Modulation Domain Analysis

The system is designed to make a direct frequency measurement in comparison with an external 10 MHz frequency reference. Picotime is based on a heterodyne system using direct digital synthesizer (DDS) technology to allow measurements in the range of up to 30 MHz. The external 10 MHz reference divided by 2×107 is used to make time interval measurement each second.

Features

Key capabilities and advantages

  • View dynamic frequency changes over time
  • View residual FM and AM on up to 60 GHz carriers (CNT-90XL)
  • Follow frequency changes every 4µs in real time (every 10 ns with repetitive sampling)
  • Analyze VCO settling, PLL responses and more
  • Analyze frequency hopping, chirp radar, frequency droop to 20 GHz
  • Powerful analysis: Statistics (histogram), FFT, smoothing, ADEV and MADEV vs τ Zero dead-time measurements, detect phase jumps
