How to measure IV- Curve of 1 Kilo Ohm using USB-202 DAQ with DASYLab 2022?

[sibtulhassansherazi]

Hi All,

Basically, I wanted to record/draw the IV Curve of the resistance (1 Kilo Ohm placed on the physical breadboard) via the Chart recorder or XY Graph of USB 202 DAQ with DASYLab 2022.

The input to one end of the resistor is the Analog Output (0 Volt to 1 Volt in 1 minute with 0.1 V step size) and the other end is grounded.

Now the question is how I can measure the current through resistance. And after measuring the current, how can I draw the IV Curve? I am confused as the Analog input of USB 202 DAQ takes voltage as input, not as current.

May I request to please assist me in this regard and tell me how I can do this?
