Path
Coupling
Path Coupling sets the input path for measurement of the AC or AC and DC com-
ponent of the AF signal:
AC DC component of the measured AF signal (including a possible
DC offset of the input amplifier) blocked. This ensures accurate
measurement of the AC component. The DC component, how-
ever, can not be measured.
DC Measurement of the complete AF input signal (DC plus AC com-
ponents).
Note: The path coupling has an impact on the allowed filter settings; see
section Input Path Configuration (Analyzer Configuration – Filter) on p.
4.82 f.

Distortion
Frequency
Distortion Frequency defines the reference frequency of the distortion measure-
ment. If the reference frequency is set to the fundamental frequency of the AF sig-
nal, the Distortion value corresponds to the Total Harmonic Distortion and Noise.

Generator Settings (Analyzer Configuration – Generator)
The Generator tab defines the properties of the generated AF signals. The settings can be defined in-
dependently for the two AF generators.

Default Settings
The Default Settings switch assigns default values to all settings in the Generator
tab (the default values are quoted in the command description in chapter 6 of this
manual). In addition, default switches for the two independent generators are pro-
vided.
