In order to measure the coupling factor, a 50 ohm signal source and 50
ohm measuring instrument are needed. These may be separate
instruments or may be combined into a single instrument, such as a network
analyzer, or spectrum analyzer with tracking generator.
Also needed are the ADA-515-CLEM 150 ohm to 50 ohm Adapter Pair with
the 68 cm length, 4 mm diameter copper rod, along with a 50 ohm
termination.
A typical test setup for instrument normalization and measurement of
coupling factor is illustrated in Figure 12. For coupling factor measurements,
the height of the 4 mm copper rod must be adjusted to be in the bottom
position of the clamp opening (see section 4.3).
The coupling factor, at each test frequency, is equal to the measured
amplitude difference between the normalization setup and the
measurement setup shown in Figure 12.
No limits are defined for coupling factor. Typical CLEM-6146 EM Clamp
data are shown in Figure 5 of the present document.
Typical performance curves for three (3) different clamps are provided in
Figure A.11 in Edition 4.0 of IEC 61000-4-6.
