Measurement
Uncertainty
The following graphs show typical measurement uncertainty. The
assumptions made to generate these curves were:
l
For transmission uncertainty, the DUT is assumed to be well-matched.
l
For reflection uncertainty, the DUT is assumed to be a one port device. (In
other words, load match errors produced when measuring transmission are
not taken into account.)
0
Power
=
0
dBm
for reflection measurements
0
Power = -20
dBm
for transmission measurements
l
For transmission measurements, an enhanced response calibration was
performed.
l
For reflection measurements, a one port calibration was performed.
