EVAL-AD5940 Evaluation Kit User Guide
1. Plug the AD5940ARDZ
Arduino connectors.
2. Plug the AD5940-BioElectric
the AD5940ARDZ board.
3. Plug the AD5940 impedance test board into the microUSB
port on the AD5940-BioElectric
as in Figure 25.

Description
Frequency at which voltage is applied and measurement is taken.
Electrode where current is applied.
Daughter card that is attached to the
measurements.
Oversampling rate of the SINC filter applied to the response current data.
Resistor value in the feedback loop of the transimpedance amplifier
(depends on the maximum current range)
External resistor used for calibration of internal R
Level of the discrete Fourier transform applied to the data.
Selects whether the data is filtered through a Hanning window or not.
Resistance that is being measured.
4. Select the desired resistor value on the impedance test
board using the switches on the S2 and S3 banks.
5. Ensure the
board's microUSB port.
6. Open the SensorPal GUI and ensure the correct COM port
is selected.
7. Under the Bio-Electric Techniques section in the tool belt,
drag the Electrodermal Activity measurement into the
work area. Delete any other existing measurements in the
work area by hovering over the measurement and pressing
the trash bin icon in the bottom right corner.
8. Click the Electrodermal Activity measurement to highlight it
and view the configurable parameters beneath. The
electrodermal activity parameters are shown in Table 3.
