S/D: Indicator for the Signal-to-Distortion Ratio, in

dB. This is the ratio of the signal magnitude to the

magnitude of the first four harmonics.

S/N+D: Indicator for the Signal-to-Noise + Distor-

tion Ratio in dB. This is the ratio of the signal mag-

nitude to the magnitude of the first four harmonics

and the noise.

SNR: Indicator for the Signal-to-Noise Ratio in

dB. This is the ratio of the signal magnitude to the

magnitude of the noise (an average noise value is

included in place of the first four harmonics).

S/PN: Indicator for the Signal-to-Peak Noise Ratio

in dB. This is the ratio of the signal magnitude to

the magnitude of the highest noise component not

included in the harmonics of the signal.

#of AVG: Displays the number of FFT’s averaged

in the current display.

2.3.3 Time Domain Plots

The following indicators are associated with Time

Domain analysis (Figure 5).

COUNT: Displays current x-position of the cursor

on the time domain display. This represents the po-

sition of the code within the collected sample set.

MAGNITUDE: Displays current y-position of the

cursor on the time domain display. This represents

the actual code from the converter.

MAXIMUM: Indicator for the maximum value of

the collected data set.

MINIMUM: Indicator for the minimum value of

the collected data set.
