Calibration
Specifying Different Standard for Each Frequency
Example 4-2 When frequency ranges specified with subclasses do not cover a part of a
measurement frequency range
For a measurement frequency range (1 GHz - 8 GHz), if you execute calibration with a
standard of subclass 1 (1 GHz-5 GHz) and then with a standard of subclass 2 (6 GHz-8
GHz),
Done
is not available for the undefined portion (5 GHz-6 GHz).
Figure 4-58 When a part of a frequency range is not covered
Example 4-3 When a frequency range specified with a subclass lies outside the measurement
frequency range
For a measurement frequency range (1 GHz - 5 GHz), if you define a standard of subclass
1 (1 GHz - 5 GHz) and a standard of subclass 2 (5 GHz-8 GHz), calibration possible for
subclass 2 although it is out of the measurement frequency range. The calibration
coefficients, however, are disregarded. (There is no check mark on the softkey.) Note that,
because the standard of subclass 1 covers the measurement frequency range,
Done
is
available.
