FG085 miniDDS Function Generator

FG085 miniDDS Function Generator

Highlights of FG085

  • Standard waveforms of Sine, Square, Triangle, Ramp (up and down), and Staircase (up and down)
  • User-defined arbitrary waveforms (AWG)
  • Frequency sweeping mode [ Video ]
  • Servo test/control signals in micro-second resolution with user programmable pulse width, amplitude, and cycle
  • Set parameters with direct digit input
  • Parameter adjustment wiht setable incremental size
  • Variable duty cycle from 1% – 100% for square signal
  • Frequency (period), amplitude, and offset can be incrementally adjusted with a rotary encoder
  • Trigger input available
