Leo, Thanks for the IFR/Aeroflex/Marconi 2401 suggestion, I looked at the data sheet and it might be a good alternative to watch for. I REALLY like the "closed box" calibration feature. I was suspicious of the E44xx series but never used or tested one, I had some hope that like other HP/Agilent instruments, they might be a lot better than what's on the spec sheet. Thanks, Don

I have tested a few units at 1GHz and the results were within 1-2dB from the datasheet, so have a look there. Don't even bother with -A/D models. If you are looking for HP 8664A/8644B class performance, have a look at IFR/Aeroflex/Marconi 2041 and 2042. Yes, they sometimes can be had for $1000.
