Abstract: 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.

Abstract: 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.

Abstract: A pattern sequence and state transition trigger generator provides a trigger when a specified transition from one pattern/state to another pattern/state occurs in a set of input signals. Decoders detect each specified pattern/state from the set of input signals to produce a prior value and a current value representing the transition. The prior value is slightly delayed and combined with the current value to produce an overlap when the specified transition occurs, which in turn generates the trigger.

Abstract: Position Lock Trigger apparatus employs oscilloscope circuitry and accompanying control software to provide to a user the capability to trigger an oscilloscope on a selected bit position in a received serial bit stream having a fixed pattern length, using either a synthesized, recovered, or external clock source. The selected trigger position can be moved forward and backward along the serial bit stream by one or more serial bit positions at a time in order to examine the entirety of the fixed pattern length serial bit stream, with or without regard to the actual bit sequences occurring in the serial stream.

Abstract: System and apparatus enabling the use of a single cable to communicate triggering information between each of a plurality of signal acquisition devices and, illustratively, an external trigger control unit. A combined trigger signal is produced only when each trigger condition of each signal acquisition device is true. Thus, all of the signal acquisition devices will be triggered substantially simultaneously.

Abstract: An advanced trigger circuit includes two trigger decoders, each triggering on one of respective pluralities of continuous-time trigger events. In one embodiment, a programmable timer begins timing in response to an output signal of the first trigger decoder and generates an end-of-time signal at the expiration of its time period. A reset circuit resets the first trigger decoder if the second selected continuous-time trigger event failed to occur before the end-of-time signal was generated. In another embodiment, a reset decoder generates a reset signal in response to an occurrence of a selected continuous-time trigger event. The reset circuit is responsive to the reset signal for resetting the first trigger decoder if the second selected continuous-time trigger event failed to occur before the reset signal was generated. In other embodiments, the advanced trigger circuit triggers on a serial lane skew violation or on a beacon width violation.

The compounds of the invention and their pharmaceutically acceptable salts find particular use as photosensitizing agents in the photochemical internalization of molecules and in photodynamic therapy.

Abstract: A combined analog and DSP trigger system for a digital storage oscilloscope (DSO) enables the DSO to real-time trigger on events in an input analog signal based on traditional trigger events in the input analog signal and/or predetermined anomalous events detected in digitized samples of the input analog signal. A processor receives the digitized samples at the input of an acquisition memory to detect the anomalous events and provides an event detect signal to the trigger system. Predetermined amounts of the digitized samples around the events are acquired in an acquisition memory for further processing and display.
