I wonder what happens if one parameter is off - do they adjust all other parameters? My VNA will go to Agilent today or tommorow. If the frequency reference was a bit off, would they adjust every parameter in that fairly complex instrument, or just the frequency reference? I guess in principle, a change of the frequency could have any effect on everyhing. The instrument has a specified frequency range of 50 MHz to 20 GHz. If the frequency was high by 10% (exhagerated of course), the other parameters would have been tested over the range 55 MHz to 22 GHz, so really they need rechecking, as it could be out of spec at the lower limit. Like at least some others, I would prefer an instrument was adjusted to be as accurate as possible, but I'd still rather pay Agilent to cal it than some random lab. I think it does depend someone on the instrument though. I would not send a 5.5 digit DVM to agilent for cal.
