Even though the bandwidth is technically sufficient for what you are using it for, the rise time is actually crippled by the bandwidth.Last edited: Mar 23, 2017

Do you have a scope? -
(Or their eyes) were incapable of seeing. prime example is this guy he thought he had it perfect until it was exposed on a tuned bench. You can actually see the intermodulation distortion highlighted in the waveform. Maybe it's not the bench that's the problem maybe it's the technician that doesn't understand how to see what he's looking at.
Being able to see a problem is only half of the equation. I wouldn't have a clue how to solve the problem.Last edited: Mar 23, 2017

What the hell is a tuned bench?
rabbiporkchop Thanks this. -
to render inductance a moot point and maintains 50 ohms at all points throughout the bench. Remember phase shift Alters what you see and if what you see isn't accurate then your adjustments won't be either. Eliminating phase shift eliminates all error from your bench, but only at a single frequency.
From page 17 of the bird 43 manual:
