 ====== DSA Acoustic Analysis ======
+Follow the guided steps below on how to set-up an Acoustic or Octave Analysis in EDM to use with Spider hardware.\\
+===== Create Test =====
+In EDM, select to create a new test. From the New Test Wizard, select the **Acoustic Analysis** test type.\\
+{{:dsa:pasted:20240521-145221.png}}
+Next, give the test a name and description.\\
+{{:dsa:pasted:20240521-145228.png}}
+Finally, select the signal types that are wanted. The options include Auto Power Spectra (APS), Tachometer (TACHO), Octave Analysis (OCT), and Sound Level Meter (SLM). You are **unable** to add more signal types to be computed once the test is created. Press **Finish** to create the test.\\

+===== Test Configuration =====
+For Acoustic Analysis, there are two unique parameters that may need to be set up, //Octave Filter// and //Sound Level Meter//. Please go here for more information on basic [[dsa:fft|FFT Analysis Parameters]].\\
+=== Octave Filter Parameters ===
+If Octave Filters are being applied, their parameters must first be set.\\
+//Octave Resolution//- Defines the octave resolution including: 1/1, 1/3, 1/6, 1/12, and 1/24.\\
+//Low/High Frequency Band//- Defines the low and high frequency of the measurement in Hz.\\
+//Average Mode//- Defines the averaging type: exponential, linear and peak hold.\\
+//Frequency Weighting//- Defines the frequency weighting including A, B, C or Z.\\
+//Time Trace Frequency//- Defines which center band frequency, overall or frequency weighted band is used to plot time traces.\\
+//Trace Update Times//- Defines the time trace display duration. Select a larger update time to create longer time trace display duration.\\

+=== Sound Level Meter (SLM) Parameters ===
+If the SLM is being used, the parameters must first be set.\\
+//Time Trace Type//- Defines the time weighting including L, Leq and LE.\\
+//Analysis Period//- Specifies the time duration for each analysis period.\\
+//Result Update Time(s)//- Defines how many times the result will be updated.\\
+//Result History//- Defines the measurement length of the result history.\\
