A signal is what is produced by a signal generator when testing electronic equipment. The signal can be a basic sine wave, a pulse or a modulation signal. The signals that are produced are used to test, troubleshoot and design electronic equipment.

What is a signal generator, and what is it used for?

A signal generator is an electronic testing instrument that creates repeating or non-repeating electric waves of different shapes and amplitudes. A signal generator gives clear and concise feedback about the product's performance. Signal generators are used in many different fields, but they are most important in the fields of electronics and radio communications. Engineers use this tool to test their own electronic equipment, as well as to design new equipment for other companies.

Why should I buy a Keysight signal generator?

A Keysight signal generator is a valuable addition to any test system because it provides the accuracy, performance, and insights you need to streamline your design or repair process. We are known for producing quality instruments in the industry, be it in digital RF processing, satellite communications, radar sensing and tracking, wireless communications or wireless & mobile test equipment. We want you to find the signal source that's right for your needs. We have a variety of signal generators for you to choose from. They range in frequency, but they all perform well and are easy-to-use whether it's your first time using one or not.

When would I need a vector signal generator?

The vector signal generator is a type of signal generator that generates radio frequency signals with complex modulation formats. When a radio signal modulates, it changes either the amplitude or the frequency of the carrier wave.

Signal generator vs waveform generator

There are two types of machines for creating signals. One is called a signal generator and the other is called a waveform generator. A signal generator is an electronic test instrument that generates either repeating or non-repeating waveforms. A waveform generator creates a wave. It is a type of signal generator that creates very sophisticated waveforms that can be specified by the user. These waveforms can be almost any shape and can be entered in a variety of ways.

Signal generator vs function generator

The function generator is a type of signal generator that is used to generate simple repetitive waveforms. Typically this type of signal generator will produce waveforms such as sine waves, sawtooth waveforms, square and triangular waveforms. Please refer to Basic Oscilloscope Fundamentals for more information on waveforms. Digital signal processing techniques may be used to generate the waveforms digitally, then convert them from digital into analog format. This is especially true when you only require the waveforms to be at lower frequencies. However, higher frequency versions can be obtained.

Signal generator vs oscilloscope

An oscilloscope “scopes out” or monitors a given signal applied on its input. It displays the signal as voltage vs time. A signal generator can be used to generate a signal with specific characteristics to test devices. A signal generator and an oscilloscope together form a tool that could, for example, diagnose an amplifier. The oscilloscope could then perform basic math on both the input and output to calculate, for example, changes in gain or linearity over a given range of parameters. Keysight offers two standards of used equipment: Keysight Premium Used and Keysight Used. Keysight Premium Used instruments are fully refurbished to factory new condition, with the same warranty as new ones. Keysight Used equipment is tested and working with the cosmetic appearance described in each product listing.

What are EXG signal generators?

The abbreviation "EXG" stands for "exciter." An exciter is a signal generator that creates a signal and then applies it to an RF power amplifier to generate the final transmitted radiofrequency. The exciter is employed in digital systems as part of waveform generation. EXG signal generators provide the signals you will need for basic parameter testing of components. It is a tool used to test equipment such as computers which allows users to see how the equipment will work in a variety of situations. The EXG signal generator allows you to customize microwave components, such as filters and amplifiers, with additional features including full step attenuation. It also maximizes test margins on the production line with leading Adjacent Channel Power Ratio (ACPR).

常见问题

什么是信号？

信号发生器测试电子仪器时会发出信号，信号可以是基本正弦波、脉冲或调制信号。产生的信号用于测试、故障排除和设计电子仪器。

信号发生器是什么，有什么用？

信号发生器是一种电子测试仪器，可以产生不同形状和振幅的重复或非重复电波。信号发生器能够清晰、简洁、直接地反馈一个仪器性能。信号发生器能用于许多不同的领域，但在电子和无线电通信领域最为重要。工程师会使用信号发生器来测试他们自己的电子仪器，以及设计新仪器。

signal_generator_cat_Figure.1 N5166B CXG RF Vector Signal Generator, 9 kHz to 6 GHz — 图1. N5166B CXG 射频矢量信号发生器，9 kHz 至 6 GHz

例如，信号发生器常连接在示波器上，生成可用于测试电信号的正弦波（平滑曲线）。单击此处了解更多有关示波器的信息。

其他类型的信号发生器有：

任意波形发生器
音频信号发生器
函数发生器
脉冲发生器
射频信号发生器
矢量信号发生器

不同类型的发生器发出不同种类的信号。例如，有些可以发出射频和音频信号，有些可以生成波形或只是脉冲信号。

想要查看是德科技的信号发生器的全部产品列表，请单击此处访问我们的产品列表页面。

我为什么选择是德科技的信号发生器？

不管是进行什么测试，是德科技的信号发生器都可以凭其优秀的准确性，性能和洞察力让您的测试系统变得更加完美，帮助优化您的设计或维修流程。无论是在数字射频处理、卫星通信、雷达传感和跟踪、无线通信还是无线和移动测试仪器领域，我们的仪器都以其优秀的质量闻名于行业内。

为了您能找到最符合需求的信号种类。我们有各种类型、各种频段的信号发生器供您选择。产品种类虽多，但不管是哪一款产品的性能都同样优秀，并且便于操作，哪怕是第一次使用，也可以很快上手。

什么情况会需要用到矢量信号发生器？

矢量信号发生器能够发出一种具有复杂调制格式的射频信号。当无线电信号调制时，矢量信号发生器能够改变载波的振幅或频率。

signal_generator_cat_Figure.2 Keysight N5166B Vector Signal Generator — 图2. 是德科技 N5166B 矢量信号发生器

矢量信号发生器用于测试不同的现代数据通信系统。常用于检查Wi-Fi、4G/5G，以及解决其他使用高级波形的连接问题。

信号发生器和波形发生器，有何异同？

有两种不同的能够发出信号的机器，一种叫做信号发生器，另一种叫做波形发生器。信号发生器是一种既能生成重复波形也能生成非重复波形的电子测试仪器。

signal_generator_cat_Figure.4 Keysight PSG Signal Generator — 图4. 是德科技 PSG 信号发生器

波形发生器则能够生成由操作者指定的复杂波形，几乎任何形状的波形都可以生成，且可以以多种方式输入。

signal_generator_cat_Figure.5 EDU33211A Waveform Generator, 20 MHz, 1 Channel .png — 图5. EDU33211A 波形发生器, 20 MHz, 1 通道

信号发生器和函数发生器，有何异同？

函数发生器是一种用来发出简单、重复波形的信号发生器。这种信号发生器一般用来生成如正弦波、锯齿波、方波和三角波等波形。单击此处查看示波器基本原理，了解有关波形的更多信息。

数字信号处理技术以数字方式生成波形，然后将波从数字信号转为模拟信号。当你仅需要一个较低频率的波形时，这将尤其有用。当然，较高频率的波形也适用此方法。

信号发生器和示波器如何一起使用？

示波器可以找到并监视施加在其输入端的给定信号，并把这个信号以函数（电压和时间）的形式展示出来。而信号发生器可以发出具有特定特性的信号，以测试设备。

想要查看我们的示波器的全部产品列表，请单击此处访问我们的产品列表页面。

signal_generator_cat_Figure.6 Oscilloscope displaying voltage vs time — 图6. 示波器所展示的函数（电压和时间）图像

你可以同时使用信号发生器和示波器来实现一些新的功能。比如，诊断放大器。示波器可对输入和输出的信号进行基本运算，如计算给定参数范围内的增益或线性变化。

是德科技有两种不同的二手仪器：原厂翻新仪器和原厂二手仪器。前者经过了返厂全面翻新，有近乎新产品的质量和与新产品相同的质保期。原厂二手仪器经过测试确定可以正常使用，每一台仪器在产品列表中的商品图都是该件仪器的原图。

什么是EXG信号发生器？

“EXG”是单词“exciter”的缩写，意为“激振器”。激励器是信号发生器的一种，能够发出一个信号，然后将其施加在射频功率放大器上，最后将射频发射出去。在数字系统中，激振器常作为波形产生阶段的一环。

EXG信号发生器发出的信号可用来测试组件的基本参数。使用EXG信号发生器测试计算器之类的仪器，可以了解仪器在各种情况下的工作情况。

EXG信号发生器可以让您自己定制微波组件，如滤波器和放大器，还有包括全步衰减等其他功能。它还可以利用相当高的相邻通道功率比（ACPR）在生产线上把测试利润最大化。
