Instrument Overview 2-6 Test Panel Connector Overview
Cell Master UG PN: 10580-00250 Rev. K 2-11
RF Out (Reflection In)
RF output, 50 Ω Type-N female connector, for reflection measurements. Maximum ouput and
damage level are provided in the Technical Data Sheet (refer to Appendix A).
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
Type-N connector. Do not overtighten the connector. The recommended torque is 12 lbf·in to
15 lbf·in (1.36 N·m to 1.70 N·m).
GPS Antenna Connector
The GPS antenna connection on the Cell Master is type SMA-female. GPS function is
described in Chapter 6, “GPS (Option 31) ”.
To prevent damage to your instrument, do not use pliers or a plain wrench to tighten the
SMA connector. Do not overtighten the connector. The recommended torque is 8 lbf·in
(0.9 N·m or 90 N·cm).
Rx, Tx, E1 Connectors
These ports are used in T1/T3/E1 operations described in the Backhaul Measurement
Guide (PN: 10580-00238) available on the documentation disc. Refer to
Appendix A, “Measurement Guides” for additional information.
To prevent damage to your instrument, do not use pliers or a wrench to tighten the T3 BNC
connectors. Do not overtighten the connectors.
Digital Signal Output (DVB ASI Out) BNC Connector
The digital signal output, BNC female connector is unique to the Bit Error Rate (BER)
options (Option 57 and Option 79) and is present only when one or both of these options are
installed. The Digital Television Signal Analyzer options operations are described in the
Digital Television Signal Analyzer Measurement Guide (refer to Appendix A).
To prevent damage to your instrument, do not use pliers or a wrench to tighten the BNC
connector. Do not overtighten the connector.
The DVB-ASI function produces MPEG-TS data output during a BER measurement. This
output can be connected to MPEG-TS analysis equipment to monitor video errors or can be
connected via an appropriate ASI to USB demultiplexing and decoding accessories for
channel identification and monitoring purposes.
