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

jiangtao.lv if you want to make some usb oscilloscope bestseller, you can do it by implementing SDR DDC receiver mode inside your oscilloscope. It's not so hard, just needs some more FPGA programming. Because input amplifier, ADC and FPGA is already present in the oscilloscope hardware.

If you can provide users with ExtIO DLL which will acts with your usb oscilloscope hardware to use it from HDSDR software as SDR DDC receiver, and you can keep the price low, your product will be bestseller, the same as RTLSDR dongle :)

Do not be discouraged by many of the responses here. You have come to a forum full of engineers. Engineers do not know how to write politely and with consideration. They can be quite rude. However there is still good advice to be found in what they have written.

Thank you very much for your kind comfort.It's very kind of you.I think  I'm old  enough to be stimulated by these sharp advice.
I won't be in a mood swing because there is good advice as you said.This kind of environment makes me feel familiar,it is also true of the Chinese engineering community.

thank you , I will try to learn and think about it. :D

jiangtao.lv in addition to SDR DDC mode, there are more similar features that you can implement in your USB oscilloscope to make it very popular.

For example, you can add the following functions to your device:
- arbitrary wave / multi-function generator (just by adding DAC)
- frequency meter
- spectrum analyzer
- vector analyzer
- antenna analyzer
- frequency and phase response analyzer
- LC-meter
- reflectometer
- SDR DDC receiver
- QRP SDR transceiver (use ADC+FPGA as SDR DDC receiver and DAC+FPGA as SDR DUC transmitter)

Also, you can implement stroboscopic oscilloscope mode in order to measure periodic signal with frequency which is much higher than ADC sampling rate.

All these functions are very high demand for amateur and hobby electronics peoples. And your device with these functions will be very popular.

All these functions can be done just in software, and you can make total unit cost smaller than $50.

For example, you can see this one: http://www.osa103.ru/en/main-page/
As you can see, this device is very cheap and simple, but provides a lot of professional-level functions.
And with extension board it allows to measure frequencies up to 6 GHz.

As you can see, this device uses just two expensive IC (FPGA and ADC), but it can replace a bunch of professional equipment.
This is what users expecting from USB oscilloscope.
Not just "yet another cheap usb oscilloscope", but a real useful and multifunction device.

Here is PDF with schematic of OSA-103 device, as you can see it may be even less complicated than your USB oscilloscopes, but it can beat your oscilloscopes with a lot of very needed functions, implemented in software.
And it can beat even professional equipment. :)

I am not sure if Gary.M's comment was directed at me, but re-reading my post I can see how it could come across as very harsh. Sorry about that.

I do this for a living (or at least part of it) and treated this as one more document review that I usually do in my day-to-day life. Unfortunately I forgot this was not part of an over-arching discussion where the tone is set well before the actual comments for changes. I will be more subtle in the future.
