AG-253

Audio Signal Generator With Sync Oscilla AG-253

---

Outline

The AG-253 is a wideband low-frequency signal generator capable of producing low-distortion sine waves and square waves. The oscillation frequency ranges from 10 Hz to 1 MHz? the distortion is held to 0.004% (typical). and the AG-253 features an external sync function? a high-power output to 10Vrms (open circuit)? accurate voltage settings by means of a 10 dB-per-step attenuator. and an easy-to-use frequency setting dial? making it extremely versatile and easy to use.

Features

●Wide Frequency Range The signal generation frequency is 10 Hz to 1 MHz, the entire span covered in 5 ranges. In addition, a large, single-scaled dial is used for easy frequency settings. ●Flat Output Voltage Over the frequency range from 30 Hz to 50 kHz, the output voltage deviation is held to ±0.2 dB, and to ±0.5 dB over the entire frequency range. ●Low Distortion In the audio band (200 Hz to 20 kHz), the distortion is 0.008% or lower, and the actual measured value is 0.004% at 1 kHz. ●Synchronizing to External Signals The AG-253 can be synchronized to an external signal, enabling its use as a synchronized audio signal generator. ●Sine and Square Wave Outputs Output is possible of low-distortion sine waves or square waves having excellent rise time characteristics. ●10 dB-Step Attenuator The output voltage can be varied continuously from 0 to -50 dB using a 10 dB-per-step attenuator and a fine adjustment. ●SPECIFICATIONS SPECIFICATIONS Frequency range 10Hz to 1MHz (5 ranges) ×1 ranges 10Hz to 100Hz ×10 ranges 100Hz to 1kHz ×100 ranges 1kHz to 10kHz ×1k ranges 10kHz to 100kHz ×10k ranges 100kHz to 1MHz Frequency accuracy ± (3% 1Hz) Sinewave characteristics   Output voltage 5Vrms or more (at 600Ω load) Output voltage deviation 30Hz to 50kHz? ±0.2dB 10Hz to 1MHz? ±0.5dB Distortion characteristics 1kHz Typ 0.004% (at ×100 range) 200Hz to 20kHz 0.008% or less 20Hz to 100kHz 0.04% or less (100kHz :at ×1k range) 10Hz to 1MHz 1.5% or less Squarewave characteristics   Output voltage 10Vp-p ( at 600Ω load) Rise and fall time 200ns max (maximum output) Duty ratio Within 48:52 (at 1kHz? maximum output) External sync characteristics   Synchronous range ±1%/Vrms or more Maximum input voltage 15V (DC ACpeak) Input impedance Approx. 100kΩ Output   Output attenuator 0dB? -10dB? -20dB? -30dB? -40dB? -50dB (6 steps) (at 600Ω load? accuracy: ±1dB) Output impedance Approx. 600Ω Temperature/humidity for operation 0°C to 40°C　RH85% Temperature/humidity for characteristics in spec. 10°C to 35°C　RH85% Power source 100/120/220 AC? ±10%? 216 to 250V? 50/60Hz?  Power consumption Approx. 48W Case dimensions 128 (W)×190 (H)×285 (D) mm Maximum dimensions 128 (W)×210 (H)×326 (D) mm Weight Approx. 3.2kg Accessories Instruction manual (1)?  accessory cable (model: CA-48P)(1)?  power cord (1)
