What are DC power supplies used for?
386A DC power supply provides a constant bias voltage or current to an electrical device, component, or circuit to ensure that the device under test operates as intended. ,
View Full VersionWhat is IQ modulation?
同相正交调制（IQ 调制）是通信应用中使用的主要调制方案。 它之所以受欢迎，是因为它能高效利用带宽，满足这个数据量急剧增长的世界对带宽越来越迫切的需求。 使用仿真的 IQ 信号进行测试非常重要，因为设计人员在充斥干扰的频谱中总是会面临带宽不足的困境。
例如，设计人员需要测试其设计的极限性能，从而确保它们在真实环境中能够正常运行。 为此，他们必须首先生成一个理想信号来测试设计的理想性能。 因此，他们必须生成一个高品质的已知纯净信号。
他们可以通过调整两个通道之间的增益平衡以及每个通道的幅度偏移来仿真非理想的 IQ 信号。 他们甚至可以调整偏移，以皮秒级分辨率及时移动 I 或 Q 基带信号。 某些函数发生器支持您执行更先进的调制，将噪声、随机抖动或确定性抖动添加到信号中。

What is a function/waveform generator?
456A function generator is an electronic test device that generates a variety of standard waveforms for a device under test (DUT), such as sine, square, ramp, or sawtooth waveforms. In circuit design and circuit boards, testing often requires the use of controlled signals to simulate routine operations. Testing physical systems and sensors often requires stable and reliable signals that are as low as a few microvolts and may be as high as...

How do I measure the current?
473Why do you need to measure current? In this article, we will cover the reasons for measuring current, how to measure current and what to look for when measuring current. We cannot see the current that is flowing with our own eyes. Therefore, specialized measuring instruments are needed to measure current and other parameters. But why do we need to measure current? And how should we measure it? This article will detail the reasons for the need to measure current...
