Use Agilent 33220A signal generator to supply sine to full wave rectifier ?
(1/1)
electronic_guy:
Hi,

I'm trying to generate a full wave rectification signal out of a rectifier bridge made up of 4x 1N5819 diodes. Instead of using transformer i tried to input sine from signal generator. But the output waveform looks like a half wave rectifier. I checked the ground lead of the BNC output from signal generator and it doesn't show any sine wave going back to signal generator. I might be having a huge misunderstanding here. That's why i need some help with an explanation as to why signal generator output is not the same as transformer output.
Is there a way to simulate a transformer output with a signal generator ?

Thank you.

Ground problem?  The generator and the scope grounds.

Yes, draw a schematic of the four diodes in a bridge rectifier. Draw a connecting line from one side of the input to one side of the output to represent the path through the grounds of the generator output and the scope input.  Then, "Doh" time.

Look at the DC offset from the 33220A and make sure it is 0
