Data sheet Function generator GF5+ 5MHZ


- The GF5+ generator is both classic while preserving the didactic ergonomics of the former GF5, and modern with its digital functions such as the graphic LCD display and the DDS Technology that ensures accuracy, stability and ease of adjustment.
- Its new box with stands and power cord roller makes it more comfortable to use. It is equipped with a 10W low resistance amplifier which output can be connected directly to a speaker, an RLC circuit or Melde's vibrator. The delivered voltage remains constant for a current delivered at up to 1,1 A.
- The amplifier input is connected by default to the generator internal signal but may also be engaged by a microphone signal that we connect on the front side to a 6.35 mm jack plug.
- VCF / AM / FM input allows the continuous adjustment of the frequency by an external voltage (automatically generated by a datalogging system, for example) as well as an AM and FM modulation from an external signal.

Qu'est ce qu'un générateur DDS ?
DDS “direct digital synthesis” soit en français : “synthèse numérique directe”.

Les signaux sont générés sous une forme numérique, puis restitués à travers un convertisseur numérique / analogique, offrant une équivalence quasi parfaite de forme avec un signal analogique.
Cette technologie apporte une grande stabilité dans le temps et une grande précision des réglages, autant pour les fréquences très basses (1 mHz) que pour les fréquences élevées (5 MHz et plus).
