Hello,<br> <br> I'm trying to pulse an LED and use the keithley to measure IV curves on a sample at the same time.&#160;<br> <br> So far I've been using a function generator to pulse the LED and the front panel on the keithley to measure IV on the DUT.<br> <br> I was wondering if its possible to independently assign voltages to the front and rear panels?<br> <br> Appreciate any help,<br> Paul
