Goupchn Oscilloscope Probes Kit 200Mhz with Accessories Test Leads Kit BNC to Test Hook Cable 4mm Banana Plug to Test Hook Clip Leads

This works as advertised. I am using this on 2 O'scopes, my desktop and portable scope. After calibration, I verified the use against known waveforms from my test setup. For some and my hobby, these will do.

As a person who has used all manner of scope probes (Tek, HP, Agilent) for decades in a real engineering and repair environment, I can tell you that these are a pleasure to use and are well thought out. The tip hoods are unique in that they very lightly snap on which means they won’t fall off in the middle of a measurement or when the probe is clipped on and hanging…even the expensive ones don’t have snapping hoods and after a while lose the ability to hold on tightly. The tips under the hood are a little longer than most which is a good thing when the circuit point of interest is difficult to get to. The attenuation switches (X1-X10) are decisive which is often not the case with probes in this price range…..they don’t shift during gentle handling which is a big plus. The cables are soft enough that they are easy to maneuver on the bench….some probes use unusually stiff cabling and if you’ve ever had those you know what I mean. The hooks are the proper length and width to get under a component lead and the ground clips have a rubber hood covering most of it so as not to touch other areas of the circuitry. The rubber makes the ground clip a little more difficult to open but that also means it will grip tighter when released onto the chosen ground reference connection. The BNC female connector easily slides onto the scopes BNC male and locks nicely. They also come with 5 pairs of colored rings for probe ID which is nice in the event you buy 2 pairs for a 4 channel scope. We’ll worth the purchase price. My only negative, and it is very minor, but I’ve seen people overly whining about it, is, don’t bother trying to use the provided capacitance adjustment tool, it’s just too big for the job…instead, use a jewelers screwdriver (flat or phillips of the proper size) to make the overshoot/undershoot adjustment, and you’re done.

Works better than $1000 products from Tektronix. Excellent case as well. English on the box is a bit fuddled calls it a "deferential input" X-D

This is a good, cheap 100:1 probe. Capacitance at the tip, as measured at 100kHz with an LCR meter (see photo) was 5.8 pF. Rise time when driven with an 80 ps rise-time source on a 2.5 GHz scope using a 500 MHz-bandwidth high-impedance adapter, and with the probe tip probing the pulse source using a proper probe-tip-to-BNC adapter, was 1.08 ns (see other photo), implying a bandwidth ("0.35" method) of an impressive 324 MHz. Bandwidth measured using a swept sine wave from a 500 MHz arb gen agreed reasonably well with that figure, producing about a 260 MHz 3dB bandwidth. I use this probe for probing ultra-low-power circuits where I want to minimize loading, since at DC the impedance is indeed about 100 Mohm. At higher frequencies, the impedance becomes dominated by the capacitance of the probe and of the scope, which is why the rated voltage also goes down, but that doesn't concern me for my use case. I will say that I have casually checked the performance at 1000 VDC, and nothing went boom. Overall, would buy again.

I bought this to make a single measurement that demanded a differential probe. It worked perfectly, absolutely drop-dead simple to use. I'll hang onto it just in case I need to make another such measurement. But... The case it came in is so overkill it's irritating. It certainly protects the probe and its accessories, but takes up too much space to do so. It needs to be redesigned for much more compact storage. No part of the probe needs to be set in a huge foam block. It could all be stored much more compactly and the case size cut down to half or less volume.

These are excellent quality probes for the price ! I have not tested the high end of these 200 mhz probes yet but I feel confident they will preform quite well.

Great quality probe! 1x 10x

Arrived today, was a great buy for my 100 MHz scope band width was more than I expected.

The specification for this item under the Additional Details topic specifies that the probe in 10X position has probe compensation of range 15 to 45 pF. I cannot find any facility to enable probe compensation. I particularly selected purchasing this probe because of the compensation facility. For almost every situation probes will require compensating to suit the scope input, certainly for the DS212.Without this for virtually every situation the probe in 10X is practically useless. Buyers should be aware that the majority DO NOT HAVE COMPENSATION. BEWARE!

Muy bien y muy económico, aunque es más para uso en laboratorio y no en campo ya que se sienten algo frágiles como para un uso rudo.

Good

Works great, good price.
