Start the generator, either by clicking the start icon in the window's toolbar, or by selecting Start Generator from the Control menu (or by typing Command-R).Go ahead and save the project now, if you like.Click the "On" check box in the Pseudorandom Noise section to enable the noise generator.If you selected 6000 spectral lines in step 11, select a sequence length of 12000 samples. If the right sequence length isn't available, choose a different FFT length in the FFT Analyzer to make the two match. In the Pseudorandom Noise section, at the bottom of the Signal Generator window, select a sequence length that is equal to the FFT Length (twice the number of spectral lines chosen for the FFT Analyzer, if guardbanding is turned off).
SIGNALSCOPE TUTORIAL MAC OS X
(Audio MIDI Setup is included with Mac OS X in the /Applications/Utilities/ folder.) If your device does not have both input and output channels, you will need to select one that does, or use the Aggregate Device Editor in the Audio MIDI Setup application to create one. Select your device from both the Input Device and Output Device popup menus in the project window.Make sure the nominal sample rate is set high enough to capture the desired frequency range.This will display the device's properties in the lower portion of the window. In the device table, at the top of the window. In the Device IO Setup window, click on the name of the device you would like to measure.Click the Device IO button in the project window's toolbar to open up the Device IO Setup window.Create a new project, if one was not created automatically when the program launched.
SIGNALSCOPE TUTORIAL PATCH
It is important to keep in mind that what will be measured in this tutorial is actually the combined frequency response of the input channel, the output channel, and even the patch cable between them. Figures 1 and 2 demonstrate the connections using an Echo Indigo io PCMCIA card interface and an Echo AudioFire4 FireWire interface, respectively. Using a patch cable that is appropriate for the device you are using, connect one or more outputs of the device to one or more inputs of the same device.Connect your device to your Mac (if necessary, you may want to consult your device's user guide or owner's manual).The following steps apply directly to audio devices that have both input and output channels, and it should be remembered that the measured frequency response will include the combined frequency responses of input and output channels.
