This document introduces the GF 265 model of 81 GÉNÉRATEUR DE FONCTIONS, which has a frequency range of 0.18Hz - 5MHz, very high frequency accuracy (0.005%), and very high sine quality (distortion <0.1%). It supports internal or external AM, FM, FSK, and PSK modulation schemes, internal linear or logarithmic sweep, and external frequency meter from 0.8Hz to 100MHz. It also has storage for 14 setups and parameters, 50Ω and TTL output protected up to ±60V, adjustable duty cycle (10% to 90%), and offset independent of the attenuator.
The GF 265 is a direct‑digital‑synthesis function generator offering a wide frequency range from 0.186 Hz up to 5 MHz. It delivers high‑precision sine waves with distortion below 0.15 % and supports AM, FM, FSK and PSK modulation, both internally and via external sources.
The instrument features linear or logarithmic sweep, external frequency measurement from 0.8 Hz to 100 MHz, and memory for 14 user‑defined setups. Outputs include a 50 Ω protected line capable of 20 V peak‑to‑peak, with short‑circuit protection up to +60 V. Control is provided through an RS‑232 9‑pin SUB‑D connector, and the unit complies with EN safety and EMC standards. This manual is written in French.
