Connecting to the Network
ProBER 2 provides 75Ω unbalanced and 120Ω balanced transmit and receive
interfaces. For details of the connectors, see "Connecting to the Network" on
page 2-7.
To prevent distortion of the results only connect cables to one of the Transmit or
Receive ports i.e. 75Ω or 120Ω.
The receive interface termination can be:
Terminated - 0 dB Gain
Monitor 20 dB Gain - to compensate for a low level signal at a network
equipment monitor point.
Monitor 26 dB Gain - to compensate for a low level signal at a network
equipment monitor point.
Monitor 30 dB Gain - to compensate for a low level signal at a network
equipment monitor point.
Bridged - high impedance.
ProBER 2 also provides a 75Ω EXT CLOCK IN port which accepts a 2 MHz clock
source complying with ITU-T G.703 Section 10 (Reference 1).
