Arcom Digital Quiver XT User Manual page 28

As an alternative connection methodology, the NTC TDR can be connected directly
to a line passive where the forward and return connection is made by using the QTP-20,
a 20dB 2 port test probe connected directly to the center conductor via the seizure screw
access port as shown below.
The spread spectrum probing signal transmit signal can be set from -10 .. +10dBmV,
the recommended and default level is 0dBmV. This signal level range is considered safe
and will not be disruptive to any traffic. As will be described, with one button the return
spectrum analyzer can be access such that the user can easily confirm that the probing
signal level are below the return noise floor and that they are invisible.
