I would like to use ADALM2000 as OSCILLOSCOPE TO plot I- V characteristics in x- Y mode. Any help /sugeestions/possibilities will be appreciated.
Do you mean something like doing this diode I/V plot:
or this transistor Ic vs Vce plot:
The M2k does not measure current directly so it requires a shunt resistor which introduces an additional voltage drop. The limited voltage resolution limits how small you can make the shunt resistor. The AD8210 current shunt monitor (from the ADALP2000 parts kit) can add a gain of 20 which can increase the range of possible current measurements and or shunt resistor values.
You can then use Scopy's Math channel functionality to convert from votls to amps, and select the math channel as an input for the X-Y plot
Thanks Adrian.. we will try out
Thanks Doug.. we will try out
we configured the maths input channel. can you please guide how to plot OF THE ATTACHED CIRCUIT V-I plot in XY MODE.
screen shots are attached. We will of course modify the maths function to current= V/R
can you please suggest /guide hpw the shunt resistor can be wired and how to display in X-Y mode. we have configured second channel as maths input as shown in the screen shop. we will modify the maths function to show current as Voltage/resistor
