THD + N
High Resolution Generator Residual THD + N
(Normal Mode)
Residual THD+N of the high resolution generator without
the bandpass filter in place. These specifications are
baseline for nonsine-wave signals and for sine-wave
signals not generated in the low-distortion mode.
Measurements over 80 kHz BW are noise limited below –4 dBu.
Measurements over 22 kHz BW are noise limited below –10 dBu.

Residual THD + N (Low Distortion Mode)
Residual THD+N with the bandpass filter in place. These
specifications are baseline for sine waves generated in
the low-distortion mode.
Amplitudes less than –16 dBu are noise limited (22 kHz BW).
