示波器是一种测试仪器，用于捕获和显示电信号随时间变化的波形图。例如，它可以在其显示屏上绘制电压（y轴）与时间（x轴）的图形。
示波器是设计和测试电子设备的强大工具。它们在判断系统设备组件是否正常工作以及哪些组件发生故障方面起着非常重要的作用。它们还可以帮助您确定新设计的元器件是否能按预期进行工作。这可以通过分析信号参数如幅度、周期、频率、上升时间、脉冲宽度等来完成。现代数字示波器还可以对波形执行数学运算，例如傅里叶变换从而更快完成分析。
A programmable DC power supply is connected to the device under test through wires connected to a DC power panel. Engineers can set voltage or current levels to power the device for testing. The DC power supply is a programmable DC power supply.
View Full VersionCan. Many AC power sources can produce DC directly, or by superimposing a DC bias on the AC waveform. ,
View Full VersionVector network analyzers (VNAs) are test instruments that measure electrical network parameters. They are essential for radio frequency (RF) and microwave component analysis of a wide variety of passive and active devices including filters, antennas and power amplifiers. Network analyzers are ideal for transmission, reflection and impedance measurements as well as s-parameter measurements during design and production. Network analyzers...
