MAG %fs
Figure 5-29, Magnitude Output as % Full-Scale
Shows the signal magnitude, where magnitude = √((X output)
percentage of the selected full-scale sensitivity setting. Hence if the sensitivity setting
were 100 mV and a 50 mV signal were applied, regardless of the setting of the
instrument's reference phase, the display would read 50.00 %
Noise %fs
Figure 5-30, Noise Output as % Full-Scale
Shows the noise accompanying the signal, in a bandwidth defined by the setting of the
output filter time constant, where it is assumed that the noise is Gaussian. The value
is given as a percentage of the instrument's selected full-scale sensitivity setting. Note
that the displayed value will change as the time constant control is adjusted. The
instrument offers a second Noise output (discussed later in this section), expressed
directly in terms of volts or amps per root Hertz, which takes this effect into account.
