I settled down to a nice evening of #electronics, and my #Hantek #DSO4254C oscilloscope is failing to boot. Have tried a firmware file I found, but to no joy. 😢
Speaking of #electronics, I managed to do a software upgrade of my #Hantek #DSO5102P #oscilloscope. They basically threw the same ingredients in three different scopes, with different price tags and firmwares allowing for 70 MHz, 100 MHz and 200 MHz sampling rate respectively. Unaware of this, I went for the sweet spot and bought the 100 MHz model, known as the DSO5102P. With a little fidgeting, I managed to gain access to it's #Linux console and patch the firmware, convincing it that it's now a 200 MHz #DSO5202P model, allowing twice the sampling rate. I don't need it AT ALL, but boredom makes you do weird things! 😆
Explosion-Scarred Scope Gets Plastic Surgery Hackerspace Style

Some equipment comes with a backstory so impressive, you can’t help but treat it with reverence. For instance, this Hantek scope’s front panel and knobs have melted when a battery pack …

$60 PC Oscilloscope Review

Owning an oscilloscope is a real gamechanger and these days, scopes are more capable and less expensive than ever before. However, there is a big difference between scopes that cost several hundred dollars which are usually quite good and many of the very inexpensive -- below $100 -- instruments that are often -- but not always -- little more than toys. [Adrian] looks at a PC-based scope from Hantek that costs about $60. Is it a toy? Or a useful tool? He answers the question in the video below.

The Hantek 6022BE sports two channels with a 20 MHz bandwidth and 48 million samples per second. The device included probes, too. Of course, you also need a PC, although there is apparently third-party software for Android if you don't want to lug a laptop around.

With two channels and relatively low bandwidth and sample rates, this Hantek is not going to displace a good benchtop scope, but you aren't going to get one of those at this price point. The question you have to ask yourself is what do you actually need? In [Adrian's] case, he wants to work on things like Commodore 64 computers, so 20MHz should be just fine for that sort of thing.

The software looks a bit dated, but it does have a lot of features you'd find on traditional scopes. The triggering, however, wasn't very capable but since the device uses USB2, you can guess that the triggering is all happening in the device which probably can't handle anything too complex. The results matched fairly well with a more capable instrument that [Adrian] had on hand.

The verdict? [Adrian] thought it was probably worth the money, but did wish for some things to be better. Many commenters, however, urged him to try unofficial software for the device which is supposed to be much better. We weren't that interested in the device as an oscilloscope, but given that the protocol is apparently understood, we wondered if it might not find a home as a cheap data acquisition module in some future project.

We've seen reviews of Hantek's scope meter recently. We are always on the lookout for what kind of scope you can get for under $100.

[Kerry Wong] is Really into Scope Meters

If a combination multimeter and oscilloscope is on your holiday shopping list this year, you might want to have a look at some of [Kerry Wong's] recent videos on the subject. Over several videos he looks at -- inside and out -- an OWON HDS272S and a Hantek 2D72, both reasonably inexpensive entries in the field. Both instruments are similar and have a few variants depending on the frequency capability and the addition of a waveform generator.

There are several videos on the Hantek device that are a few months old, then some recent videos -- like the one below -- on the OWON device along with some comparison videos.

In general, it seemed like [Kerry] had a slight preference for the Hantek in some areas like the user interface and software options but concluded that the OWON has better performance both in the oscilloscope and signal generator. As meters, the OWN is a 20,000 count true RMS meter, but the Hantek is only a 4,000 count and does not have true RMS. We really enjoyed seeing both devices looking at the same signal side-by-side.

We had looked at [Kerry's] take on the Hantek awhile back, as you may recall. Cheap portable scopes have come a long way since 2016, you have to admit.
