Carrier-band Network Monitor

The CBM-1 Carrier-band Network Monitor is a diagnostic and maintenance tool for mission-critical networks that have to operate continuously. It is used to observe network operation and measure signals while the network and the control system are active. The Monitor is a passive instrument that examines the network, but does not interfere with its operation in any way. It is a valuable management and maintenance tool for use by field personnel and does not require extensive knowledge of network technology.

The Monitor is used to:

  • Determine which stations (also called nodes or devices) are active on the network.
  • Measure the signal level of each station and display the current and low signal values.
  • Examine signal reflections that indicate damaged cabling or loose connections.
  • Measure noise to determine if there is noise pick-up or grounding problems on the network.

These measurements are used to verify that the network is operating correctly, or to detect deteriorating network conditions so that steps can be taken to prevent network down-time, or to help determine what has failed.
