Micsig Oscilloscope Probe CP2100A AC/DC Current Probe 800KHz 10A/100A with Standard BNC Interface

This is an excellent current probe at a fraction of the price of the "Big Name" instruments. Comes nicely packaged and performs as advertised. This is my third Micsig product and I haven't been disappointed yet!

Works as well as other probes that are three times the price. I use it with my Rigol DS1054 scope and am very happy with the performance. I find it accurate and easy to calibrate and use.

I have both of the cheap hantek clamps and this one is night and day. It doesn't float nearly as much as the Hantek does. The fact that it uses USB for power is a major plus, no more dead batteries. Thank you

Tektronix makes very good very high frequency (i.e. > 1MHz BW probes similar to this for measuring high bandwidth current signals with a DC average. But those probes can cost in excess of $3K USD with the special amplifier. This probe has much lower bandwidth, but for the price it is good enough for many design applications. I give this 5 stars because as of yet have not found as good a clamp on probe for the money that handles 100A peak.

Low phase shift and not too noisy. Useful at DC and up beyond the audio range. Probes this good were not available anywhere near this price just a few years ago.

It works great.

This is powered from USB jack and uses BNC connector to O'Scope input. Worked great for me!

Well made product with reasonable accuracy. Zero adjust worked very well and maintained 0 with no observable drift. I compared measurements against a much more expensive Agilent 1147A current probe and found performance to be very good. Negligibly phase shift in the measurement. Readings came in slightly lower than the Agilent, but were consistent up to 90A, so easy to compensate for this. 100A reading was about 7% lower and the LED started flashing and beeper sounded to indicate I had reached the measurement limit of the probe. I did some simple frequency tests using a function generator driving a 100 turn coil followed by a resistor to ground. The voltage waveform across the resistor was observed on 1 channel of a scope (which will be proportional to the current). The output of the probe was observed on a 2nd channel. Scope gain was adjusted so both channels were equal in amplitude on the display. Several frequencies between 20Hz to 10KHz were observed and amplitudes tracked very well over this range. I did not test further because the inductor - resistor combination was starting to cause the current to roll off. (This was due to my test circuit and had nothing to do with the probe.) I am happy with the quality and performance and am considering purchasing a second.

The amp clamp does work perfectly it has a good range and the waveforms are excellent, I would recommend micsig if your budget stretches that far.

Ottime prestazioni. Ottima qualità.

Ich habe den CP2100A Tastkopf mit einem Micsig Oszi TO1004 verwendet um die PWM Ansteuerung eines LED Betriebsgerätes zu messen. Das funktioniert sehr gut.

Bisher nicht ausführlich getestet, aber tut was es soll. Hat zwischendurch mal etwas gezickt gehabt, aber seither lief es wieder. Die Automatische Nullung ist aber nicht wirklich präzise, musste diese manuell über die Taster anpassen, welche nicht sehr intuitiv reagieren.

Boa relação preço qualidade, funciona sem problemas, até agora.
