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. |
