High frequency current probe domestic flat for measurement: ETA instrument cost-effective choice

一、Measured background

In the field of electronic testing such as switching power supplies and new energy vehicles, AC and DC high-frequency current probes are essential tools, but the high price of imported high-end products puts users with limited budgets in a dilemma. This measured comparison shows that the measured measurement capability of ETA instrument ETA56033U AC/DC high-frequency current probe is not lost to imports, and the price is only one tenth of it, making it a high-quality domestic flat replacement choice.

二、Price vs. Parameter

Product primary stage, imported brand high frequency current probe price threshold is very high：

• Like CP031(100MHz/30A AC/DC probe) including tax is about 52000 yuan

• It is the same type of 30A imported probe from Germany and Tektronix, and the tax included generally exceeds 50000 yuan.

• The Rogowell coil probe for PEM AC in Britain also needs more than 13000 yuan and cannot measure DC.

The core parameters of ETA ETA56033U are solid.：

• Bandwidth：30MHz

• Measuring range: covering 5A DC, 30A AC

• Measurement accuracy：±1%

• Rise time：≤11.7ns

The core index of basic test can be compared with imported 30A AC/DC probe, and the market price is only about one tenth of the imported high-end model.

三、Measured waveform performance

In the oscilloscope measurement, the ETA probe and the imported products of the same grade test the same current signal synchronously, and the captured waveform is clear and complete without missing details. In the fast signal measurement such as switching noise and resonant current, the waveform fidelity is equivalent to that of imported products, and the measured performance is reliable.

四、Core Product Advantages

1.Ultimate value for money

Achieving flat core performance at less than a tenth of the price of imported products, with significant advantages in the current budget tightening.。

2.Strong ease of use, wide adaptation

• Clamp-shaped opening design, support non-invasive measurement, no need to disconnect the circuit, quick operation

• Narrow jaw shape, can adapt to narrow and dense test space

• Universal BNC interface, compatible with more than 95% of the market oscilloscope, plug and play

五、Summary

This selection test proves that high cost performance does not represent a compromise in performance. With solid parameters, excellent measured results, people-friendly price and convenient design, ETA instrument ETA56033U provides a cost-effective test scheme comparable to imported products for users such as electronics enthusiasts, university laboratories and start-ups.。
