of the FRA module. The time domain information consists of the raw X
and Y sine waves. This information can be used to build a Lissajous plot,
or to evaluate the signal to noise ratio and to verify the linearity of the
cell response. The Time domain, X (AC) and Y (AC) and X resolution
and Y resolution signals are added to the data for each individual
frequency when this option is on.
Sample frequency domain: if this option is active, the frequency domain
information will be sampled and stored for the X and the Y. The
frequency domain information consists of the calculated FFT results
obtained from the measured time domain. The frequency domain
information can be used to evaluate the measured frequency
contributions. The Frequency domain, X frequency domain and Y
frequency domain signals are added to the data for each individual
frequency when this option is on.
Sample DC: if this option is active, the DC components for both the
potential and current will be sampled and stored alongside the
impedance data. The Potential (DC) and Current (DC) signals are added
to the data for each individual frequency when this option is checked.
This option is active by default.
Calculate admittance: if this option is active, the admittance values will
be calculated during the measurement (Y’, -Y”).
Note
The names defined in the External section of the FRA editor will be used to
identify the X and Y signals in the procedure editor.
Additional settings can be specified in the Advanced editor. To toggle the display
of the parameter, click the
button next to the Advanced label in the editor (see
Figure 170).
Note
The Advanced settings are predefined to an optimal value for most
measurements. Please read the following section of the manual carefully before
adjusting these settings.
