" alt="" class="bbc_img" />The Hantek DSO2D10 is a low-cost two-channel digital oscilloscope with a built-in arbitrary signal generator. It belongs to Hantek's new family of low-cost oscilloscopes. Models are available with a generator - denoted by the letter 'D' and without a built-in generator - denoted by the letter 'C'. The family includes oscilloscopes with a claimed bandwidth of 70, 100 or 150 MHz. The described model has a declared bandwidth of 100 MHz.
We have to admit that, for a device costing less than $200, the parameters seem quite satisfactory. My doubt is that in models with declared bandwidth of 150 MHz the sampling rate is only 1 GSa/s (500 MSa/s in dual channel mode). This seems too low to reproduce the waveforms well.
Oscilloscope:
Bandwidth: 100 MHz
Sampling rate: 1GSa/s - single channel, 500MSa/s - dual channel
Maximum record length: 8Mpts - single channel, 4Mpts - dual channel
Time base mode: YT,XY,Roll
Rise time: 3.5ns
Mathematical functions: Add, subtract, multiply, divide, FFT
Clipping windows for FFT: Rectangular, Hanning, Hamming, Brackman, Bartlett, Flattop
Screen: 7", 800x480 px
Built-in generator:
Resolution: 12 bit
Sampling rate: 200 MSa/s
Sinus frequency: 0.1Hz to 25 MHz
Number of available arbitrary waveforms: 4
Arbitrary waveform length: 8 KSa
The decoding of UART, LIN, CAN, SPI, IIC transmissions is a positive feature. Measurement can also be triggered using the above interfaces. Although the record length of 4Mpts (for two-channel mode) does not allow observing long transmissions, the possibility of decoding messages should be considered a definite plus.

I placed my order in China in mid-December when the oscilloscope still had preorder status. I had to wait for shipment almost until the end of January. The device itself arrived in good condition, solidly packed. I had the package at home about a week after shipment.
The first impression was moderately positive - the build quality is simply correct. Nothing creaks, nothing squeaks, the plastic is thick and feels solid. The knobs work smoothly, with a nice "jump" but could be more stable. Slightly annoyingly, the USB connector is mounted upside down. Apart from these details everything seems to be in perfect order. The device itself looks just nice but that's a matter of taste.
After starting it up and playing around for a while, we can say that the oscilloscope works as it should. Unfortunately, I do not have access to an external generator, so I based my measurements on the one built in Hantek. Certainly, the multitude of functions is satisfactory, in the oscilloscope itself you can adjust many settings related to display, data acquisition or measurement settings.
During several hours of play, it happened twice that some menu function got "stuck" - it was impossible to change it. Entering another menu and returning to the jammed function helped. It also happened that the "Auto set" function selected completely wrong settings.

Overall, my impressions are quite positive and, for the price, the oscilloscope behaves correctly. The problems detected so far are related to the oscilloscope software, so one can hope that the manufacturer will fix them in a newer software version.
