This oscilloscope is excellent value for money. Several functions included are only available on higher-priced oscilloscopes. . . Protocol decoding/triggering, segmentation/recording memory, depth memory. After an additional fee, the oscilloscope can be expanded to have a 16-channel logic analyzer or to control a Siglent AWG. The quality seems pretty good. Of course, its quality is different from the quality of the main oscilloscope I use in my work, and the cost is 20 to 200 times higher than this one, but its quality is reasonable. It is very light and suitable for sitting on a bench. I found some bugs and hope to fix them in a future software update. 1. When inserting a file from the oscilloscope 2 into the PC, the USB drive is damaged (but no file is lost). Several Problems in the Decoding of Serial Bus

If you need an expensive oscilloscope, this is hard to beat. I need something tolerable, it has 4 channels to monitor several parts of the amplifier. I am a little skeptical about a brand I have never heard of, but it is much cheaper than a major American brand, and I think it is worth a try. Overall, it did a great job. A bit noisy, but not too bad, and the price is reasonable. The user interface is not difficult to understand, and I made useful measurements within minutes of powering it up. The fan is a bit loud, but not loud enough to be annoying. I am very impressed with all the "add-ons" they have installed in it. In particular, signal decoding (CAN, I2C, etc.) usually does not appear in the range of this price level. I haven't tested any frequency higher than 8mhz, but I bet it will also work at high frequencies.

Like most reviewers, I am very satisfied with the basic hardware and software of this oscilloscope. I purchased it for a special set of measurements, and I did encounter some troubles, which I will describe below. However, after contacting the customer service staff, the problem was resolved within a few weeks. very happy! The measurement I need to make is to monitor the two voltages and two currents that occur during the startup of a particular arc lamp. These voltages and currents are alternating-usually in the range of 20 to 60 kHz. The starting process of the lights takes a few seconds, and I need to monitor the whole process by starting each light. Therefore, I use an oscilloscope at the maximum memory depth, each of the 4 channels has a 7-meter point, a sampling rate of 1 MHz, and a tracking time of 7 seconds. The oscilloscope performed well when acquiring data. The scope can store data in two different text file formats, or as binary data. As one might expect, the use of the text file format is very slow: it takes about 5 1/2 minutes to write a single waveform capture to a MATLAB file, and it takes about the same time for my best computer to read the file! Therefore, it takes about 12 minutes for me to turn on the light every time, just to input the data into the computer in MATLAB format! (Once in the computer, I can store it in binary MATLAB format within a few seconds.) Of course, the oscilloscope binary file output is much faster to use, but the binary file format generated by my oscilloscope is consistent with the manufacturer’s website The provided documentation does not match. (Not even close yet!) This is the problem I contacted the manufacturer to solve. A few weeks later, the manufacturer provided a document containing the correct binary file format information, allowing me to complete the work in a reasonable time.

Since the service department gave me an old Tek 545 O-scope/room heater, later logic analyzer and spectrum analyzer, I have been using test equipment. All bench pigs and cheap diners. When the personal computer came out and invested in IT support, I started to use desktop technology. Just returned to audio work, can't believe that they pack all the features into this range for $500. 4 full-function vertical channels, storage function, remote access, external storage can be expanded, and even mathematical functions including Fourier transform. You can even use a dongle for logical capture. When I was working, I wanted to have something like this, as a hobby to support-the best toy ever!

This is to teach our grandson electronic technology. As a retired electronic technology/field service engineer, I have two old Leader LB-302 portable oscilloscopes from the late 70s hidden in the garage, but after 35 years of use, they are all dead. I think I will move on and jump to something more popular, wow, I am surprised by this unit. The size is good, the display is large, and the synchronization is stable. I'm still thinking about the knob. This is more than I need for a long time to come. Very good fit and finish, very good packaging.
