Click to enlarge image WinTV Digital Signal Strength Monitor OverviewThe WinTV Signal Strength Monitor displays the relative strength of the digital signal on the channel you are tuned to. It will show the Signal to Noise ratio, the number of Received Errors and the number of Uncorrectable errors.The Digital Signal Monitor will not work with analog TV channels. It will work with ATSC and QAM digital TV channels, plus DVB TV channels, on most Hauppauge digital TV tuner boards.The Signal Monitor is a handy tool which can be used to either adjust your digital TV antenna, or when used with digital cable TV, to know if your digital signal is too weak to receive a signal without distortion.Using the Signal Monitor to adjust a digital TV antenna:Look at the Received Errors indicator, and position your antenna to minimize the number of errors. Once you have positioned your antenna, take a look at Uncorrectable Errors. If it is 0, you will get a digital TV picture without any distortion. If you have Uncorrectable Errors after positioning the antenna, the digital TV signal is too weak to receive a Digital TV program without distortion. In this case, you might want to consider an antenna 'booster' or a better TV antenna.Using the Signal Monitor to monitor the quality of a digital TV channel:If you are watching a digital TV channel which is on cable TV (often called 'clear QAM'), you can use the WinTV Signal Strength Monitor to see the reception quality of that channel.
If the number of Uncorrectable Errors is 0, then you should see a undistorted TV picture. If there are Uncorrectable Errors, your TV picture will have some amount of distortion.
The WinTV Digital Signal Strength indicator displays information about the quality of the digital TV channel you are watching. This application is used with the WinTV v7 and WinTV v8 applications.Click. Installation:Download and run the signal strength install program. Once installed, you will find a program called Signal Monitor in the WinTV Program group. Its program name is hcwSigMon.exeAfter running the WinTV Signal Strength Monitor, if you minimize it you will see an icon on the status bar on your PC screen (normally this is in the lower right side of your monitor screen). It will show you the colors of the signal strength. Using the Digital Signal Strength MonitorThe colors / levels indicate a measurement of the SNR (signal to noise ratio):The higher the SNR number, the better your digital TV reception will be.
We have color coded rececption quality to make it easier to determine how good your digital TV reception is:SNR indicator:Green - optimal signal levelYellow - O.K. Signal levelOrange - Poor signal levelRed - no signalYou will have the best reception of the digital TV signal if Uncorrectable Errors is 0. A number of Received errors will not affect your digital TV reception, as long as the Correctable Errors is 0. We display the Received Errors so that you can better orient your digital TV antenna.If you minimize the WinTV Signal Strength Monitor, you will see an icon on the status bar on your PC screen (normally this is in the lower right side of your monitor screen). It will show you the colors of the signal strength.Notes:. The Faster/Slower indicator tells the WinTV Digital Signal Stregth monitor how often to check the signal.
The default is once per second. You may notice that you can have 'received errors' without any loss of quality of the video stream.

This is normal. However, when you have 'uncorrectable errors', that is when your video stream will suffer. Some of the digital TV hardware decoders used on the various WinTV boards do not have all of the Status indicators in the picture above. This does not affect the signal reception.

If your product does not have a status indicator, it will be greyed out.
