file - optional saved scan file to load

Main Window

  • Start - Scan start frequency
  • Stop - Scan stop frequency
  • Dwell - Sampling time spent on each step
  • FFT Size - FFT size, greater values result in higher analysis precision (with higher sizes dwell should be increased)
  • Continuous update - Update the display on each step (caution only use with small scans and low dwell times)
  • Grid - Show a grid on the scan

File Menu

  • Open... - Open a saved scan
  • Save As... - Save a scan
  • Export... - Export a scan to a CSV file

Scan Menu

  • Start - Start a scan

View Menu

Tools Menu

  • Compare - Compare two previously saved scans
  • Auto Calibration - Perform a crude calibration of the dongle to a known signal (this should be a continuous, unwavering signal)
