This saves the sweep data to a data file located in the directory
of you choice. You can access this file content by using Notepad
or Microsoft Excel to plot the data. Each file contains a single
column of data. Each data entry corresponds to each single
sweep point so, if you program 511 point as the value for the
number of increments, the array contains a single column of
data with 511 data points, starting at the start frequency and
ending at stop frequency value, which is determined by
Start frequency
+ (
number of increments
×
delta frequency
)
The
impedance profile with frequency
appears after the sweep
finishes. This shows how the impedance of the network under
analysis varies across the programmed frequency range. To view
how the relative phase across the network under analysis varies,
click
relative phase vs. frequency
. The plot in Figure 17
appears. Click

to display the plot.
The relative phase takes into account the phase introduced
through the entire signal path, that is, the phase through the
output amplifiers, transimpedance amplifiers, along with the
phase through the impedance under analysis connected
between VOUT and VIN (Pin 6 and Pin 5 of the AD5933).

and expand this
directory root (Figure 19). When the AD5933 hardware is
correctly installed, each time you plug the USB cable into the
evaluation board, the items under the
Universal Serial Bus
Controllers
root are refreshed. This indicates that the AD5933
is present each time the evaluation board USB cable is plugged
in correctly. It is subsequently refreshed when the USB cable is
