So I won the lottery and won a small contract to do some power supply design using GaN transistors, and now I need a real scope.
At previous employers, I've used Tektronix scopes for this type of development, but considering the insane price of the probes (IsoVu Isolated Probes | Tektronix), and somewhat small budget of the contract, I have to consider other methods for testing (math functions, single probe testing, etc.)
Requirements:
Minimum: 1GHz, Power Analysis features, Bode Plots (and function generator), Segmented Memory, reasonable Sample Depth (doesn't need to be too big though - this spec is a little overrated IMHO with segmented memory)
Nice to haves: MDO - I2C, CAN, High Speed Parallel Bus
Price point: Somewhat open, but I have a budget in mind.
I'm mostly looking at Keysight, Tektronix, R&S, and Lecroy. I've used Keysight and Tek scopes a lot, and am pretty familiar with their user interfaces and pros and cons. I've never used R&S and Lecroy though - so was curious to get input from others based on their experience. I've also thought about buying used - any experience here? Have folks had success negotiating lower prices or additional gear when you're spending this kind of money on a scope?
Really not interested in third-tier manufactures (Rigol, Siglent, etc), and will not consider them. I'm just not interested in hacking, buggy firmware, etc. I need professional gear.
