摘要： A sampling apparatus for use in high data rate jitter measurement systems based on offset sampling uses a trigger circuit, along with a time-based variable delay, to align a sampling strobe to drive two samplers. An input data signal is split and fed via separate signal paths into the two samplers. One of the samplers is delayed in sampling the input signal or the input is delayed to one of the samplers, such that the two samples of the input signal are offset in time. The jitter present in the SUT can be calculated using the two samples. In addition, when using two strobe circuits, the jitter inherently present in the strobe circuits can be compensated for by offset sampling a reference clock with each main strobe to determine the phase and cycle number of the reference clock at each strobe time.

摘要： Repetitive sampling of a data signal is performed. A clock reference is generated. The clock reference has a known period relationship with the data signal. The clock reference and the data signal are simultaneously sampled. The sampled information from the clock reference is used to determine in what phase of the clock reference sampled values of the data signal occur.

摘要： Error-related information acquired using a bit error ratio detector (BERT) is extrapolated on the basis of prior testing, in which measurements “superior” to those acquired by the BERT are used to provide an initial extrapolation calibration. For example, measures of data dependent jitter acquired by a digital communications analyzer (DCA) may be used to offset the less accurate jitter-related measures by the BERT. As a consequence, the benefits of a DCA and a BERT are combined, while using only the BERT.
摘要翻译：使用误码率检测器（BERT）获取的误差相关信息是基于先前的测试进行外插的，其中使用由BERT获得的测量值“优于”提供初始外推校准。例如，可以使用由数字通信分析器（DCA）获取的依赖于数据的抖动的测量来抵消由BERT产生的不太准确的抖动相关措施。因此，组合DCA和BERT的优点，而仅使用BERT。

摘要： A nonpolarization-dependent method and apparatus for optical sampling of a user optical signal of a known frequency range (e.g., corresponding to 1550 nm wavelength) uses a probe signal in an unsplit form and applies a conversion {e.g., by sum frequency generation (SFG)} operation in a first stage to the probe signal and to a first polarization component of the user optical signal (e.g., ‘s’ component) to produce a first component of an output signal. In a second stage, a second polarization component of the user optical signal (e.g., ‘p’ component) is rotated by 90° to align with the first polarization component and then converted by mixing with the unsplit probe signal to produce a second component of an output signal. The first and second output component signals are both added and measured using a photomultiplier tube (PMT) or an avalanche diode.

摘要： A method and apparatus for sampling optical input signal is presented. The apparatus includes a split waveplate for spatially rotating polarization direction of a first portion (for example half, or 50 percent) of the input signal to a first rotated direction and spatially rotating polarization direction of a second portion (for example the other 50 percent) of the input signal to a second rotated direction orthogonal to the first rotated direction. The apparatus further includes a sum frequency generator, for example a PPLN crystal, aligned to the first rotated direction to sample the input signal. The rotation of the two halves of the input signal is achieved using a split half-waveplate.

摘要： A system and method for asynchronous triggering in a waveform generator comprising a DAC sample clock for generating DAC sample clock signal. The system includes a sequencer clock for generating a sequencer clock signal having a frequency of 1/N of the DAC sample clock. The system also includes an output data generator having I outputs to receive a waveform data stream of samples shifted into the data generator at the rate of the sequencer clock signal. An output multiplexer coupled receives samples from each of the I outputs of the output data generator and outputs the samples as a multiplexed data stream to the DAC. A triggering system receives an asynchronous trigger and splits the signal into an integer multiple M trigger inputs, each trigger input delayed by a DAC sample clock cycle. A shift controller determines a trigger position based on the trigger inputs and shifts a different waveform data stream into the data generator in accordance with the trigger position.
