How does an oscilloscope work?

February 14, 2025common problems 8300

An oscilloscope uses a probe to connect to a test point in a circuit and amplify or attenuate the voltage at that point. The subsequent signal path depends on the oscilloscope, but in general, analog circuits condition the signal and analog-to-digital converters digitize it for further evaluation, processing, and analysis.

How does a vector network analyzer work?
February 14, 2025 906
A network analyzer consists of a signal source and a receiver. The receiver will detect changes in the output signal of the device (or network) and then compare it to the source signal fed into the device. To evaluate the effect of the device on current and voltage, the VNA measures the resulting amplitude and phase response. This results in transmission and reflection measurements, impedance and s-parameters, which can be used by the test engineer to...

The selection criteria for a VNA depends heavily on the application or usage scenario. Typically, selection criteria include frequency range, number of ports required (from 2 to 24 (multiport) and even 48 (with switching matrix)), output power, and instrument class from economy to handheld to high-end. Vector network analyzers are both signal generators and receivers...

What can a signal analyzer do?
February 14, 2025 1049
Signal analyzers are capable of measuring the amplitude and phase of an input signal at a single frequency. The Signal Analyzer combines the large dynamic range of a swept-tuned spectrum analyzer with the power of a Vector Signal Analyzer (VSA) to perform in-channel measurements, such as Error Vector Magnitude (EVM) measurements, which require both magnitude and phase information. The VSAs are available in a wide range of sizes and sizes.

How do I measure voltage?

How do I measure voltage? If you use a multimeter, anyone can measure it easily ■ Summary Since voltage is not visible to the naked eye, it is not possible to confirm "how much voltage is flowing through a circuit at a glance". However, the circuits of electronic devices have a set voltage for normal operation, and if the voltage is too high, it may lead to product malfunction or personal injury. In addition, ...
