What is a signal analyzer?

A signal analyzer is a device used to test and measure electronic signals. Types of signals can vary, including voltage, current, and radiofrequency. Signal analyzers vary in their capabilities and features, depending on the application. There are many types of signal analyzers, but the most common type is an oscilloscope. Other types include spectrum analyzers, network analyzers, and signal generators.

Vector Signal Analyzer vs Spectrum Analyzer – What's the difference?

A signal analyzer analyzes signals that have already been generated, whereas a spectrum analyzer is used to discover frequencies or actually generate frequencies itself. A spectrum analyzer performs real-time spectrum analysis and measures instantaneous power or peak power, voltage, or current, depending on the type of signal being analyzed. It is also often used to monitor electromagnetic interference in circuits and devices. On the other hand, a signal analyzer can only measure signals that are already present; it cannot be used to discover or analyze frequencies. Its purpose is to help the user identify electronic circuit problems and understand how the circuit is performing.

Signal Analyzer vs Oscilloscope – What's the difference?

The main difference between a signal analyzer and an oscilloscope is that a signal analyzer analyzes the voltage of a signal over a specific period of time. In contrast, an oscilloscope extracts the timing information of a signal. An oscilloscope is a type of signal analyzer used to measure voltage signals over time. It has various features, including analog and digital functions, advanced triggering capabilities, and connectivity options. It is used to analyze signals from many different sources, such as time-domain signals, frequencies from radiofrequencies, or extremely low-frequency sources. A signal analyzer is used to analyze signals that have already been generated. A signal analyzer is often used to monitor electromagnetic interference in circuits and devices, whereas an oscilloscope can only measure signals that are already present.

Signal Analyzer vs. Vector Network Analyzer – What's the difference?

A network analyzer is used to test the performance of wired or wireless networks by examining both transmitted and received signals. Unlike a signal analyzer, it performs advanced analysis of both transmitted and received signals. It is different from a signal analyzer because it performs a live, real-time, analysis of signals on the device under test. In contrast, a signal analyzer only analyzes data after the signal has been created. A network analyzer can also perform analysis and detect problems that prevent a signal from reaching its destination. For example, it can detect issues with cabling, connectors, or faulty equipment. It can also help resolve RF spectrum and Wi-Fi issues, such as interference and signal loss. A signal analyzer is used by engineers to identify problems in electronic circuits and to understand how a circuit is behaving; for example, monitoring electromagnetic interference between multiple signals or devices. This makes it useful for testing and debugging circuits that use radio signals or other powerful sources of potential interference.

How to measure antenna impedance with a signal analyzer?

An antenna's impedance refers to the way it responds to signals from specific frequencies. If you want to know what sort of wireless signal a device is sending, you should evaluate the antenna's impedance with a spectrum analyzer. The device would help you determine whether or not your antenna is being affected by noise, which can negatively impact performance. To measure your antenna's impedance, you can attach a spectrum analyzer to the end of the coaxial cable connected to the back of your antenna. The device will then calculate the impedance being transmitted once it goes through your coaxial cable.

How to measure phase noise with a signal analyzer?

Phase noise is a type of signal that often disrupts or interferes with wireless communication. It is a problem for devices that operate in the wireless frequency spectrum. If phase noise is common across specific frequencies, it can drown out other signals. There are many different types of phase noise, and each one can affect your wireless technology differently. A signal analyzer measures the phase noise across different frequencies. The device will help you to determine whether your intended wireless communication needs some sort of interference protection. To measure your device's phase noise with a signal analyzer, you can attach the device to the input of your receiver. This will allow the signal analyzer to calculate how much phase noise is being sent through your wireless communication devices.

How to measure return loss with a signal analyzer?

The return loss is the measurement of how much signal is reflected or wasted at a particular point. It is a measurement of how much energy is being lost in transmission. You can measure return loss with a spectrum analyzer which may enable you to improve the power and efficiency of your wireless connection. If the return loss is too high, it could indicate power-management issues within your system. A signal analyzer can help you determine whether the return loss is too high, and help you find any hardware issues needing to be resolved. The device can notify you when your power-management settings fall below requirements for successful wireless communication. To test a device’s return loss with a signal analyzer, plug the spectrum analyzer into the end of a coaxial cable connected to your intended transmitter. The device will determine how much signal is lost after it goes through the cable and exits to reach its intended recipient.

常见问题

什么是信号分析仪？

信号分析仪是用于测试和测量电子信号的设备。信号的类型可能会有所不同，包括电压、电流和射频。信号分析仪的功能和特性因应用而异。信号分析仪有多种类型，但最常见的类型是示波器。其他类型包括频谱分析仪、网络分析仪和信号发生器。

示波器是设计电子系统时使用的一种设备，它允许将信号视为波形。频谱分析仪测量特定时间段内信号的幅度和频率。网络分析仪在无法访问其设计细节的情况下分析电路；当创建电路和测试电路之间存在延迟时，这会很有帮助。信号发生器生成信号，然后供其他设备使用。

信号分析仪有多种用途，具体取决于设备类型和可用功能。一些标准功能包括：
生成和分析信号
放大和分析大信号
显示不同类型的波形
显示信号的整个频率范围，包括不同频率和噪声水平的视觉表示

矢量信号分析仪与频谱分析仪的区别是什么？

信号分析仪分析已经生成的信号，而频谱分析仪用于发现频率或实际生成频率本身。

频谱分析仪执行实时频谱分析，并根据所分析的信号类型测量瞬时功率或峰值功率、电压或电流。它还经常用于监测电路和设备中的电磁干扰。

另一方面，信号分析仪只能测量已经存在的信号；它不能用于发现或分析频率。其目的是帮助用户识别电子电路问题并了解电路的性能。

信号分析仪与示波器的区别是什么？

信号分析仪和示波器之间的主要区别在于，信号分析仪分析特定时间段内信号的电压。相反，示波器提取信号的时间信息。

示波器是一种信号分析仪，用于测量随时间变化的电压信号。它具有各种功能，包括模拟和数字功能、高级触发功能和连接选项。它用于分析来自许多不同来源的信号，例如时域信号、射频频率或极低频源。

信号分析仪用于分析已经生成的信号。信号分析仪通常用于监测电路和设备中的电磁干扰，而示波器只能测量已经存在的信号。

阅读我们的示波器基础指南，了解有关示波器及其使用的更多信息。如需查看我们在售示波器的完整列表，请访问我们的产品列表页面.

信号分析仪与矢量网络分析仪的区别是什么？

网络分析仪通过检查发送和接收的信号来测试有线或无线网络的性能。与信号分析仪不同，它对发送和接收的信号进行高级分析。它不同于信号分析仪，因为它对被测设备上的信号进行实时分析。相反，信号分析仪仅在创建信号后分析数据。

网络分析仪还可以执行分析并检测阻碍信号到达目的地的问题。例如，它可以检测电缆、连接器或故障设备的问题。它还可以帮助解决射频频谱和Wi-Fi问题，如干扰和信号丢失。

信号分析仪被工程师用来识别电子电路中的问题，了解电路的行为方式，例如，监测多个信号或设备之间的电磁干扰。这使得它对于测试和调试使用无线电信号或其他强大的潜在干扰源的电路非常有用。

如何用信号分析仪测量天线阻抗？

天线的阻抗指的是它对特定频率信号的响应方式。如果你想知道设备发送的是哪种无线信号，你应该用频谱分析仪评估天线的阻抗。该设备将帮助您确定天线是否受到噪声的影响，噪声会对性能产生负面影响。

要测量天线的阻抗，可以在连接到天线背面的同轴电缆的一端连接频谱分析仪。一旦设备通过同轴电缆，它将计算传输的阻抗。

如何用信号分析仪测量相位噪声？

相位噪声是一种经常干扰无线通信的信号。对于在无线频谱中工作的设备来说，这是一个问题。如果相位噪声在特定频率上很常见，它可能会淹没其他信号。

相位噪声有许多不同的类型，每种类型都会对您的无线技术产生不同的影响。信号分析仪测量不同频率的相位噪声。该设备将帮助您确定预期的无线通信是否需要某种干扰保护。

要使用信号分析仪测量设备的相位噪声，可以将设备连接到接收机的输入端。这将使信号分析仪能够计算出有多少相位噪声是通过你的无线通信设备发送的。

如何用信号分析仪测量回波损耗？

回波损耗是测量在特定点反射或浪费多少信号。这是一个衡量在传输过程中损失了多少能量的指标。您可以使用频谱分析仪测量回波损耗，从而提高无线连接的功率和效率。

如果回波损耗过高，则可能表明系统中存在电源管理问题。信号分析仪可以帮助您确定回波损耗是否过高，并帮助您找到需要解决的任何硬件问题。当您的电源管理设置低于成功无线通信的要求时，设备会通知您。

要使用信号分析仪测试设备的回波损耗，请将频谱分析仪插入连接到预期发射机的同轴电缆的一端。该设备将确定在信号通过电缆并流出到达预定接收者后，有多少信号被丢失。

有关如何使用频谱分析仪测量回波损耗的其他信息，请查看“功能资源”，以获取基本频谱分析仪的技术概述以及如何测量天线回波损耗的示例。
