Re: HP8903B - THD measure on Phono RIAA preamplifier
Hi Chris, thanks I also think that the reverse RIAA also helps me to reduce the noise and to obtain a more realistic measure of the distortion. The HP8903B in my opinion is still an excellent audio

Re: Mixing 'n' matching S parameter test sets
That's a good point, Rainer. I don't have the phase-matched cables necessary. I did try making some up a while ago, but unfortunately they were not 'flat' all the way up to 1300Mhz. It's a lot harder

Re: Mixing 'n' matching S parameter test sets
One could do that, but it isn't preserving the 8754A as it was originally intended to be used, it is making a hybrid VNA with the automatic switching of a 8753 etc. When we bought 8754A in the 1980s,

Re: HP8903B - THD measure on Phono RIAA preamplifier
It is true that the freq response curve of RIAA standard deviates from flat, so that THD is not exactly what you think. However, RIAA preamps are typically measured that way. You could build a passive
