The importance of oscilloscope analog front end design in hardware design
The analog front end ACTS like the lens of a camera. Many photography enthusiasts use SLR cameras, not least because their lenses have better optical properties. Similarly, the analog front end attenuates and amplifies the input signal, and the system noise is amplified. If the analog front end design of the oscilloscope is poor and the system noise is large, the tiny signal which we hope to test will not be captured.If observed in frequency domain, these noises will reduce the signal-to-noise ratio and increase the bottom noise. If the isolation degree between signal channels is not enough, the signal of other channels will cause great interference to the measured signal.Meanwhile, linearity and anti-saturation ability of the simulation front end are also very important.
High resistance passive voltage probe of oscilloscope
According to practical needs, voltage probe is the most used, among which high resistance passive voltage probe accounts for the most. Passive voltage probes provide various attenuation coefficients of 1×, 10×, and 100× for different voltage ranges. Among these passive probes, 10× passive voltage probe is the most commonly used probe. For applications where the signal amplitude is 1V peak-to-peak or lower, a 1× probe may be appropriate or even necessary. It is much easier to switch a 1×/10× probe in applications where the signal mixture is low amplitude and medium amplitude (tens of millivolts to tens of volts). However, the switchable 1×/10× probe is essentially two different probes in a product, with different attenuation coefficients, bandwidth, rise time, and impedance (R and C) characteristics.Therefore, these probes do not exactly match the input of the oscilloscope and do not provide the optimal performance achieved by the standard 10× probe.
