摘要： A digital trigger circuit has a plurality of data samples extracted from an input electrical signal for each sample clock cycle. The plurality of data samples are compared in parallel with a high threshold level and a low threshold level which provides hysteresis for noise rejection. Also the plurality of data samples are used to determine sub-sample trigger positioning. The comparison outputs (A H , A L ) are input to a digital trigger logic circuit (26) for identifying a selected trigger event and generating a trigger for the acquisition of data from the input electrical signal for analysis and display. The digital trigger logic provides edge event triggering, pulse width triggering and transition time triggering, among others.

摘要： Outputs of a linear RF detector and a logarithmic RF detector are multiplexed individually to a single digitizer or simultaneously to a respective digitizers. A process generates a composite waveform from the resulting digitized data, either at a later time in the former case or in real-time in the latter case. To achieve simultaneous routing, several routing relays are arranged in a specialized configuration between the outputs of the RF detectors and the inputs of the digitizers.

摘要： An oscilloscope apparatus for scaling and displaying persistence data using interpolation. The oscilloscope apparatus acquires a waveform and accumulates persistence data of the acquired waveform in a results buffer. The size of the persistence data is selectable by the user. A processor scales the persistence data using an interpolation algorithm to the size of a buffer in the display. The user may select a region of interest within the persistence data for scaling and display. In this manner, the persistence data can be zoomed in/out and centered on the display. The interpolation algorithm may be automatically selected or set by the user from standard, bi-linear, bi-cubic, or super-sampling algorithms.
