NOTE Response calibration is not as accurate as other calibration methods.
Corresponding
Measurement
Transmission or
reflection
measurement when
improved accuracy is
desired. Not as
accurate as 2-port
calibration.
Reflection of any
one-port device or
well terminated
two-port device.
Reflection of any
one-port device or
well terminated
two-port device.
Transmission or
reflection of highest
accuracy for two-port
devices.
Transmission or
reflection in
noncoaxial
environment such as
in a fixture or
on-wafer.
Transmission or
reflection in
noncoaxial
environments. More
accurate than
TRL*/LRM*.

response for
reflection. Frequency
response, source
match, and isolation
for transmission.
Enhanced reflection
corrects for load
