz to 30 MHz Worst Case Radiated Disturbance, 30 5.36 dB to 1000 MHz Worst Case Radiated Disturbance, 4.32 dB 1000 to 18000 MHz Worst Case Radiated Disturbance, 4.45 dB 18000 to 26000 MHz Worst Case Radiated Disturbance, 5.24 dB 26000 to 40000 MHz Uncertainty figures are valid to a confidence level of 95%.
