		<description><![CDATA[How good can a new $60 oscilloscope actually be? (Hantek 6022BE Review)
https://www.youtube.com/watch?v=8ts5J09Y7Gc

I routinely get viewers asking me for a cheap solution to help them fix old machines, so I decided to buy a Hantek 6022BE USB oscilloscope and see if it&#039;s actually sable. When I purchased it from AliExpress, it was just $60 shipped. Let&#039;s see if this thing is even good enough to be usable for fixing old computers.

I&#039;ve been using a National Instruments VirtualBench for the last several months, and while it&#039;s a fantastic piece of gear, it&#039;s extremely expensive so I do not recommend anyone purchase it.]]></description>

		<description><![CDATA[Hantek 2D72 vs. OWON HD272S – Which Scopemeter is Better?
https://www.youtube.com/watch?v=DTC1h2PWC8g

I did a detailed side by side comparison between the Hantek 2D72 and OWON HDS272S. Both of the Hantek 2000 series and OWON HDS200 series offer comparable specifications.  After watching this video you should be able to decide which one better fits your needs.

00:00 Introduction
01:36 Specification comparison
07:41 Power consumption comparison
12:43 USB-C port, probe compensation test point
13:50 Power-on power-off performance comparison
14:35 Update rate comparisons
15:54 Automatic acquisition speed, bandwidth comparison
21:03 AM/FM signals
24:12 X-Y mode comparison, Lissajous figure
26:42 Digital Multimeter comparison
29:36 Arbitrary waveform generator comparison 
34:34 Conclusion]]></description>

		<description><![CDATA[Mustool Scopemeter Review And Teardown
https://hackaday.com/2022/03/15/mustool-scopemeter-review-and-teardown/

There was a time when calculators became so powerful it was hard to tell them from little computers. The same thing seems to be happening now with multimeters. They now often have large screens and basic oscilloscope functionality. The specs keep getting better. While early cheap scopemeters were often relatively low frequency, many are now claiming bandwidths that would have cost quite a bit a few decades ago. A case in point is the Mustool MDS8207 which [IMSAI Guy] reviews and does a teardown of in the videos you can see below. It claims a 40 MHz bandwidth with 200 megasamples per second on a single channel.

The only downside in the claimed specifications is that the sensitivity isn’t great given that the lowest setting is 500 mV per division. Then again for a meter that runs under $100, any scope function would seem to be a bonus. The meter does all the other things you expect a meter to do these days, such as reading voltage, frequency, capacitors, temperature, etc. The response time of the meter is relatively slow, but you can get used to that.

		<description><![CDATA[thank you, i lik the article

Issues with input impedance and absolute measurements.
Not enough shielding – mains hum shows up if you are not careful.
Probe adapter can be better (try not to lose this small piece).
