Re: Frequency Response Analyzer with Bode Plots

HI Aaron Yes regarding the probes. My probes come with a connector that you can attach to your scope probe, after you have removed the tip and gnd lead. So you can use the scope probe to connect into that connector on your pcb. (The gnd lead picks up a lot of switching noise and makes the probed sig...

Re: Frequency Response Analyzer with Bode Plots

Thanks Aaron. Yes, agreed, the low frequency response is not usually where we're looking at primarily. Also you're right that it is +/-50mV full scale is the most sensitive setting for 3206B. I was also wondering - do you make use of the moving average filter? That increases the effective resolution...

Re: Frequency Response Analyzer with Bode Plots

Hi hexamer I did look at the 5000A series and indeed it has variable resolution, up to 16 bits. Very good Picoscope. I did note this comment at the bottom of its spec table, seen in the link below:- "** Maximum effective resolution is limited on the lowest voltage ranges: ±10 mV = 8 bits • ±20 mV = ...

Re: Frequency Response Analyzer with Bode Plots

Hi I'm using a 3206B picoscope. I've downloaded the PicoSDK and FRA software and it starts-up ok. So far so good! My goal is to measure dc/dc converter Bode plot responses. I'm thinking I need an isolation transformer. Before I invest in one, can you say how effective the 3206B is for this kind of w...
