Impedance Analyser - Export consecutive passes

[AML]

Hello

I'm new to the waveforms environment. I'm using the impedance-analyser module along with a Discovery 2 and would like to run continuous impedance analysis on samples where the impedance will change over time. Consequently, I would like to save/export the data from each consecutive sweep across my chosen frequency range (as I leave it to run). Currently, it would seem like only the most recent pass gets stored.

How could I go about saving/exporting each pass? Apologies if this is the wrong part of the forum for this question.

Kind regards

AML

Hi @AML,

I have moved your question to a more appropriate section of the forum.

Thanks,

Hi @AML

You could use a Script like this to automate analysis and export:

for(var i = 0; i < 100 & wait(1.5); i++){ // wait 1.5 seconds
    Impedance.single() // start
    if(!Impedance.wait()) throw "Stopped" // wait to finish
    print(i)
    Impedance.Export("~/Desktop/imp/"+i+".csv") // see Help/Script and Impedance/File/Export for more info
}

 

If you are interested only for measurements at a specific frequency: set Constant frequency, specify required Steps and rate using the Settle under Options (or use Averaging).
