Failry new to multisim was hoping you guys could help me out with this
Here is what i want to do.
I have a simple 2n2222 NPN BJT
All im after is to see VBE based on a tempature and also based on the IB current
So i want IB on the y axis and VBE on the x axis. I need IB to seep between 0 and and 500uA from my current source while also changing the tempature from 25degrees C to 150 degreesC. What i should get is several plots on the same graph with showing how the VBE termins voltage changes based on the current at that time and also the tempature. AKA it should look like several diode curves at once. Im the only one using multi sim everyone else i know uses orcad and it works just fine for them. I cant get multisim to do this. Any help would be much appreciated or im going to have to resort to the dreaded orcad

Hi;
You need to use the Multisim Temperature Sweep Analysis. In the following document you can find how to configure this analysis:
