Signal Type
The 830R can detect two types of signals:
• Active signals that are placed on a target cable with a transmitter.
• Passive signals that reside on the target cable.
Active
There are three ways to place active signals on a target cable with a transmitter:
• Direct connection (preferred method) requires a connection to be made directly onto target cable.
• Inductive requires placing an optional inductive clamp around target cable.
• Induction (broadcast) method uses a built-in antenna to broadcast a signal onto cables near the
transmitter.
Passive
Power cable signals can be detected passively without a transmitter if optional power mode is installed.
Recommended Settings
Choose transmitter power level according to how the signal will be placed on the cable.
