You mean expected power consumption at each frequency? If yes, I think the easiest way is to plot the impedance curve by using a series resistance and my impedance viewer app, export this impedance data to excel, and calculate power from there.

It has been a while. I am back in the power supply mode. When we last spoke I was working with version 0.6.1b. I just installed your version 0.6.2b RC4. Could you tell me some of the changes in this latest version. I have a 2208B USB Pico Scope. Thanks / Charles
Thank you for the feedback, Hans.Hans Polak wrote: ↑Tue May 14, 2019 6:47 pmHi Aaron,
Thank you for the wonderful job you did with FRA4PS.
The more I use it, the more I like it, however concerning noise suppression I have a few questions.
With my 5243B I already use the "noise reject" option which was already a big step forward.
1) I can also choose a "noise reject bandwidth" although results with 100Hz are sometines better as with 10Hz, something that I cannot understand so well.
2) Then there is a "low noise oversampling" whose function is not at all clear, just as "noise reject timebase" and the "purity lower limit".
Maybe it's all to be found in your source code, but that's not exactly my beer.
To get the lowest possible noise in my images, I would be very grateful if you could give any further detail information on these adjustable parameters.
Kindest Regards,
Hans

I have a PICOSCOPE 5444B and 2207B, FRA works like a charm on the 2207B but limited to 1Mhz. Can this limit be lifted ? what are the limiting factors ? I am sorry for my ignorance, i am new here .
I tried with FRA with my PICO 5444B but i get error : Error: Unable to initialize device with serial number FX923/063.
Is the max frequency limit going to increase with 5000 series ?
Kudos for the tool!
Thanks
Regards
Kiran Kanchi.

again me with a question for improvement.
I am testing my 0.1 .. 10 Hz Low Noise amplifiers with a PS5444A.
When I try this frequency range with 24 steps/decade I get several
duplicate frequencies. Obviously the minimum resolution of the PS5444A is 0.04 Hz from frequency step to frequency step.
Would it be possible to skip the duplicate steps in the low frequency range?
Besides a more beautiful diagram without dents, this would also speed up the calculation.
with best regards
Andreas
