Unless otherwise specified, the standard range of atmospheric
conditions for marking measurements and tests is as follows:
Ambient temperature: 20 ± 15°C
Relative humidity:
65 ± 20%
If there may be any doubt on results, measurements shall be made within the following limits:
Ambient temperature: 20 ± 2°C
Relative humidity:
65 ± 5%
6-2 Measurement Method of L and Q
Test equipment:
Fixture:
Measuring frequency:
Hewlett Packard RF Impedance analyzer 4191A
Hewlett Packard Test fixture 16092A
500 MHz/1.0nH ~ 22nH (1.0nH ~ 15nH)
200 MHz/27nH ~ 100nH (18nH ~ 27nH)
1. Perform auto-calibration to the HP4191A .275" (7mm) unknown connector connected to
0Ω/0S/50Ω standard terminations.
2. Connected the test fixture 16092A.
Measure the open circuit admittance (Go, Bo), and the short circuit impedance (Ro, Xo).
