Spectrogram II (ID=7018)

This is the second generation the original Spectrogram Windaq add-on based on a more powerful commercial FFT module:

• Multiple FFT sizes: 1024, 2048, 4096 and 8192
  • Due to Windaq's memory allocation approach, the following rule should be observed if you wish to use this add-on:
    • For FFT size of 1024, up to 58 channels can be enabled in Windaq
    • For FFT size of 2048, up to 29 channels can be enabled in Windaq
    • For FFT size of 4096, up to 15 channels can be enabled in Windaq
    • For FFT size of 8192, up to 7 channels can be enabled in Windaq
• True full ADC resolution . No more need for the Dynamic Amplifier option available in the first generation of Spectrogram
• Multiple Spectrograms can be enabled for different channels under Windaq
• Channel number is a 0-based index to Windaq's scanlist. For example, if Windaq has channel 3,4,6,7 enabled, one can enter 0 for channel 3, 1 for channel 4, 2 for channel 6 and 3 for channel 7.
• Scalable Spectrum and waterfall during acquisition.
  • Please the mouse cursor in the top spectrum display, push down the left button on the mouse and drag the waveform up and down
  • Double-click the left and right button on the mouse to change the scaling
  • The waterfall display follows the scaling and offset of the spectrum
• Single click on AutoSet button will adjust the scale to bring a weak signal into sight immediately
• Once you stop the spectrogram, you may click on the spectrum chart to enable a cursor and drag it horizontally to study the spectrum
• You may also click on the waterfall chart to enable a crosshair to show the frequency/elapsed time  
  • The elapsed time is of approximation only since the performance of the spectrogram is based on your PC's power
• The frame of Spectrogram II is sizable, and the two charts will adjust accordingly
• Intelligent Channel Select: Highlight/Select a channel in Windaq and fire up this Windaq add-on, and it will use the selected channel as its default channel

Bonus for users with paid registration :

• CopyToClipboard button provides quick access to a copy of the waveform
• No ad-line in the charts
• No restriction on Window and FFT size 
• No run time limit
  

It provides multiple FFT sizes,  higher resolution and scalable charts. The following video demonstrate some of the new features of Spectrogram II
