摘要： In a method and an optical switch by which a signal light is accurately switched even if a polarization state of a signal light inputted has a fluctuation, power of an output light of a polarizer which receives a signal light extracted from an output light of a nonlinear optical medium is monitored and a polarization state of an input signal light to the nonlinear optical medium is controlled so that the power becomes minimum (or maximum). The polarization state of the input signal light is monitored, a calculation of performing a predetermined conversion is executed to the polarization state of the input signal light, and a calculated polarization state is recorded (or recorded without conversion). A polarization state of a control light with respect to the input signal light is monitored and the polarization state of the control light is controlled so as to coincide with the polarization state of the input signal light recorded.

摘要： A trigger architecture (105) includes a plurality of parallel analog-to-digital converters (ADCs) (106,107,108,109,110) operative to garner data samples (116,117,118,119,120) in parallel from an input signal (113) at different times in a clock signal period. The trigger architecture also includes a logic block (111) comprising a plurality of digital comparators (301,302,303,304,305), which are adapted to compare each of the data samples to one or more threshold values in parallel. A measurement system (100) including the trigger architecture (105) is described.

摘要： A method and apparatus for acquiring a signal 110 employing a coherent timebase are provided. The method comprises the steps of defining a pattern length count 360 of a repetitive pattern in a signal 110 to be acquired, defining a number of samples per unit interval, and providing data strobes 225 synchronous to a coherent timebase. An arbitrary one of the data strobes is designated as a timing for a potential trigger 120. A number of subsequent data strobes is counted 360 in accordance with the pattern length count times the samples per unit interval and a portion of the signal corresponding to the pattern length count times the samples per unit interval is acquired beginning at a point in the signal defined by the designated arbitrary data strobe. Thereafter one or more additional portions of the signal 110 are acquired 435 corresponding to the pattern length count times the samples per unit interval at a point 150 in the signal 110 defined by when the number of subsequent data strobes reaches the pattern length count times the samples per unit interval.

摘要： A method and apparatus for digitally sampling electrical waveforms. A sampling circuit (22) for sampling an electrical signal, a digitizing circuit (30a-30d) for digitizing the samples produced by the sampling circuit and an acquisition memory (36) for storing the samples are employed, the acquisition memory being partitioned into a plurality of frames. Each frame is triggered to store samples associated with a respective triggering event. After substantially all of the frames have been triggered, the contents of the acquisition memory are retrieved from the acquisition memory, filtered in an equalization filter and stored in a waveform memory (42) for ultimate display as an ET record under software control. A plurality of digitizing circuits associated with respective inputs of a multi-channel digital sampling oscilloscope are interleaved to increase the sampling rate.
