    摘要： A signal acquisition system has a signal acquisition probe having probe tip circuitry coupled to a resistive center conductor signal cable. The resistive center conductor signal cable is coupled to a compensation system in a signal processing instrument via an input node and input circuitry in the signal processing instrument. The signal acquisition probe and the signal processing instrument have mismatched time constants at the input node with the compensation system having an input amplifier with feedback loop circuitry and a compensation digital filter providing pole-zero pairs for maintaining flatness over the signal acquisition system frequency bandwidth.

    摘要： Disclosed is a test and measurement instrument that includes a signal input structured to receive a modulated radio frequency (RF) signal under test and a demodulator structured to extract a digital signal from the received modulated RF signal. The extracted digital signal has a measurable parameter. The instrument also includes a display controller structured to display the extracted demodulated signal at one of at least two different intensities based on the measured parameter of the digital signal. In other embodiments the signal need not be an RF signal. Methods of operation are also described.

    摘要： A method of drawing a waveform image in a no dead time acquisition system, where consecutive drawing frames overlap, uses a master/slave relationship between two fast rasterizers. The master rasterizer draws a first display frame in response to a first trigger event in a trigger signal derived from an input signal. The slave rasterizer draws a second display frame in response to a subsequent trigger event in the trigger signal. The portion of the second display frame that duplicates data contained in the first display frame is either (a) suppressed when the first and second display frames are combined to form the waveform image or (b) displayed in a different shade/color. Alternatively the first display frame may be compressed by 50% to form a first portion of the waveform image and the non-duplicative portion of the second display frame is compressed by 50% to form a second portion of the waveform image, the first and second portions being drawn contiguously when the first and second display frames are combined to form the waveform image.
