Hi all, I am making a frequency mixer to add together channels of an amplifier I have at 52.892kHz. I am attaching a picture of the schematic and the physical circuit I made along with the output on the oscilloscope I am measuring. Instead of the three outputs shown in the schematic, I am just using one, and same for the five inputs I am just testing with one right now. Here are the pictures and I wanted to know why the oscilloscope image is A) much less than the input voltage of 10Vp-p and B) not a clean sine wave, but is flat on the top peaks. Thank you guys for your help and hope to hear back soon!
