Yokogawa Electric Test & Measurement has announced the June 2023 release of the Yokogawa AQ6370E spectrum analyser. An upgrade to the popular Yokogawa AQ6370D, the new model is equipped with enhanced performance and usability features. Equally suitable for use in industry, universities and research institutes, this Yokogawa AQ6370E can be used to characterise a wide range of components, including lasers, optical transceivers and optical amplifiers for optical communications.

There is no definite answer to this question because different brands of spectrum analysers may suit different application scenarios and needs. You can choose the most suitable brand according to your budget, measurement target, wavelength range, accuracy requirement and other factors. I can give you some suggestions for reference, but the final decision is still up to you.

The M8195A Arbitrary Waveform Generator is a high-performance signal source that can generate arbitrary waveforms with a sampling rate of up to 65 GSa/s and an analogue bandwidth of 25 GHz. It can be used to simulate a variety of complex signals, such as radar signals, optical communication signals, digital RF signals and so on. In this paper, we will introduce the methods and precautions for simulating radar signals using the M8195A Arbitrary Waveform Generator.

The Anritsu MT1000A is a full-featured network tester that performs a wide range of tests on communication networks, such as Ethernet, CPRI, OTDR, OTN, SONET/SDH, and PTP.It is a compact, battery-powered, and easy-to-use unit that can support speeds from 1.5 Mbps to 100 Gbps. It has a modular design that allows you to install different modules and options according to your needs. It also features a simple and intuitive graphical user interface, a large 9-inch screen display, and multiple connectivity options. It can generate reports in PDF, CSV and XML formats for documenting test results. It is a versatile and powerful tool for network installation and maintenance.

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.
