SASLab Manual


Curve window : File


Print Prints the currently visible contents of the curve window. The parameters defined on the prop-down menu Export Parameters will be applied. Optionally a caption can be input.

Save Saves the visible contents of the curve window into a WMF-graphics-file.

Copy Copies the contents of the curve window into the clipboard (WMF-format).

Export Parameters...

Data export >

Save ASCII file Saves the curve window data into an ASCII-file.

Copy ASCII file Copies the curve window data into the clipboard (ASCII-format)

Add x axis increments This option will add the x-axis increments to the ASCII data in the two above commands.

Save as .WAV file… Saves the curve window data into a .wav file.

Copy WAV file Copies the curve window data into the clipboard (WAV-Format).

Save as .ft file… Saves the curve window data into an ASCII amplitude envelope file (*.at) that can be used for subsequent synthesis purposes (for instance on the command Edit/Change volume…).

Save as .flf file… Saves the curve window data into an ASCII spectrum file (*.flf) that can be used for subsequent synthesis purposes (for instance on the command Edit/Filter/Time Domain FIR Filter… or Edit/Filter/Frequency Transformation…).

Copy cursor values The most recent values measured by the cross hair cursors will be copied into the clipboard. Additionally the measured values can be transferred to other Windows-applications by DDE (Dynamic Data Exchange) or they can be stored into an ASCII-log-file. This has to be specified with the following menu "File/DDE Parameters / Log File".

DDE Parameters / Log File...


The following menu options are only available in the real-time spectrum display mode, which can be launched from the main window menu option File > Real-time spectrum.

Start real-time spectrum Start the real-time spectrum display.

Stop real-time spectrum Stops the real-time display.

Real-time spectrum setup: The following parameters can be adjusted:

FFT length: The FFT length determines the frequency resolution of the spectrum, which is equal to the sampling frequency divided by the FFT length.
Window type: The window type determines the suppression of spectral leakage and the effective frequency resolution.
Logarithmic power spectrum: If this option is checked, the spectrum will be displayed as a logarithmic power spectrum in dB.

Sound card settings... This dialog box allows setting the sampling frequency and bit-depth. If there is more than one sound card installed, the desired device can be selected. The other parameters (Duration of recording and Perform sampling-frequency conversion) do not affect the real-time spectrum display.
