 [email protected] There is a clear difference in the spectrum and delay in the pulse in the time domain. Here again
the ABS sample is shown in white and the reference air measurement shown in red. If you click
clear comparison graphs it will clear the loaded signal and spectra to compare and shows the
last scan which is in white line.
Note: For convenience one can scan the sample first and store the data and do a reference
measurement in air next to show the reference in white line as last scan. The data for the
samples are then loaded using COMPARE from the stored data and shown in color such
as red.
Running FAST SCAN
The fast scan option uses a sine wave generator with position voltage ranging from -1.5 V to 1.5
V and frequency of 1 Hz. The Fast scan acquires a waveform every 500 ms using this setting.
The sine wave generator that drives the shaker servo motor can be increased to 20 Hz.
