Short summary

This study investigates non-ideal instrumental effects that may degrade the performance of a high-resolution infrared spectrometer. Using standard gas cell measurements, it identifies key sources of modulation loss and spectral artifacts. A simple atmospheric example is included to demonstrate how these instrumental effects can influence scientific measurements. The results improve understanding of instrumental stability and support more accurate long-term use of the spectrometer.
