Hi
I need to test diode strings with a pulse generator up to Vf=20Vpp, If=200 mA with a 100 ohm load. I just have to measure I am not familiar with diode testing but I need to have a few questions answered:
A) Can I use a Arbitrary Waveform Generator whose output is 10Vpp into a 50 ohm load, 20 Vpp into an open circuit? Would the AWG be capable of supplying 200 mA? In the fixture I measure the VF of the diode string.
b) Can I make one by using a pulse generator and by using an op amp - I'm thinking of the TI THS3091 - to amplify and deliver the 200 mA pulsed to the diode string?
c) Is there a better way? I can't afford to rent the 8114A which has been recommended to me ($1k/month for 3 months).
