The Site Master has two Type A USB connectors that accept USB Flash Memory devices for
storing measurements, setup data, and screen images.

The headset jack provides audio output from the built-in AM/FM/SSB demodulator for testing
and troubleshooting wireless communication systems. The jack accepts a 2.5 mm 3-wire
miniature phone plug such as those commonly used with cellular telephones.
LAN Connection (Option 411)
The RJ-45 connector is used to connect the Site Master to a local area network or directly to a
PC with an Ethernet crossover cable. Integrated into this connector are two LEDs. The amber
LED shows the presence of a 10 Mbit/s LAN connection when on, and a 100 Mbit/s LAN
connection when off. The green LED flashes to show that LAN traffic is present. For more
information on the LAN connection, Ethernet connection, and DHCP, refer to

Optical SFP (Option 751)
The optical transceiver port is used to connect the instrument to the fiber optic CPRI link
between a Remote Radio Unit (RRU) and a Base Band Unit (BBU). The port is present only
on instruments with Option 751 installed. It accepts SFP modules that support line rates of
650 Mbps up to 9.83 Gbps. Refer to the instrument’s Technical Data Sheet for transceiver
part numbers and specifications.

connected to a three-wire power line outlet. If power is supplied without grounding
the equipment in this manner, then the user is at risk of receiving a severe or fatal
electric shock.
