Thank you. This video is one of the best HDS272S reviews I've ever seen. Yesterday, I bought the HDS272S scope and it started shipping. Siglent's handheld oscilloscope was discontinued last December and I'm going to use this OWON scope while waiting for a new model to go on sale. I got a lot of information from the video and I saw a lot of answers in the comments as well. As a result, OWON doesn't seem to be enough for my needs.

They now make a 100mhz BW version with 500ms sampling rate. Same Freq Generator though. I suspect that the 40mhz version might be software hackable to 70mhz as both have the same sample rate.

Great review. I bought this back in April 2021 and have been using it daily since then, and I think it's really good for it's price. Don't think you can find a better 3-in-one unit at a price comparable to it. But you'rr way to quick with removing the leads when you test things, this instruments needs more time to make a reading than "normal" multimeters do it seems like. That's also the reason why you struggle with measuring capacitors. You just didn't give them time to charge up. The only thing I don't like is that it doesn't look like Owon is pushing out Firmware updates to these units.

Yeah, the capacitance range is extremely slow and there is no visual feedback on the screen indicating the measurement is still going on. But for occasional use shouldn't be an issue.

@@Scott_6666 That's not how current and voltage measurement work. If you connect a meter to make a current measurement, but accidentally use the voltage terminals, virtually no current will flow since the meter impedance is very high - typically 10MOhms. Depending on the load, the meter will normally see the supply voltage and you'll wonder why your load isn't working. The current terminals on the other hand, are a practically a dead short. If you attempt to measure the voltage of a low impedance power source with the leads in the current terminals, the very best outcome you can hope for is a blown fuse. Connect it across the mains for example and thousands of amps can flow whilst the fuse is just starting to think about blowing. Things can get very exciting very quickly.

I found a flaw in the oscilloscope with fast pulses at low frequencies (short duty cycles). The sampling rate at 1 sec/div is 500 Sa/sec, which is acceptable for a waveform with a bandwidth under 250 Hz. However, a 1us pulse with 10 secs period is not measured correctly.

Yes, I forgot to mention that in the video. the Hantek 2D72 (I have a comparison video if you haven't watched yet) does it properly. A couple of folks asked about that I was debating whether to make another video to point this out... Also, under 50ms/div the OWON automatically changes to ROLL mode.
@82sledge3 жыл бұрын
This scope has memory up to 8000 samples. I am preatty sure you could measure this pulse quite precisely (Normal mode, appropriate time base for 1us pulse, e.g. 500 ns/div), but NOT with the whole period, just because of the low memory. But one finding - if you switch acquisition mode to sample, you can have issues with alliasing at long time base settings. But with Peak acquisition mode, it seams that te scope is able to display like span of Peak-peak values within sampling period so in this case HF signal will not disappear as with "sample" mode....

I am not seeing that option either. Now to be honest, I have rarely used the RMS measurement on other scopes that have it. It is pretty easy to derive from Vpp for most common waveforms. That said, I agree it should come as standard (interestingly, the Hantek 2D72 I reviewed a while back is also missing this feature, coincidence?). The "mean" measurement seem to measure the "arithmetic mean" of the signal (e.g. DC offset).

Normal and single mode available as well. The refreshing rate of the display might be like 50 Hz or lets say display speed like 20 ms (based on the shade of moving trace)
