Just curious....
How did you obtain your references for your sweep? Was it for forward or reverse? Ive found that the probes used to sample/inject at the ports have significant differences than whats actually leaving the port of the node (especially the tilt). The new 3040's with the dir. coupled test points are much more accurate, and i regularly get less than 1.0 P/V at my first amp.
> I'm in Concord Ca., been in the west my entire time in the business. It's the same senerio with us, two amps deep but we also used the ADC amps in the beginning. They're a real pain to set up ( you have to use either a palmtop or a laptop computer ), but once you get them dialed in they hold really well, the problem with the ADC node and amp combination was that the ADC spec. was a 2.9 p/v at the first amp and it was hard to hit, when we changed to the SA nodes we were able to get the p/v down as low as .9 with the average being around 1.5, it was a big differance
