RINxOMA is a metric used to evaluate the ratio of relative intensity noise (RIN) to optical modulation amplitude (OMA) of an optical module, which reflects the noise performance and signal quality of the optical module. This paper describes a method for RINxOMA testing using the MP2110A instrument and analyses the advantages and application scenarios of the method.

Keithley 2400 Digital Source Meter is an advanced multifunctional power supply and measurement instrument, which is widely used in current measurement in various fields. Switch on the instrument and connect Keithley 2400 Digital SourceMeter to a computer, set the following parameters through the instrument panel or remote control software: measurement mode, current range, sampling rate, trigger mode, etc.

Keithley 2400 Digital Source Meter is an advanced multifunctional power supply and measurement instrument which is widely used in current measurement in various fields. This article describes how to use Keithley 2400 Digital SourceMeter to measure current, including setting measurement parameters, connecting circuits and analysing results. Before measuring current, you need to set the measurement parameters. Turn on the instrument power and connect Keithley 2400 Digital SourceMeter to the computer, set the following parameters through the instrument panel or remote control software: measurement mode, current range, sampling rate, trigger mode and so on. Measurement mode can choose continuous measurement mode or single measurement mode, according to the actual demand. The current range is selected according to the estimated value of the measured current to ensure that the current does not exceed the rated range of Keithley 2400.

Yokogawa AQ6373E Spectrum Analysers - The same high performance level and improved operability features to meet a wide range of spectral measurement needs in R&D and production environments. Yokogawa has designed the Yokogawa AQ6373E and Yokogawa AQ6374E to meet the growing demand for testing new optical devices and components in the visible to near-infrared wavelength bands for medical, biological and materials processing applications.

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 Wideband Pulse Radar Test Solution combines commercial off-the-shelf COTS modular hardware and software from Keysight Technologies, KJ Microwave, and Virginia Diodes to provide a flexible, multi-channel test bench for radar waveform generation and analysis.
Segmented memory acquisition in the digitiser uses a circular acquisition buffer with a minimum inter-segment dead time of 300 ns. This allows, for example, the capture of up to 64 million repetitive radar signals at relatively large repetition intervals.

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.
