Used when the instrument is used as a tester and the receiver is the only
device connected to the line. The input impedance is nominal.
BridgedBridged

traffic. Please observe that this way of connecting may disturb the monitored
line - connection through a protected monitor point, as well as using the input
mode MonitorMonitor, is recommended instead.
MonitorMonitor
