WEEK 13

Objective:

• To measure the value  of IV characteristic using labView.

Activity:

• Continue to construct the labView block diagram.
• Continue solve the problem with the circuit and labVIEW and DAQcard

This project will be used variable resistor to make the load increase. The value of variable resistor used is 1kΩ. from the variable resistor, can see there is a change when the value is increase. All this change will be show and discuss below.

 labVIEW block diagram

           The specification of the DAQ card (SBC-68) are provide in the laboratory is The Maximum Voltage can support by DAQ card only 10V. Need Voltage divider (V_D) circuit to cut the value output value into half. The current part, DAQ card cannot measure the current directly. Also need external circuit (current divider, I_D) to measure the current. By using ohm law’s, the current can be calculated when there is a voltage and resistor (V=IR). 

In conclusion, the objective of this work didn't achieve because of the IV graph cannot meet the specification. the graph show that the output in inverse output.
