As you have observed, a wider bandwidth will by definition have more noise and be more susceptible to interference. However; keeping the bandwidth, let's say at 30 kHz will reduce this effect. Given that you are finding "crossover distortion" at 5 kHz in your test set and Bruno is not at 1 kHz says more about test equipment and test environment.
As we also have observed the noise floor in Bruno's test set appears to be about 20 db lower than yours if I remember correctly.
In conclusion I will ask you once again to check your test set up and especially the Oscillator in your source equipment. Given your previous statements on earth grounding I will ask the question; Is your HP Analyzer and your Source equipment properly grounded?
