Demonstration of Tektronix's solution for 400G/800G PAM4 measurement PAM4 is a high-speed serial communication technology that can transmit more data under the same bandwidth, and is one of the key technologies to achieve the 400G/800G Ethernet standard. However, PAM4 signals also bring higher testing difficulty, and it is a challenge to measure the quality and performance of PAM4 signals effectively.

Optical module is a device that converts electrical signals into optical signals or optical signals into electrical signals, and it plays an important role in optical communication system. In order to ensure the normal operation of the optical module, we need to test its performance and detect whether it meets the relevant standards and specifications. So, how to test the performance of optical modules? This article will introduce you to some commonly used optical module test methods and test and measurement equipment.

TX and RX are two important concepts in a communication system, representing Transmitter and Receiver respectively. In a communication system, the Transmitter is responsible for converting information signals into electromagnetic waves and sending them out, and the Receiver is responsible for receiving the electromagnetic waves and reducing them to information signals. Therefore, testing the performance of TX and RX is an important step to ensure that the communication system works properly.

PCIe has both a serial communications interface and a storage interface, unlike SAS and SATA, thus enabling additional industry scalability. PCIe supports full-duplex communication based on a point-to-point bus topology between the followers (system/host) and the endpoints (plug-ins). The specifications are developed and maintained by the PCI-SIG, an association of more than 900 companies.

In the field of electronic test and measurement, a signal source is a commonly used instrument that provides a variety of known or preset waveforms, such as sine, square, ramp, and pulse waves, for exciting a circuit or system under test and observing its response. However, sometimes we need to simulate real-world signals that are often irregular, random, complex, or contain multiple frequency components and modulations.

Oscilloscope is a commonly used electronic test instrument, which can display and measure the waveform, amplitude, frequency, phase and other parameters of a signal. However, to use an oscilloscope correctly, not only to understand its functions and operating methods, but also to pay attention to some details and techniques in the actual test. In this article, we will introduce some of the oscilloscope actual test considerations, hope to help electronic engineers.

An eye diagram is a tool used to observe the quality and performance of a high-speed digital signal, which can reflect a lot of information about the signal, such as noise, jitter, inter-code crosstalk, extinction ratio, and signal-to-noise ratio. Eye diagram is a series of digital signals accumulated on the oscilloscope and displayed graphics, it is similar to the shape of an eye, hence the name. The size and clarity of the eye diagram can reflect the quality of the signal. Generally speaking, the larger and clearer the eye diagram is, the better the signal is; the smaller and blurrier the eye diagram is, the worse the signal is.

DCA-X 86100D(86105C) Optical Oscilloscope is a high-performance fibre optic oscilloscope suitable for measuring various fibre optic parameters, such as optical power, optical wavelength, optical attenuation and so on. This article will introduce the use of DCA-X 86100D(86105C) Optical Oscilloscope in detail, including equipment features, operating procedures, precautions, application examples and maintenance.
