摘要： A test and measurement apparatus, system, and method for synchronizing an acquisition or triggering system to a specific burst of interest. The subject apparatus and method triggers on varying energy content of a signal qualified by time in the presence of high-frequency input signal bursts, by using an adjustable pulse width envelope detector, disposed in the signal path of the trigger circuitry, as a digital rectifier or to otherwise process and extract an envelope signal. An RF envelope probe having an analog envelope detector among other suitable components is disclosed. A method is implemented for isolating an interval of interest in a signal under test. An envelope detector circuit produces an envelope signal from the signal. Trigger circuitry receives the envelope signal from the envelope detector, and isolates the interval of interesting in the signal under test using the envelope signal.

摘要： A method for improving performance and flexibility of serial data analysis in test instruments, is independent of data bit rate, encoding scheme or communication protocol embodied in the serial data. The serial data is input to a transmitter section, where it is demultiplexed into a plurality of multi-bit lanes, such as 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 at a data rate that is optimal for the receiver section. In the receiver section the N lanes are deserialized, decoded and input to a word recognizer to generate a trigger event signal.

摘要： A dF/dT trigger system and method includes instantaneously triggering on a frequency deviation of a data signal, which can be associated with an SSC signal. After receiving a signal at an input terminal of a test and measurement instrument, the signal is low-pass filtered and transmitted to trigger circuitry. When a frequency deviation rate in the filtered signal exceeds or crosses one or more thresholds, a trigger event is produced. Also disclosed is a test and measurement instrument including an input terminal to receive the signal, input circuitry to receive and process the signal, and dF/dT trigger circuitry configured to receive the signal and produce a trigger event when a frequency deviation in the signal exceeds or crosses one or more thresholds.

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.
