Please don't forget that the 3458A is not just an 8.5 digit
metrological wonder, it is also a precision 16 bit 100 ksample/s
Many of the attributes of the input circuit are not there for
Poul-Henning Kamp | UNIX since Zilog Zeus 3.20
phk at FreeBSD.ORG | TCP/IP since RFC 956
FreeBSD committer | BSD since 4.3-tahoe
Never attribute to malice what can adequately be explained by incompetence.
