7.5
Calibration
There are eight types of calibration methods to reduce the system errors, as follows:
•
Normalizing.............................
(Refer to sub-section 7.5.1 and (1), (2) of sub-section
•
Normalizing &
Isolation calibration ..........
(Refer to sub-section 7.5.2 and (3) of sub-section 7.5.5.)
•
1-port full calibration ...............
(Refer to sub-section 7.5.2 and (4) of sub-section 7.5.5.)
•
2-port full calibration ...............
(Refer to sub-section 7.5.4 and (5) of sub-section 7.5.5.)
•
3-port full calibration ...............
(Available only when OPT 11/14 is installed. Refer to
Section 7.5.11.)
•
4-port full calibration ...............
(Available only when OPT 14 is installed. Refer to Section
7.5.11.)
•
Averaging................................
(Refer to sub-section 7.4.10.)
•
Smoothing...............................
(Refer to sub-section 7.4.10.)
The methods of

and
are used to remove error factors which can be
reproduced. These methods measure the standard whose real value has been known. The result
is used to obtain the real value of the measurement according to the error model.
The methods of
and
are used to statistically reduce random errors by obtaining the time
average and moving average respectively.
In addition, when using the R17050 automatic calibration kit is,
,
,
and
can be calibrated
by a simple operation. For more information, refer to the R17050 Automatic Calibration Kit
operation manual.
Note:
The calibration methods of
,
,
,
,
and
can not be performed simultaneously.
Since the methods of
and
can be independently operated, they can be performed
simultaneously.
7.5.1
Normalizing
Calibrates the frequency characteristics of the magnitude and phase. This method can be easily
performed but cannot obtain a high accuracy.
(1)
For measuring transmission
Calibrates the frequency characteristics including that of the connection cable and connec-
tor by connecting the through standard with the condition where any sample is removed.
