VF Noise
The VF Noise test allows you to
measure the amount of unwanted or
disturbing energy introduced into a
loop from man-made and natural
sources.
Each parameter is described below.

Termination is either BRIDGING if
the unit uses high bridging
impedance when the cable is
active or terminated by other external equipment, or TERMINATED if
the unit uses normal test impedance termination.
³
Noise Filter is either PSOPHOMETRIC for ITU standard or C-MESSAGE
for ANSI standard.
