5.2.2.12 Headphones Connector
The R&S FPL1000 provides demodulators for AM, FM and PM signals, which can be
routed to the headphone connector. With headphones or an external loudspeaker con-
nected to the 3.5 mm headphone socket, the displayed signal can be identified acousti-
cally.
This connector is only available if the R&S FPL1-B5 option is installed.
Note the safety information provided in "Connecting headphones" on page 11.
For details, see "Data Output" on page 300.
