Scaling of output string from E4443A

Question asked by PontiacBob on Sep 7, 2010
Latest reply on Oct 11, 2010 by tabbott
I am a first time user of the E4443A and GPIB programming. When performing a spectrum measurement with a 750.123MHz input signal the result string is +7.5012300000000000E+00. How do I scale the output string? I will be making various measuements of my device from 40MHz to 1200MHz so I would like a proper technique.

Here is my command string:

E4443A instrument catalog "SA,PNOISE
E4443A ID Agilent Technologies, E4443A, MY44300377, A.09.1
E4443A instrument selection S
E4443A system options "1DS,226,266
E4443A configuration "SANalyzer
