Rigol Customer Research

[EEVblog]

Got an email from Rigol with a link to a customer survey with some rather odd questions.
Where is this 12bit Tektronix for $700? Or this 12bit Keysight for $1000?
It's just filled with odd comparisons that make no sense.
You might not be able to see it as the link might be unique:

Or the imaginary 2.5 GSa/s Siglent !

They are just hypothetical and made up specifications and costs to see what users value most when choosing a scope(brand, screen size, sensitivity...etc.)

A few months ago i received a similar survey from Tektronix. No comparison with other brands but also choosing from imaginary scopes. I think it was even more than 10 of those comparisons in the survey.

I guess this was a survey to find out which parameter is important and how much more would the customer pay for it. For example is the customer willing to pay more for 12bit, higher sample rate, more memory and so on. Or what would the customer choose if you could either have 12bit or more memory for the same price. So trying to find out which parameter is important and which is not.

For your Rigol survey it seems they also want to know how much the brand name is worth i guess?

They better have a very good AI engine behind it to reach some conclusions.

It is called (choice based) conjoint analysis. Has been around for a long time. The combinations are completely fictitious. At the most basic level, I think you would just run logistic regression on the choices. From the weights you can get an idea of the relative importance and the value of the individual aspects. No AI required.
