Enhanced Reflection Calibration
The enhanced reflection calibration is activated by selecting
the
ENHANCED RESPONSE
The enhanced reflection calibration effectively removes load match error from the
enhanced response calibration performed on a bilateral device. A bilateral device has an
identical forward (S

as filters, attenuators, or switches) are bilateral. Some passive devices (circulators,
isolators) and most active devices do not have identical forward and reverse transmission
responses and enhanced reflection calibration will not work with these devices.

softkey within the calibrate menu, provide directivity, source match, and
frequency response vector error-correction for reflection measurements. These procedures
provide high accuracy reflection measurements of one-port devices or properly terminated
two-port devices.

Full Two-Port Calibration (ES Models Only)

The full two-port calibration, activated by pressing the
calibrate menu, provides directivity, source match, load match, isolation, and frequency
response vector error-correction, in both forward and reverse directions, for transmission
and reflection measurements of two-port devices. This calibration provides the best
magnitude and phase measurement accuracy for both transmission and reflection
measurements of two-port devices, and requires an S-parameter test set.
In this type of calibration, both forward and reverse measurements must be made. You
have the option of setting the ratio of the number of forward (or reverse) sweeps versus the
number of reverse (or forward) sweeps. To access this function, press
and enter the number of sweeps desired.

TRL*/LRM* Two-Port Calibration

The TRL*/LRM* two-port calibration, activated by pressing the
softkey within the calibration menu, provides the ability to make calibrations using the
TRL or LRM method. True TRL/LRM calibration is available on analyzers equipped with
Option 400, the Four Sampler Test Set. For more information, refer to
