One-path two-port
calibration
Method of calibration performed for reflection and
one-way transmission measurements, for example for
measuring S11 and S21 only. It ensures high accuracy
for reflection measurements, and mean accuracy for
transmission measurements.
Full two-port
calibration
Method of calibration performed for full S-parameter
matrix measurement of a two-port DUT. It ensures
high accuracy.
TRL calibration Method of calibration performed for full S-parameter
matrix measurement of a two-port DUT. LRL and
LRM types of this calibration are also supported. In
ensures higher accuracy than a two-port calibration.
Mechanical calibration
kits
The user can select one of the predefined calibration
kits of various manufacturers or define own
calibration kits.
Electronic calibration
modules
Electronic calibration modules manufactured by
PLANAR make the Analyzer calibration faster and
easier than traditional mechanical calibration.
Sliding load calibration
standard
The use of sliding load calibration standard allows
significant increase in calibration accuracy at high
frequencies compared to the fixed load calibration
standard.
Unknown thru
calibration standard
The use of an arbitrary reciprocal two-port device
instead of a zero-length thru during a full two-port
calibration allows for calibration of the test setup for
measurements of the non-insertable devices.
Defining of calibration
standards
Different methods of calibration standard defining are
available:
§standard defining by polynomial model
§standard defining by data (S-parameters).
Error correction
interpolation
When the user changes such settings as start/stop
frequencies and number of sweep points, compared to
the settings of calibration, interpolation or
extrapolation of the calibration coefficients will be
applied.
