Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 28 DTVision Eye Screen I-Signal Eye Display Graphic display of the eight data amplitude levels. This can be used to monitor the demodulated 8VSB signal. When signal is precise, the seven vertical "eyes" will appear (this display shows two sets). Linear or non-linear distortion in the modulator process will cause incorrect I-signal amplitude at center of "eye" pattern. Transmitter distortion such as group delay, frequency tilt, or ripple will cause the "eye" to close and result in receiver data errors. . Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 29 Linear Equalizer Graph Linear Equalizer Display: This display shows the characteristics of the linear adaptive equalizer. The horizontal axis is frequency (0 to 5.38 MHz). There are two traces on this display. One shows the amplitude of the equalizer's response in decibels, and the other shows the group delay of the equalizer in nanoseconds. The vertical scale for the amplitude display is along the left side of the display. The range is always –3 to +3 decibels. The group delay scale automatically scales itself to the equalizer data, and the minimum and maximum values appear along the right side of the scale. Since this display shows the equalizer characteristics, the channel (transmitter) characteristics, which are being corrected, will be the inverse of the equalizer. For example, if the equalizer shows a rising amplitude response with increasing frequency, then the transmitter has a falling amplitude response with increasing frequency. The same inverse relationship also holds with respect to group delay. In normal operation, the amplitude response will be generally flat, and the group delay curve will drop off at the frequency extremes (near 0 and 5.38 MHz) because of the channel filter's group delay. Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 30 Linear Quad Display Screen Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 31 DTVision Non-Linear - Optional This section contains information regarding the DTVision Screens. These screens are optional diagnostic screens. They are not necessary for the operation of the Axciter. However, they greatly enhance the experience. These graphs provide the same type of views as an EFA. All of the Nonlinear screens have the following reference values displayed EVM The error vector magnitude (EVM) value indicates quality of the digital modulation. EVM is defined as the RMS error at the sampling instants divided by the RMS of the ideal symbols. The error is expressed as a percentage. As signal quality increases, this value decreases. S/N The transmitted signal quality is also expressed as an in-band signal to noise ratio, expressed in dB. As signal quality increases, this value will increase (logarithmically). DAC Headroom ever negative, then there is clipping in the IF modulator, nonlinear equalizer, and/or the DAC. If this happens, lower the unity gain reference point for the nonlinear equalizer. EVM The error vector magnitude (EVM) value indicates quality of the digital modulation. EVM is defined as the RMS error at the sampling instants divided by the RMS of the ideal symbols. The error is expressed as a percentage. As signal quality increases, this value decreases. S/N The transmitted signal quality is also expressed as an in-band signal to noise ratio, expressed in dB. As signal quality increases, this value will increase (logarithmically). Digital to Analog Converter (DAC) Headroom This parameter shows the amplitude (in dB) of the equalized IF signal with respect to the maximum output from the digital to analog converter (DAC). A positive value indicates normal operation and no clipping. If this value is ever negative, then there is clipping occurring in the IF modulator, nonlinear equalizer, and/or the DAC. If this happens, lower the unity gain reference point for the nonlinear equalizer. Peak to Average Ratio This value shows the peak to average ratio of the transmitted signal. This value is typically 6 to 8 dB for a perfect signal. A value significantly lower will indicate peak compression. A small amount of peak compression is normal. Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 32 This parameter shows the amplitude (in dB) of the equalized IF signal with respect to the maximum output from the digital to analog converter (DAC). A positive value indicates normal operation and no clipping. DTVision Non-Linear Home/Spectrum Screen Digital ATSC Exciter-Modulator System Chapter 2, Installation and Operating Instructions Axcera Axciter, Rev. 0 33 DTVision Peak to Average Screen Peak to Average Ratio Display: This screen shows the peak to average ratio in a statistical fashion. The red trace shows the ideal signal's peak to average ratio statistics, and the yellow trace shows the statistics of the transmitter's output. The curves show the cumulative distribution function of the peak to average ratio's probability density. The horizontal scale shows the peak to average ratio measured in decibels. The vertical scale shows the percentage of the time that the peak to average ratio exceeds the value on the horizontal scale. The vertical scale is logarithmic. When the transmitter is clipping signal peaks, the low probability, high peak to average portion of the (yellow) curve for the transmitter's output will appear to the right of the (red) curve indicating the ideal signal.

System Overview Each Innovator HX Series UHF transmitter system consists of an Exciter/Driver System Control Cabinet and one or more RF Power Amplifier (PA) Cabinets each of which has a maximum power output of 5 kW DTV. The Exciter/Driver System Control Cabinet contains a computer with a touch screen, keyboard and mouse and a UPS power supply. Also part of the exciter/driver cabinet are an HX Series Driver/Amplifier Assembly and an Axciter Modulator. An external Dual Peak Detector Board generates a forward and a reflected power sample for metering purposes in the driver/amplifier assembly. A Serial LoopThru board is part of the cabinet assembly and provides system serial interface connection to both the Axciter and the Driver/Amplifier Assembly. A relay is also part of the cabinet assembly and is used to switch the prefiler and postfilter samples to the Axciter Modulator for use by the Adaptive Digital Equalization. NOTE: Refer to the separate Axciter Modulator Instruction Manual for more detailed information on the Axciter Modulator Tray and the Upconverter and Downconverter Modul…
