5MHz Low Cost DDS Function Generator

The DFG 2000 series LOW COST function generators with maximum frequency of 5MHz, 10MHz and 20MHz were designed based on Direct Digital Synthesis (DDS) technology providing flexible performance and system features for basic scientific and industrial requirements. These models are equipped with 8 bit resolution, 100MSa/s sampling rate, 1024 pts memory length and 32 built in waveforms for various waveforms for different needs.

The DFG 2000 series have additional functions of multiple modulations of FM, FSK, ASK and PSK, 200MHz external frequency counter, 40 sets memories and multiple protections. Low cost, stable output frequency, high accuracy and low distortion make DFG 2000 series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications.

Features:

  • 2 output channels
  • Direct Digital Synthesis technology (DDS)
  • Min. output amplitude 1mV (50Ω) with good stability
  • Sampling rate 100MSa/s, vertical resolution 8 bits and waveform length 1024 points
  • 32 built-in waveforms
  • 40 sets save and recall for panel settings
  • Modulations: FM, FSK, ASK, PSK
  • Frequency sweep, amplitude sweep, burst and TTL output functions
  • Over voltage, over current, short circuit and reverse voltage protections
  • High speed rotary dial and keypad input
  • Standard 200MHz external frequency counter
  • RS-232 interface for PC remote control
  • RS232 cable and RS232 to USB cable provided
