[QUOTE="ludo, post: 50392, member: 691"] Hoggage! 5 posts in a row. Disgusting! Measurements indicated results pretty close to what SPICE predicted at -6dB -20dB -40dB and -60dB, so it's certainly in the ball-park within a dB or so. I only tried the 150Hz setting you initially asked for, at which point the signal generator failed. I'm not entirely surprised, the week's been that way. The same failure (bottom half of output waveform missing) was the reason I got the generator in the first place: It was broken = cheap. So I'll have to go back in there and fix it better this time. The previous repair only lasted 6 years or so. The RMAA Hennie suggests would give you a better report than I can see squinting at the graticule lines here. I think Gert also likes it. I don't think RMAA will run here as I'm on a linux box but I've not tried yet. PM, so we can figure out how to get this thing to you. [/QUOTE]
