Goupchn Oscilloscope Clip Probes 200MHz Fully Insulated BNC End Probe with Accessories Kit 1X 10X

So far so good. They seem like decent quality probes especially for the price. Pay no attention to the guy that says they don't have a way to perform compensation. He clearly didn't look very hard. I have not tested their 10x bandwidth yet so check elsewhere for that.

I have no clue if these really have a full 200MHz bandwidth, but they work fine for everything I've used them for, and you can't argue with the price. I really like some of the accessories. The spring ground pin thingies are really handy, and the little yellow covers are nice for probing in tight spaces.

Be prepared to make your own ground leads.

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.

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.

I had bought a 200 mhz Siglent oscilloscope, however there was a manufacturing defect in the probes. I contacted the company and they were sending replacement probes, but I needed probes to work on a project immediately. I ordered a pair of these probes. When they arrived I tested them thoroughly, I calibrated them and they appeared fine using the test signal of the scope, but I went further. I tried them on several complex waveforms that I was familiar with, and they delivered the signal to the scope with enough accuracy that I could not detect any difference between these and a much more expensive pair of Tektronics probes. The only little 'nitpicking' I have is that the BNC connector housing is larger on these (Just a little) because on these probes, the calibration adjustment is in the BNC connector housing, instead of the probe itself. Of course this also makes th actual probe slightly lighter and slimmer. I have always felt like the probe compensation was best done at the probe, so there would be a clean compensated signal coming down the leads to start with, however after comparing these with the manufacturer's probes (when they arrived) I could not visually detect any difference in the trace between them. (The manufacturer's probes were compensated at the probe.) These are inexpensive probes yet they do a good job at getting an undistorted waveform trace to the scope. I have not put them through the 'torture test' of surviving on my repair bench for several years so with them being inexpensive, I have a feeling they may not hold out very long, but with them so inexpensive, you can afford to replace them after a few years, and that is if they do die early. They might last a lifetime, especially if taken care of.

Probe comp is a little sketchy in 10x, perfectly usable at 1x. CH1 (white) is a Tek 6139A CH3 (yellow) and CH4 (blue) are these probes. The probe on 4 is corrected as best I can, adjusting simply overruns flat. Photo 1 is at 1x, photo 2 is at 10x. Comparatively speaking they provide a perfectly usable signal for most work.
