The DOCSIS 3.0 DSP 860 is a portable cable analyzer that can be used to determine the strength and signal quality of analog, digital HSD, and VoIP services, according to the product's official site. If your device is not working properly or detecting a weaker signal strength than is actual being emitted, it my be malfunctioning. Before you send your device off for repairs, run through a list of troubleshooting techniques to narrow the list of problems and potentially resolve the issue yourself.
Instructions
1. Upgrade the upstream bandwidth that will be the device. If the device does not receive enough bandwidth, it is unable to process a cable with a very high signal strength. The overwhelming amount of traffic submitted by the cable can cause the device to give a very inaccurate reading, if one at all.
2. Utilize the "Test Meter" button on the device. If the test meter reads lower than a 64 QAM signal source, you likely have a problem with your antenna that can only be corrected by the device's manufacturer.
3. Complete a system sweep of the device's operating system. Resetting the device back to its factory state is a good maintenance habit, as well as a useful troubleshooting technique. If a glitch has occurred within the device's software, you can completely restore the device back to its state when you first open its back, hopefully eliminating any errors in the process.
