Measurement parameters for this example are:
Measurement frequency:
Displayed signal amplitude:
Reference level:
Resolution bandwidth:
Input attenuation:
Antenna VSWR
Test-Set VSWR
*Approximately 62 dB  V for the EMC analyzer. The EMC analyzer
reference level is found by turning o the correction data on the
EMC analyzer ( ,

underlined).
The measurement uncertainties are found in HP 8590 EM Series EMC
Analyzer Calibration Guide . The measurement uncertainties for the
EMC analyzer using the instrument settings above are:
Calibrator uncertainty:
Calibration repeatability:
Receiver atness uncertainty:
Receiver attenuator uncertainty:
Reference level uncertainty:
Resolution bandwidth switching uncertainty: 0.4 dB
Receiver scale delity uncertainty:
The measurement uncertainties for the HP 84125A/B test set are
found in Test Set and Antenna Factor Accuracy speci cations found
earlier in this chapter. The measurement uncertainties for the HP
84125B test set using the measurement parameters above are:
Antenna factor uncertainty
Antenna / test-set mismatch uncertainty
Calibration data uncertainty
Test-set atness uncertainty
Test-set repeatability uncertainty
Test-set maximum temperature drift
Table A-1 lists the uncertainties along with the required information to
calculate the measurement uncertainty. Refer to NAMAS, Publication
NIS 81 for the procedure on calculation of standard errors.
