36 N9069C Noise Figure Measurement Guide
Making Noise Figure Measurements
Calculating Measurement Uncertainty
6.
The noise figure measurement uncertainty of the current measurement result is displayed in
the
Noise Figure Uncertainty. 2
σ
and
Sweep Uncertainty
areas. Three types of measurement
uncertainty are provided; User Cal, Internal Cal, and Uncalibrated. For more information about user
cal and internal cal, you can refer to
“User Cal vs. Internal Cal” on page 59
.
— The
Noise Figure Uncertainty. 2
σ
area shows uncertainty results for the current settings.
— The
Sweep Uncertainty
area shows sweeping uncertainty results for a parameter that can be set
in the
Sweep
area. You can see the impact of different parameters to the uncertainty results
through this display.
7.
(Optional) In the
Sweep
area, select
another sweep parameter, and set the
ranges by entering the
Lower
and
Upper
values.
