General Product Information
Error Terms
Typical Cause of Failure
The calibration kit load or a bad “thru” cable is the most common cause of load
match specification failure.
If the load and “thru” cable performance are independently verified, the
analyzer requires repair. Refer to “Shipping Your Network Analyzer for Service
or Repair” on page 1-3.
Reflection Tracking (E
RF
and E
RR
)
Reflection tracking is the difference between the frequency response of the
reference path (R1 or R2 path) and the frequency response of the reflection test
path (A or B input path). These error terms are characterized by measuring the
reflection (S
11
, S
22
) of the open and the short during the measurement
calibration.
All reflection measurements are affected by the reflection tracking errors.
Typical Cause of Failure
The calibration kit open or short is the most common cause of reflection
tracking specification failure.
If the open or short performance has been independently verified, the analyzer
requires repair. Refer to “Shipping Your Network Analyzer for Service or
Repair” on page 1-3.
Transmission Tracking (E
TF
and E
TR
)
Transmission tracking is the difference between the frequency response of the
reference path (including the R input) and the frequency response of the
transmission test path (including the A or B input) while measuring
transmission. The response of the test port cables is included. These terms are
characterized by measuring the transmission (S
21
, S
12
) of the “thru”
configuration during the measurement calibration.
All transmission measurements are affected by the transmission tracking
errors.
Typical Cause of Failure
The test port cable is the most common cause of transmission tracking
specification failure.
If the test port cable performance has been independently verified, the
analyzer requires repair. Refer to “Shipping Your Network Analyzer for Service
or Repair” on page 1-3.
Isolation (E
XF
and E
XR
)
Isolation, or crosstalk, is the uncorrected forward and reverse isolation error
terms that represent leakage between the test ports and the signal paths. The
isolation error terms are characterized by measuring the transmission (S

,
