Conditions
Return loss measurement has been carried out with Neutrik NBNC75BTU11 75 Ω BNC connectors.
To compare the results of the Neutrik connectors, we have chosen the BNC connectors of a European
manufacturer (Standard series & HD optimized series), whose products are widely spread in broad-
cast applications across Europe, as reference.
All tested cable assemblies have been terminated with 20 m of the well-known Belden 1694A 75 Ω
coax cable.
a) Single cable (length 20m) with both ends terminated for connector evaluation
SMPTE 424M

SMPTE 424M
3
specifies a return loss of better than 10 dB between 1.485 GHz and 3 GHz and better
than 15 dB from 5 MHz to 1.485 GHz (values below SMPTE limits are indicated red in Figure 4).
All test specimens were sweep tested up to 4.5 GHz.
