Data Sheet
AD5934
Rev. C | Page 23 of 32
Valid Real/Imaginary Data
This bit is set when data processing for the current frequency
point is finished, indicating real/imaginary data available for
reading. The bit is reset when a start frequency sweep/increment
frequency/repeat frequency DDS command is issued. In addition,
this bit is reset to 0 when a reset command is issued to the
control register.
Frequency Sweep Complete
This bit is set when data processing for the last frequency point in
the sweep is complete. This bit is reset when a start frequency
sweep command is issued to the control register. This bit is also
reset when a reset command is issued to the control register.
REAL AND IMAGINARY DATA REGISTERS (16 BITS—
REGISTER ADDRESS 0x94, REGISTER ADDRESS
0x95, REGISTER ADDRESS 0x96, REGISTER
ADDRESS 0x97)
These registers contain a digital representation of the real and
imaginary components of the impedance measured for the
current frequency point. The values are stored in 16-bit, twos
complement format. To convert this number to an actual
impedance value, the magnitude,

, must
be multiplied by an admittance/code number (called a gain
factor) to give the admittance and the result inverted to give the
impedance. The gain factor varies for each ac excitation
voltage/gain combination.
The default value upon reset: these registers are not reset at
power-up or on receipt of a reset command. Note that the data
in these registers is only valid if Bit D1 in the status register is
set, indicating that the processing at the current frequency point
is complete.
