DDS GENERATOR - A KIT FOR INDEPENDENT INSTALLATION
Producer: AVT

The signal generator, next to the universal meter and oscilloscope, is probably one of the basic measuring instruments in the workshop of every electronics. Electrical waveforms can be generated in many ways. One of the more problematic are sinusoidal waveforms. Designing and fabricating a generator with sinusoidal output requires knowledge and experience, especially if the device is to be tunable in a wide range of frequencies. Integrated generators such as ICL8038 have become a solution, but the passive components used in their applications are subject to the aging process, which affects the quality of operation. By far the best solution is to 'get' into the work of digital circuits. Presented set is just a representative of generators that use digital signal processing.

The device is particularly recommended in electronic laboratories, in measuring systems

Selected parameters:

  • range of generated frequencies: 1 Hz ... 25 MHz
  • usable frequency range 25 Hz ... 25 MHz
  • programmable tuning step: 1 ... 999999 Hz
  • frequency setting: pulse generator or numeric keypad
  • adjustable output signal: sine or triangle
  • amplitude regulation digitally in 72 steps
  • TTL digital output
  • the ability to work as a wobbler and frequency meter
  • tile dimensions:
    • generator plate 122x37mm
    • regulator board 48x34mm
  • power supply - 10Vac
  • in the set 2 printed circuit boards, LCD display (green), set of elements ( without housing ) and documentation . The full list of elements included in the kit is included in the attached pdf file.

Note : One of the pictures shows an example of the original implementation of putty with a blue display.
