LXSOFTWARE FEATURES
-
Compatible with Windows Vista, Windows 7, 8, and 10
-
Mac support is also available via Parallels® or another virtualization software.
-
New Respiration Line Excursion (RLE) Tool
-
The RLE tool measures the ratio of the relevant response divided by the comparison response and produces a suggested pneumograph score. As the examiner selects a relevant question, the tool normalizes it to all other questions on the chart and displays the R/C measurement ratio.
-
New ESS Report Generator
-
Uses scores from the manual score sheet to formulate a printable report and summary conclusion paragraph to describe the test results of event-specific and multi-issue exams.
-
Report includes both a categorical result and a statistical classifier in the form of a p-value, confidence level or odds ratio, and also includes the manual scores and information about test accuracy.
-
PLE Pulse Amplitude Tool
-
A virtual sensor derived from the PPG sensor providing a visual comparison of the pulse amplitude changes in the PPG data around the question onsets.
-
EDA Design (6) EDA choices (GSR or GSC – Tilt table, detrended, and automatic)
-
Supports the LX5000 GSR or GSC modes
-
Automatic: classical high-pass filter solution to EDA signal processing. Attempts to keep the trace centered on a common baseline.
-
Manual: examiner is in charge of controlling the sensor trace via centering, sensitivity, and slope adjustments. The slope may be adjusted via a slider control under the sensor arrow.
-
Detrended: hands-off solution with extremely high correspondence with the manual EDA. Attempts to keep the trace centered on a common baseline, but the sensor trace is not permitted to dip below its corresponding sensor arrow.
