Coax Noise Reach Calcs
The “Spatial Engineer 11” tutorial video on coax noise reach calculations offers an in-depth guide for telecommunications engineers and technicians on assessing and planning for noise levels within a coaxial cable network. This process is crucial for ensuring that signal quality is maintained across the network, especially when extending services through neighborhoods or other new areas. Here’s a summary of the key steps and concepts covered in the video:
- Checking Network Connectivity:
- The first step involves verifying that the network’s connectivity is intact. This can be done using the feature pull-down menu to display connectivity. It’s important to ensure that the guide map only displays the relevant network sections to avoid tracing unrelated paths.
- Accessing Noise Reach Calculations:
- After confirming good connectivity, the next step is to access the noise reach calculations feature located under the coax menu. This tool is designed to help predict how far a signal can travel before noise diminishes its quality to unacceptable levels.
- Setting Configuration and Design Mode:
- Prior to performing noise reach calculations, it’s necessary to have completed the design modes setup in the DBA along with the equipment configuration. For the example, a 1 GHz digital distribution setup at Cascade level one is used.
- Performing Noise Reach Calculations:
- The calculation process begins by selecting the noise reach option, which then prompts for a boundary to be drawn around the area of interest (in this case, the pole line neighborhood). This boundary helps define the area over which the noise calculations will be performed.
- After drawing the boundary, users are asked to select a starting point for the calculations, typically where the launch amplifier is situated.
- Interpreting Results:
- The initial calculation at Cascade level one indicated insufficient signal level for the designated reach. By adjusting the Cascade level to two and repeating the calculation process, a successful result was achieved, indicating that two amplifiers would be required for adequate signal distribution in the tested area.
- Conclusion:
- The tutorial concludes by emphasizing the straightforwardness of performing noise reach calculations within Spatial Engineer 11. This functionality enables network planners to efficiently determine the necessary cascade level and amplifier placement to ensure optimal signal quality across the network.
- Looking Ahead:
- The presenter mentions that the next video will cover automated design, hinting at further exploration into Spatial Engineer 11’s capabilities for simplifying and optimizing network design tasks.
This tutorial is part of a series aimed at providing users of Spatial Engineer 11 with practical knowledge and tools for designing and managing coaxial cable networks. By focusing on noise reach calculations, this video addresses a vital aspect of network planning, ensuring that signal integrity is maintained throughout the network’s extent.
