1-P ort Calibration
1-P ort Calibration
This calibration error model provides the best accuracy for measurement of a 1-port device ,
providing full vector error correction for directivity , source match, and reection signal path
frequency response . The procedure uses three standards , usually a shielded open circuit, a
short circuit, and a load. Refer to Figure 5-8.
Figure 5-8. Calibration Setup for 1 P ort Cal
During the 1-P ort calibration, all standards are connected at the test port (the point at which
the DUT will be connected during normal measurements). 1-P ort calibrations are only available
with P ARAM 1. However , you can redene P ARAM 1 to ratio any two inputs you desire .
Figure 5-9 shows the error model for transmission/reection response and isolation errors .

Standards Required for a 1-P ort Calibration
The 1-P ort calibration sequence requires a minimum of three standards , an open, a short, and
at least one standard from the Loads menu.
