摘要： A frequency spectrum measurement apparatus sweeps a desired frequency range using multiple scan lines. A controller provides a non-contiguous sequence of input values to a frequency synthesizer operating as a local oscillator for generating a non-contiguous frequency output signal over the desired frequency range with each value offsetting a current frequency output signal from a previous frequency output signal. A mixer receives an input signal and the variable frequency synthesizer signal for generating an intermediate frequency signal that is filtered through a bandpass filter. The power of the intermediate frequency signal output of the bandpass filter is measured and displayed. The frequency spectrum measurement apparatus is usable in measuring out of channel emissions of a terrestrial RF broadcast digital television signal.

摘要： A measurement acquisition and display system generates graphical displays of Cumulative Distribution Function (CDF) peak-to-average power ratio measurements of a digitally modulated RF signal and an ideal digitally modulated RF signal, such as an 8-VSB digital television signal. A variable target operating point or planning factor value is enterable into the system that defines an operating point on the ideal CDF of peak-to-average power ratio display. The corresponding operating point on the RF signal CDF of peak-to-average power ratio display is determined and numerically displayed along with a numerical display of the difference between the ideal and real operating points. Alarm limit variables may be set for generating an alarm signal when the RF signal peak-to-average power ratio exceeds the alarm limits. The measurement acquisition and display system further generates a graphical display of channel frequency spectrum of the digitally modulated RF signal.

摘要： A measurement receiver demodulator has a first processing channel for producing a filtered signal sample output where the signal samples are processed through a transmission system receiver filter and a second processing channel producing an unfiltered signal sample output where the signal samples are not processed through the transmission system receiver filter. The first processing channel down converts digitally modulated IF signal samples and filters the down converted signal samples using a combined transmission system receiver filter and front end hardware compensation filter. A synchronizer produces timing phase and rate offset parameters that are applied to a resampling filter to synchronize the filtered signal samples to symbol instances of the symbol modulation. The filtered, time-aligned signal samples are scaled using a derived scaling factor. A pilot offset level, if present, is estimated and removed. The resultant signal samples are processed through an equalizer to produce filtered, time-aligned, scaled equalized signal samples that are output as filtered signal samples. The second processing channel receives the down converted signal samples and uses compensation and equalization filter coefficients, timing parameters, and the scaling from the first processing channel in compensation, resampling and equalization filters and a scaler to produce compensated, time-aligned, scaled equalized signal samples that are output as unfiltered signal samples.
