If your powersupply is not very high quality, you are almost certain to create a ground-loop through the power-cords of the power-supply and the spectrum analyzer. That's why batteries are such a good thing: they don't offer a path for ground loops. If you have a isolating transformer, you can try that in the signal cable between the oscilloscope and the PRS10, but it's not as good as running off batteries. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
