Hantek 6022BE 20MHz USB DSO
Fraser:
To add to my growing stack of Hantek test gear, I have just ordered their budget DSO, the 6022BE.
I have already purchased the 1025G Function Generator and 4032L Logic Analyser so I thought adding a basic oscilloscope would complete the set ;) It has two channels, FFT and 48Msps real sampling rate (single shot).
Make no mistake, this will be a very basic USB oscilloscope with only 48msps but it will have its uses none the less. Sadly no external trigger input is provided so one channel will provide the trigger. It does have the x-y mode that I need so that is a bonus. I see that there is an 'OpenHantek' project that may support this DSO in the future. An SDK is provided by Hantek.
Once the unit arrives I will provide internal pictures of it and a run down on the software performance. This DSO is not an alternative to 'real' DSO's with >1Gsps but at GBP49 ($75)delivered, its cheap enough to have in the test equipment inventory and competatively priced in the marketplace.
My unit is coming from 'Goodlucksell'

I expect this two channel unit to be 'cheap and cheerful' but the software quality, or lack there-of
will be the key to its usefulness. There has been a recent software update to fix some issues.

That 48Msps suggests something very common inside...
Fraser:
When you look at what you get for GBP49 it can't be a very expensive chipset inside the unit ?
I will let you know when I get it.
Fraser:
The 6022BE arrived today.
I have quickly whipped its clothes off to see what lives inside.
For GBP49 delivered I did not expect a lot but see what you think.
The key components are as follows:
1. CY7C68013A-100AXC
2. 24LC02 EEPROM
3. Dual Channel ADC with glued on heat-sink. Likely to be a 40MHZ AD device.
4. 2 Analogue input channels. Each contain 74HC4051, 5 pin 'HRA' amplifier, Qty 2 in cascade and a 3 pin 'A7' device.
5. AMS1117 3v3 regulator
There are positions on the PCB for another CY7C68013A-100AXC, 24LC02 and a SMSC USB2512A USB Hub. These would provide a 16 Channel Logic Analayzer function to the unit.
There is also a position for a 5V supply. Interestingly, the only components needed are a socket and a diode. There is no polyfuse in the external supply rail unlike the USB feed.
Pictures to follow.
Fraser:
Ok here are the pictures.
Nice PCB. It is laid out in a logical manner.
The parts count is relatively low and a CY7C68013 development board costs around $10 from China. But I still don't think I would bother to build one of these using such a board as the additional parts, case, scope probes and my time would make it far more expensive than GBP49. In those terms it is very good value for money. Next test will be to see how the unit performs with the infamous Hantek software package !
