Having just built my first 23cm contest system I've been spending a lot of time measuring noise figure (NF), adjusting, measuring etc. Been using a BBGen+ noise source (very nice and simple to use) and a HP8561E spectrum analyser. Measuring every stage from the antenna in, to output of circulator & bpf, output of preamp, output of transverter and finally the output of the Elecraft K3.
Now I've got the bug for this (blame my contest team G3M and G5LK/P for this) I was wondering if any of the Radio Comms Analysers I'm seeing on EBay would be of help here in getting consistent results in a single setup? I've noticed the R&S CMU 200, R&S CRTU, Anritsu MT8820A etc. etc.) Or am I barking up completely the wrong tree?
