Goupchn High Voltage Oscilloscope Probe P4100 with Accessory Kit 100MHz 2000V 100:1

I got this to use with my DS Touch oscilloscope, which has a setting for a 100x probe. It works very well and I use it on high voltage circuits with no problems.

Prior to purchasing this I had downloaded the software to get familiar with it. It's not as feature rich as say, the Pico but for my use I was willing to sacrifice that for more value from a hardware point of view. This scope is USB type c powered with fast data transfer, it's small and feels very premium. It comes in a nice case that holds everything well. The update speed is fast compared to the Owon I have. The wave sweeps smoothly across the graph and the triggers work as intended. I hope they update the software and add more features but for right now, it's functional and runs smoothly.

This is a 100X probe not a scope nor does it have a 10X switch. It does what it is intended for. Some people don't read. It can be used to measure up to 2,000 Volts DC and 2,000 Volts P-P AC not RMS. If your confused by the numbers or letters used above don't buy it nor use one. 2,000 Volts will kill you and hurt while it is burning thru you. RMS voltage times 2.8284 will give you Peak to Peak Voltage. 2,000VAC (RMS) is equal to 5,656.8 Volts Peak to Peak. So the limit for AC is 707.11 Volts RMS on this probe. And people hands off when measuring 2KV. It is a good probe and functions correctly and I like it!

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.

It arrived on time and they work great. Good price for the product

A passive scope probe is a very simple device, no need to spend $$$. I use this with an Analog Discovery 2 USB scope, and old Tek tube scopes. I'm sure it would work with just about any scope with 1 Meg input. The compensation range is fairly wide. The 10x/100x switch is handy. There's no probe readout scaling factor (extra side pin on BNC connector of more expensive probes) but who cares? I can easily multiply by 10 or 100 in my head. One word of caution, like all "high voltage" probes, the safe working voltage (i.e. no arc over) is reduced at higher (RF) frequencies. There's a voltage vs frequency derating graph in the instructions, be sure to double check that. But for audio signals, like tube amps, this is not an issue.

I have not tried this on high voltage systems yet, but tested it on my 120V line voltage at my house with my portable osciliscope and it works well, seems to be high quality and will be just the thing I need to check power on 3 phase 460V at work.

Received two probes. First probe failed after 3 months. Just started using other probe, so we'll see how long it lasts.
