Since the shut-off of analog signals, most broadcasters have received calls from viewers regarding their inability to receive the station's signal. The quick answer is to check the theoretical footprint and assure viewers that they should be getting a good clean signal, and ask them to adjust their antenna or check the setup on their receiver. But after the call, a broadcaster is left wondering how the RF signal quality really is in a certain area.

When investigating reception complaints, there is a more productive approach to take since most broadcasters are monitoring and testing all video and MPEG signals in their facilities. They can simply extend this monitoring function to analyze the transmitter's RF signal and specific viewer locations. The RF leg in the signal chain is vital to ensuring quality and reliable reception.

Tools for taking 8-VSB measurements are available in different forms, including handheld SLMs and USB PC probes. They show and quantify problems, and also relate reception difficulties to their causes. These simple measurements can also point to transmitter or transmit antenna issues that may require attention.
