Step 13. Enter the attenuator metrology data information in the Worksheet provided as
Actual Attenuation using equation 1.
Step 14. Calculate the Measured Attenuation and enter the values in the Worksheet using
equation 2.
Step 15. Use the Actual and Measured attenuations given in the Worksheet to calculate the
Actual and Measured Noise Figures in the Test Record.
Step 16. Calculate the Noise Figure Instrument Uncertainty Error for each ENR
measurement range detailed in the relevant model number tables in Appendices A
through D. Enter the values into the appropriate test record and ensure that the
measured values are within their published specifications (pass/fail).
