3.9.3 Data Logging
Measured data from the LDC10xxEVM can be saved to a text file by using the Logging features, which
are located on the bottom of the main GUI window.
Figure 3-11. Data Logging
The data is saved in an ASCII text file which contains the time of data capture, the R
P
measurement, the
inductance measurement, and the raw inductance data. Data can be logged either as a single
measurement or as a continuous stream of data. To save a single measurement, set the middle button to
"Single"; if a continuous log is desired, change the setting to "Continuous". Once the mode is set, press
the "Log Data" button to save the file. A file save dialogue will open asking for the file name. It is
recommended to add ".txt" to the end of the filename if a text editor is to be used to analyze the data, or
use an extension of ".csv" if a spreadsheet program is to be used. When the Logging save mode is
continuous, the GUI will continuously save the data from the LDC10xxEVM; to stop the data saving, press
the "Log Data" button a second time.
3.10 Using a Custom Sensor
The coil plus capacitor portion of the LDC10xx Evaluation Module is perforated so that it can be snapped
off and replaced with a custom LC tank.
