Entering Calibration Uncertainties
Entering Calibration Uncertainties
The Uncertainties window allows you to enter the values that will be used
for calibration uncertainty calculations.
Note: This information is kept in memory when using the template option as
explained in Selecting the Calibration Option on page 60.
To establish total uncertainty, the components are divided into the
following:
³
The Calibration (Reference) Power Meter uncertainty
³
Type A uncertainties
³
Type B uncertainties
The Calibration (or Reference) Power Meter uncertainty is provided in the
IQS-1500 Power Meter’s calibration report and must be at a 95 % (2σ)
confidence level. For example, if the confidence level is specified at
68 % (1σ), you must multiply the uncertainty by a factor of 2.
