6.5.2 Spectrum Analyzer
This function yields access to a powerful spectrum analyzer allowing a 1/3-octave band and narrow
band analysis. The user can adjust the type of average (exponential or linear) and the average
time. Standard Leq and statistical results (Lx%) can be presented on the graph and exported for
reports.
The spectrum analyser function (Figure 50) is a powerful tool that offers access to a one-1/3-octave
band and narrow band spectrum analyzer of the reference input signal (IMIC or SLM, see previous
section) or to any input signal of the SmartSMS unit.

Selection of the input signal
Any SmartSMS input signal can be analyzed. To do so, select the appropriate input using the Input
Used for Measurement field.
The list of inputs always starts with the reference input. The rest of the list includes all other
available inputs on the SMS unit(s). Each SMS unit has auxiliary, active and reference connector
inputs. The number of each kind of input depends on the hardware version (see section 2).
