should kept minimum. The Com-Power CDN coupling factor is
almost 0 dB for the entire frequency of 150 kHz - 80 MHz.
3.0 Measuring these factors on site
Typically, the common mode terminal impedence, attenuation
and coupling factors are measured at the factory and supplied
with each unit. However if you wish to check the attenuation
and coupling factor on site you could purchase optional
calibration kit which includes the shorting bars, set of 150
Ω
-
50 Ω adapters and 50 Ω adapter. You will aso need calibration the
shorting bars for making level measurements described in section
4.0 (part# CK-CDNAF4RCA).
The common mode impedance
measurement is made using appropriate network analyzer.
