How to promote an USB oscilloscope to individual engineers? I am the Loto instru

thanks a lot ,very usefull suggestions

thank you , i learned to fix the video problem just now ,it's ok now
Rerouter:
Some of the better points you have working for you is a standalone device in a similar market is $400 AUD, if your attacking at a lower price point then as long as it has equivalent or better functionality, then the user cost of having to have a computer on hand to use it can be overcome.
Bonus points if the software doesn't require an installer or admin privileges to run. so it can be used on whatever computer is available instead of one you lug around.
Key points that i cannot see at a glance on your marketing material
- Is the USB draw less than 500mA under all conditions? (A number of laptops will disconnect the port if more is drawn)
- What is the memory depth of the device (I assume 128K from one image, but that uncertain)
- What is the resolution of the ADC (8 bit, 12, 16? more?? and what is the effective resolution, if your 16bit ADC is only repeatable to 14, then it would be a 14 bit scope)
- What decoders are supported (one of your images hints at it, but "what we are interested in" doesn't really cut it. This is where you can make a large lead over standalone scope)
Then there is just technical translation, like "afterglow" on your notes is commonly refereed to as "waveform persistence" in English technical literature.

Hi ,Rerouter .Thank you for you suggestion.
Yes,it can used on any computer with windows ,especially for win8,win10, on which do not need driver installation.but you need a appliction software. I suppose nowadays , almost every engineer has a computer ,so i build this kind of product for virtual instruments.
sure ,it draws about 170mA current from the USB hub,so we don't need to worry about it, it much less than 500mA.
Yes,it's 128K ~ 2G depth. 128K for hardware chip storage,but 2G is for computer harddisk,when you sample slow, it stores data directly on harddisk.
8 bit ADC for each channel.
for now ,i just developed iic and rs232. other decodes may be later for free.it's just software function, customers download a new sw to fullfill it.
i put tow decodes in the attachment.

In the video you try to look at a waveform with x1 probes that is relatively high frequency... Why? Are you trying to show me how not to use an oscilloscope? If they're both supposed to be 1Mohm inputs I'd fault your scope on the basis that they have different amplitudes. Why would you look at a 25MHz signal 4Vpp and switch to a v/div range that maximizes error? That whole video should be trashed. It seems poorly thought out, poorly edited, and deceptive. You could at LEAST make sure the v/div and time/div settings are the same. Why don't you have a x10 or x100 selection for software? For comparisons I'd also prefer you do one at a time with a direct connection if you want to look at x1 performance or at least a splitter. Although the whole exercise is lost on me, are you trying to say the probes you made are better than rigols when switched to x1?
