    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 of the signal acquisition probe 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 providing pole-zero pairs for maintaining flatness over the signal acquisition system frequency bandwidth.

    摘要: To increase the percentage of time that an input signal is actively monitored, a digital oscilloscope has an acquisition system (100) that includes an analog-to-digital converter (15), an acquisition memory (40), an acquisition rasterizer (50), and a raster acquisition memory (60). The rasterizer contains circuitry (52) for concurrently rasterizing and combining the results of several acquisitions together and with a stored composite raster image to produce a new composite raster image, while additional acquisition records are being created and stored in the acquisition memory. A display system (220) takes the composite raster images after they contain the results of many acquisitions and overlays these single-bit raster images on a multi-bit raster image that is then decremented to produce a simulated persistence effect. The number of new pixels turned on as a result of each acquisition can be counted (57) during the combining process and used to stop acquisitions, signal the operator, or specially treat that particular acquisition when the number of new pixels created by a particular acquisition exceeds a predetermined value. Acquisition circuitry for multiple channels can be used on one channel to further increase the percentage of time that the signal is monitored.

    摘要: A test and measurement instrument including a splitter configured to split an input signal having a particular bandwidth into a plurality of split signals, each split signal including substantially the entire bandwidth of the input signal; a plurality of harmonic mixers, each harmonic mixer configured to mix an associated split signal of the plurality of split signals with an associated harmonic signal to generate an associated mixed signal; and a plurality of digitizers, each digitizer configured to digitize a mixed signal of an associated harmonic mixer of the plurality of harmonic mixers. A first-order harmonic of at least one harmonic signal associated with the harmonic mixers is different from an effective sample rate of at least one of the digitizers.

    摘要: A signal acquisition system has a signal acquisition probe having probe tip circuitry coupled to a resistive center conductor signal cable with the signal cable coupled to a signal processing instrument via an input node. The input node is coupled to an input current amplifier via input circuitry. The input circuitry provides at least one of resistive and capacitive termination of the resistive center conductor signal cable. The termination of the resistive center conductor signal cable in the signal processing instrument provides a signal acquisition system where the capacitive loading of a device under test at higher frequencies is reduced by reducing the input capacitance of the probe tip circuitry resulting in an increase in the signal acquisition system bandwidth.

    摘要: An eye violation and excess jitter trigger for a digital signal uses a mask within a unit interval of the digital signal, such as a rectangular mask having corners defined by a high threshold, a low threshold, an early clock and a late clock, the early and late clocks being derived from a reference clock. The reference clock may be a recovered clock derived from the digital signal or from high and low threshold comparator outputs, or may be an external clock. For the excess jitter trigger, which is a special case of the eye violation trigger, the high and low thresholds are essentially equal. A status of the digital signal with respect to the mask is determined using the high and low thresholds and the early and late clocks, and a violation signal is output when the status indicates that a portion of the digital signal crossed into the mask. The violation signal may then be used to trigger data acquisition or for other purposes.

    摘要: Serial data is input to a transmitter, where it is demultiplexed into a plurality of multi-bit lanes, e.g. n bits for each of N lanes. The N lanes are then encoded into characters, the encoded N lanes having m bits per lane where m>n. Bit stuffing is used to adjust the data rate and/or to insert qualifiers. The stuffed, encoded N lanes are then multiplexed into N serial lanes, which are output from the transmitter section for input to a receiver section.
    In the receiver section the N lanes are deserialized, decoded and input to a word recognizer to generate a trigger event signal.
