Ok lets see if I did this right.
Setup: Signal generator probe at 1x through 0.01uF cap at tp17 ch2 set probe at 10x at cap/tp17 ch1 set probe at 10x at tp20 Scope set to 1x for both channels Signal generator set to 1v at 11.996MHZ
Measurements: Ch2 measured 6mv p-p * 10 = 60mv being generated Ch1 measured 5mv p-p * 10 = 50mv out of filter at 2khz frequency measured for approximately ~-1db loss
Does that seem about right?
(Its hard to adjust my frequency generator for best signal once set once set it can only change easily in 10k hz increments with the knob - I tried adjust a bit manually entering and that seemed to be where I get the best tone)
