WinDaq Add-on FFT

Operation

• Multiple FFT sizes: 1024, 2048, 4096,  8192, 16384 and 32768. 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
• For FFT size of 16384, up to 3 channels can be enabled in Windaq
• For FFT size of 32768, only 1 channels can be enabled in Windaq
• Three scaling options for the frequency axis, Standard, Logarithmic and Full-fit
• While acquiring spectrum, you may
  • click and hold the left mouse button to drag the waveform up and down
  • double-click the left or right mouse button to change the scaling of the waveform
  • adjust the Analog oscilloscope-like persistence control to study the trend of the spectrum
  • click and hold the right mouse button to enable a vertical cursor to exam to the waveform
• Once you stop the live frequency display, you may
  • click and hold the left mouse button on the chart to enable a vertical cursor and drag it around to study the spectrum
  • click and hold the right mouse button on the chart to enable a cross hair and drag it around to study the spectrum
