4 - EDITING WITH DSX

MLSSA:

In order to obtain the ASCII file of a frequency response on MLSSA after measure, go to Transfer
Function Magnitude and apply some smooth to the graphic. Once the screen shows this, go to Transfer,
Export, Bode, and choose the phase (normally Actual-phase). Select a resolution of 1/6 of octave and
asign a name to the text file that will be created. It will looks like the following:

"Transfer Function Bode Plot - dB volts/volts (eq)"
      "Hz"  "Mag (dB)"       "deg"
  18.42571,   8.800242,    1.53268
  36.85141,   12.55392,   -120.637
  55.27712,   9.681987,  -62.79101
  73.70283,    11.5648,   123.8057

AUDIO PRECISION:

To import measure curves from AUDIO PRECISION ( *.ADX file extension) the Arkeops Software will ask
for Frequency vs Magnitude file with the following format:

C:\Apwin\S2\Frequency Response.at2, 10/25/07 12:14:18
Gen.Freq,          Anlr.Bandpass,     ,,,,,,
Source 1,          Data 1,            ,,,,,,

22.4375,           64.0570482866,     ,,,,,,
...

...

...

Then you will be asked for the next file which contains Frequency vs Phase data as shown below:

C:\Apwin\S2\Phase.at2, 11/16/07 14:21:47
Gen.Freq,          Anlr.Phase,        ,,,,,,

...

SPECTRALAB:

From the screen called SPECTRUM click on Overlay options, You will be taken to the Overlay Management

window from where you can click on Save Overlay (*.OVL). This file it will look like the following example:
