TERMINOLOGY

Total System Accuracy

The AD5934 can accurately measure a range of impedance

values to less than 0.5% of the correct impedance value for

supply voltages between 2.7 V to 5.5 V.

Spurious-Free Dynamic Range

(SFDR)

Along with the frequency of interest, harmonics of the

fundamental frequency and images of these frequencies are

present at the output of a DDS device. The spurious-free

dynamic range refers to the largest spur or harmonic present in

the band of interest. The wideband SFDR gives the magnitude

of the largest harmonic or spur relative to the magnitude of the

fundamental frequency in the 0 to Nyquist bandwidth. The

narrow-band SFDR gives the attenuation of the largest spur

or harmonic in a bandwidth of ±200 kHz, about the

fundamental frequency.

Signal-to-Noise Ratio (SNR)

SNR is the ratio of the rms value of the measured output signal

to the rms sum of all other spectral components below the

Nyquist frequency. The value for SNR is expressed in decibels.

Total Harmonic Distortion

(THD)

THD is the ratio of the rms sum of harmonics to the

fundamental, where V1 is the rms amplitude of the

fundamental and V2, V3, V4, V5, and V6 are the rms

amplitudes of the second through the sixth harmonics.

For the AD5934, THD is defined as
