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.摘要翻译： 串行数据被输入到发射机，在那里它被解复用成多个多比特通道，例如， 每个N通道有n位。 然后将N个车道编码为字符，编码的N个车道每m个位具有m位，其中m> n。 位填充用于调整数据速率和/或插入限定符。 然后将填充的编码的N个通道多路复用到N个串行通道中，这些通道从发送器部分输出以输入到接收器部分。 在接收器部分，N个通道被解串行，解码并输入到字识别器以生成触发事件信号。

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 (210) of a test and measurement instrument, the signal is low-pass filtered (334) and transmitted to trigger circuitry (340). 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.
摘要翻译： dF / dT触发系统和方法包括瞬时触发数据信号的频率偏差，其可以与SSC信号相关联。 在测试和测量仪器的输入端子（210）处接收到信号之后，对该信号进行低通滤波（334）并将其发送到触发电路（340）。 当经滤波的信号中的频率偏差率超过或超过一个或多个阈值时，产生触发事件。 还公开了一种测试和测量仪器，其包括用于接收信号的输入端子，用于接收和处理信号的输入电路以及用于接收信号并在信号中的频率偏差超过时产生触发事件的dF / dT触发电路 或跨越一个或多个阈值。
