Obtaining Bode Plots for SMPS Feedbackj loop?

[grizedale]

Hello,

Is there any company, anywhere in the world that can provide us with Bode Plots for an SMPS Feedback loop if we send them our schematics and the specification to which the SMPS is intended.?

I kind of doubt that there are companies that specialize in that, but there are companies like Venable Industries that make instruments for that purpose, or you could probably contract it out to a general engineering firm.

It's really not hard to do yourself. Venable has tech notes that pretty much describe exactly how it's done.

Yes, i appreciate that i can actually measure it using a frequency analyser.....but they cost $15,000.

I mean it's pretty simple with a digital oscilloscope and a simple function generator. Their first app note says how. The stuff they sell just makes it a lot easier, and maybe more accurate.
