Calibration Interpolation
Calibration interpolation is always active. The analyzer automatically recalculates the
error coefficients when the test frequencies or the number of points have changed. The
resulting frequency range must be within the frequency range used during the user
calibration. If this is not the case, the analyzer reverts to the factory default calibration.
When calibration interpolation is used, the analyzer displays the C? annotation. System
performance is not specified for measurements using calibration interpolation.
Available Calibrations
ES models only
• Two-Port Calibration
Compensates for frequency response, load match, source match, and directivity
errors while making S-parameter measurements of transmission (S
21
, S
12
) and
reflection (S
11
, S
22
). Compensates for crosstalk when the softkey
is toggled ON. Requires open, short, load, and through standards.
ET and ES models: transmission measurements
• Normalization
Simultaneous magnitude and phase correction of frequency response errors.
Requires a through connection. Used for both narrowband and broadband detection.
Does not support calibration interpolation.
• Response
Simultaneous magnitude and phase correction of frequency response errors.
Requires a through connection.
• Response and Isolation
Compensates for frequency response and crosstalk errors. Requires a load
termination on both test ports and a through standard.
• Enhanced Response
Compensates for frequency response and source match errors. Requires open, short,
load and through standards.
ET and ES models: reflection measurements
• One-Port calibration
Compensates for frequency response, directivity, and source match errors. Requires
an open, short, and load standards.
