I just came across this.
So, it looks like the curve tracer graphs I current versus V voltage (with the voltage varying across time).
With an oscilloscope, my understanding is that it only graphs (displays) voltage over time.
Is it possible to somehow use it in a tracer mode?
For example, if you indirectly measure current by using voltage (I think that's how an Ammeter works right?) and introduce a varying voltage by another means, you can then get the data from Channel 1 for the input voltage, and Channel 2 as the indirect current measure (also voltage).
I guess the challenge is to graph the two against each other; I don't have an oscilloscope but wonder if the captured data can be downloaded to a computer and graphed there using a spreadsheet or maybe a basic C program to parse the data?
