  • Sine Sweep mode with linear or logarithmic sweep curves
  • Multiple waveform generators: Sine, Square Wave, Needle Pulse, and noise
  • Anti-aliased versions of Square and Needle Pulse waveforms
  • Needle Pulse unipolar impulse waveform for polarity and phase analysis
  • Decorrelated left/right channels for noise waveforms
  • Adjustable output level with 18 dB dim button
  • Real-time frequency display during sweep operations
