函数发生器提供了一个预置列表，里面列出了它可以生成的波形或码型。 在函数发生器中，用户可以更改频率、幅度和偏移等波形参数，还可添加简单的失真。 任意波形发生器更为复杂，能够仿真真实世界中的信号。 任意波形发生器利用事先存储的数字数据来生成这些波形，这些数字数据描述了信号不断变化的电压。 通常情况下，任意波形发生器产生的是经过编译的定制波形，而不是预置的常见波形。
This article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...
View Full Version串联两个直流电源需要将第一个电源的正极连接到第二个电源的负极， 形成“菊花链”连接，串联电压为两个电源的电压之和。 串联两个直流电源的步骤如下： 请注意，负载的电压应当等于或高于两个电源的电压之和，以防损坏负载或电源。 此外，负载的额定...
View Full VersionIf you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...
