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.

We should know that optical network is a network technology that uses optical signals to transmit information, and it is one of the important infrastructures of the modern information society. With the development of Internet technology, human demand for network bandwidth continues to grow rapidly and explosively, optical network technology is also facing the challenge of improving transmission rate, capacity and quality. So what are the advantages of optical networks? Simply put, it is fast, big and good.

Optical communication is a technology that uses optical signals to transmit information, and it is one of the key infrastructures of the modern information society. The development of optical communication has gone through several stages, from the initial optical fibre to the current optical network, which has continuously improved the transmission rate, capacity and quality. Optical communication is a technology that lights up the future and will bring more convenience, innovation and value to human society.
