I saw a video comparing the HDS272S to another brand. In that video I learned how nice the Owon was. My needs are a little then most but I ordered the HDS242S. What a great hand held oscilloscope. I am so happy with it. Barry
Having received a 2102S from Amazon, I actually got 2 (two) 100Mhz probes included. One was a 6100, and the other a 3100, which is grey vs the black of the 6100. From what I can tell, they operate the same. It's a nice scope, easy to use. Weighs about the same as my Fluke 75. I appreciate your review of this.
Thanks for the review! Mine just came in a week ago, from aliexpress. I ended up cancelling my banggood order because they kept delaying the ship date, from "ready to ship" to eventually 40 some days. The device is fantastic. I'm genuinely amazed by the price/performance ratio. Only complaint so far is the direction pad input directions seem backwards. I think all the expensive chips in these devices are usually copies. I do wonder who is making them.
I agree about the "direction pad input" for the vertical and horizontal, as it is counter intuitive to have the left-right buttons control the vertical gain and the up-down to control the horizontal timebase. Why is it that so many items do so well with everything else, but then have one annoying fault such as this? 🤢
The chips are copied from Texas Instruments and they are made by communist kids with hammers and chisels! Do you remember those robotic children playing huge guitars moving like robots and lifeless!? Is a common sight in North Korea at Kim John Un parties! Well those are the Asian kids making the chips!
Another fantastic analyzation of a OWON handheld. I hope OWON offers test accessories for the HDS series scopes soon. I like the idea of a all in one to test motorcycle electronics. Everything from pulse generators to secondary current. Even wire continuity stability issues with a single pinch. Bravo!

Kerry, thanks for these detailed reviews - definitely a terrific resource that I use to support my own purchasing decisions. One question that came to me during this review was if you gave consideration to screen brightness and the impact it may be having on power consumption on the newer HDS2101S? The brightness of the newer model was something I noticed immediately in the side by side section and when you measured consumption later in the clip I was left wondering if your process took that into consideration (e.g. set screen brightness on all models to max/min/default setting). It does appear the newer model could be notched down slightly to match the equivalent brightness of the HDS272S in which case perhaps that makes up for some of the distinctly higher power consumption of the HDS2102S?
I recommend the author to become a commentator at football matches because of his voice, good speech and good knowledge of the subject. What is the difference between commenting on a match and reviewing? Thanks for the review.
It would be nice if you could have tested to see if they made any improvements to the DVM function as far as time to read resistance and capacitance and the minimum capacitance value as well, but it was good to see what you did check as far as frequency specs and power consumption.👍
Looks like OWON released a new series already, the HDS300, different case, some more memory and few extra functionality. I wonder if they improved the acquisition time for Multimeter functions.
That was a while ago. They have also released the HDS400 series. These scopes definitely have some unique features, like RS-232. You can see a review from 2011 of a HDS300-series scope here: th-cam.com/video/6td9kVKWGFw/w-d-xo.html

I'm assuming the DMM display/behavior is the same as the HDS272(S). Another video reviewing the HDS272(S) complained of the lack of an analog-scale for the DMM mode... and the fact that display shows moving digits while the display settles after changing ranges without any other annunciator. LIke - they could do a software update for that. So it seems like a quality hand-held scope, but lacks a bit from some of the most basic DMMs. If anyone has one of these and the DMM mode is better than the HDS272(S) -- please let me know...

The hardware and build quality of these devices is OK for the price point. The problem with them is firmware. And Owon customer service that refuses to suply updates. Edit: 4 days later Owon started to suply updates for these devices. Nice.
that means if you email them directly they wont give any firmware updates? that is some real bullshit they should get their hardware hacked from people to open up all bandwidth available instead of just not software support....

@@MoesKeckeEcke In this video at 11:05 Kerry is testing 100MHz signal. Are 4 divisions between peaks instead of 5 divisions. 4 divisions equals 8ns, that means 125MHz.
I think your current consumption statement is off by three orders of magnitude: mA means milliamperes, not microamperes. This thing has a power consumption spec of 6W.
@Kerry Wong how important is the sample rate? Would you recommend the HDS2102S with 500MSamples or the HDS272S with 250MSamples? How good is the signal generator, should I buy the S Version or a separately signal generator instead?
Wish it was just a scope and not a DMM too. I can carry 2 tools no problem. Wish they made one with a built in RF frequency meter with pull out antenna
I am an automotive and marine technician. Since I like the eases of portability, can you help me to decide. Can the HDS2102S handheld perform the functions as the VDS3104 which requires a laptop computer?
These scopes do not have decoding capability so while they can capture the signal it would be difficult to narrow in what you are looking for without decoding.
@@KerryWongBlog thank you, we have a picoscope,but was looking for something more portable that could use to confirm presents or absence of a clean signal at a particular module etc. Would this device work?
@@keanMechanic Hi, did you happen to buy the HDS2102S and test it to see if it can keep up with the Picoscope in terms of the ability to test the various sensors like cam, crank, wheel speed and if it's suitable for use with a current clamp using the scope interface for relative compression test. It would be pretty awesome if it can handle a pressure transducer, of course, it will never be as good as the Picoscope.
Would you say this is a good model to start with? I do basic electronics repair, and looking something like the multimeter / scope option-built in. (Still learning how to use an oscilloscope) ty
Hi, thanks for the review. Your purchase link takes you to a page that has a picture of the "S" version, and seems to describe it, but appears to only have the model number: HDS2102 implying no waveform generator. Any thoughts on what model this is?
Any chance if you happen to know whether the non “S” model boards were Identical except for AWG Chip (i.e. had all the other component support in place ) or whether all the architecture was identical and the function locked on the firmware side? Purely curiosity in this case, I’m not about to deprive a manufacturer of an extra $30 when they are currently producing a portable oscilloscope of this caliber at a compelling price point. Even if the functions were limited through firmware, short of the fix being to download and install the “S” versions firmware update instead, I’m not so desperate to save $30 as to waste my precious few free hours looking into it nor do I want to discourage others from giving less financial resources to companies who are ACTUALLY PRODUCING GOOD PRODUCTS @ REASONABLE PRICES. I’m not worried that a simple software update is all it takes but it’s good hearing confirmation.
It will depend on what you are trying to do in the short term. If you are unsure, I'd suggest get a scope well within budget and once you gain more experience you can decide on what to get next.
@@KerryWongBlog IM NOT going to build anything basically I'm sound engineer, so I needed it calculating the watts and checking distortion of amplifier looking for stable and little bit accurate oscilloscope for my work😃😃😃
I found it in the manual of the scope "The two channels of the oscilloscope are non-isolated channels. Note that the channel should use a common reference when measuring, and the ground wires of the two probes cannot be connected to two non-isolated places with different DC electrical levels, otherwise it may cause a short circuit due to the ground wire connection of the oscilloscope probe."
just bought the HDS2102s from aliexpress. Questions. instead of just turning on 2 channels and measuring one. What happens having both channels connected to 2 different signals? will still be as accurates as your tests? The signal generator is a little frustrating, trying to set duty cycle on a pulse wave. anyone figure that out?
When both channels are on the sampling rate is halved. But it shouldn't affect measurement accuracy as long as the frequency of the signals are within the spec'd bandwidth.
Will the smallest model 242 good enough for most applications? As this is a go to Oscilloscope I am more keen on the cheaper the better for this application. Your comment most appreciated.
It really just depends on the type of signals you're going to scope. 40MHz bandwidth will be serviceable up to about 10MHz for most uses. So for things like audio, pwm dimmers, and switch mode power supplies you'll do just fine.
#1: No fine vertical settings (scope), #2: Does not retain last settings when turned off (scope). Other than that it is fairly descent. Returning to Amazon because of my #1 and #2, especially #2. Not remembering its last settings and having to set it back up from scratch every time you turn it on is a killer.
@@jalius7878 It's working now. Maybe the battery wasn't charged enough to save last settings before? Maybe it just doesn't save last settings intermittently. No fine vertical gain is just plane weird. The DVM is about as good as the old free harbor freight. Continuity test is not real fast. It would be difficult to hold one probe to say B+ and drag the other one to find where it connects to the chip, unless you drag slowly. I am returning it tomorrow. I was real excited but wanting is better than having. I guess there is a reason a portable battery operated 100MHz Siglent Scope meter is $800.
This is not a review. The oscilloscope must be checked on a square wave. At a frequency close to maximum. It is not clear how much it distorts the signal.
@@АндрейАльтов , my problem was with you saying "at a frequency close to maximum." For 10 MHz square wave signal, 100 MHz analog bandwidth will allow ten 11 harmonics (from 20 MHz to 100 MHz) without attenuation. Get yourself a 1000 MHz scope for a displayed 100 MHz square wave. It will be very expensive...
i been wondering about asking someone who worked with owon before, i even made a thread on eevblog forum but i will ask you too , what do you generally think about owon build quality and support, i been looking for new scope and one of the options was 4 channel sds 1000 unit from rebadged owon brand, because it is the cheapest 4 channel 1gs/s 100/150mhz scope on my local market, and 2 channel version is cheaper than firnsi 1014d

It really just depends on the type of signals you're going to scope. 40MHz bandwidth will be serviceable up to about 10MHz for most uses. So for things like audio, pwm dimmers, and switch mode power supplies you'll do just fine.
Verry good 👍
cool !!!
The memory depth, is it 8Kbit or 8000 points?
#1: No fine vertical settings (scope), #2: Does not retain last settings when turned off (scope). Other than that it is fairly descent. Returning to Amazon because of my #1 and #2, especially #2. Not remembering its last settings and having to set it back up from scratch every time you turn it on is a killer.
Did you try the save button? I'm on the fence about buying this model.
@@jalius7878 It's working now. Maybe the battery wasn't charged enough to save last settings before? Maybe it just doesn't save last settings intermittently.
No fine vertical gain is just plane weird.
The DVM is about as good as the old free harbor freight. Continuity test is not real fast. It would be difficult to hold one probe to say B+ and drag the other one to find where it connects to the chip, unless you drag slowly.
I am returning it tomorrow. I was real excited but wanting is better than having. I guess there is a reason a portable battery operated 100MHz Siglent Scope meter is $800.
This is not a review. The oscilloscope must be checked on a square wave. At a frequency close to maximum. It is not clear how much it distorts the signal.
At your desired frequency, obviously it will not be displayed as a square wave. This is basic physics, not a problem with the product.
@@michaels3003 Yes. This difference shows the quality of the device. The closer the square wave is to the ideal, the better the device.
@@АндрейАльтов , my problem was with you saying "at a frequency close to maximum." For 10 MHz square wave signal, 100 MHz analog bandwidth will allow ten 11 harmonics (from 20 MHz to 100 MHz) without attenuation. Get yourself a 1000 MHz scope for a displayed 100 MHz square wave. It will be very expensive...
@@michaels3003 Professional devices are always expensive.) On entry-level devices, many signal harmonics are not visible.
i been wondering about asking someone who worked with owon before, i even made a thread on eevblog forum
but i will ask you too , what do you generally think about owon build quality and support, i been looking for new scope and one of the options was 4 channel sds 1000 unit from rebadged owon brand, because it is the cheapest 4 channel 1gs/s 100/150mhz scope on my local market, and 2 channel version is cheaper than firnsi 1014d
What the hell is that noise when you started to use 50 MHz generated signal? Is awful!
Looks like a failed diode D4 under the display.
a 200MHz version exists
Yes, I just did a review on it.
I bet Mr Wong in here is from China
The name Owon and the term "The Best" should not be used together. Owon is a cheap toy in the electronics world.
Thanks! You got me interested. I wait test with difficult signals on 30-100 mHz. I want choose between this or DSO2D10.
What did you choose? I am facing the same choice! Thanks
@@kariemmohamed1446 New model HDS2202 200MHz.
@@0000Vlad0000 Thank you very much for your quick reply! May I ask What is the main thing you choose over a bench oscilloscope?
@@kariemmohamed1446 a) 100% galvanic isolation. b) small size and weight for emergency evacuation
@@kariemmohamed1446 it is convenient to service machine tools, cars, overall machinery
