Outline

The AG-203D and AG-204D are low-frequency signal generators featuring sine wave output with low distortion and square wave output with good rise time characteristics. They cover the frequency range of 10 Hz to 1 MHz with no breaks??A??i and a designed for versatility??A??i with such features as external synchronization??A??i a 10 dB-per-step attenuator for accurate output voltage setting??A??i and a large dial for frequency setting. All this performance is packed into a slim??A??i compact??A??i easy-to-operate signal generator housing.

Features

●Wide Frequency Range The oscillation frequency range extends from 10 Hz to 1 MHz, covered in five continuous steps. A large, single-scale dial is used to simplify the measurement value reading (oscillation frequency setting) ●Low-Distortion, Flat Voltage Output With low distortion of below 0.1% with the AG-203D and below 0.02% with the A-204D and output voltage deviation within ±0.5 dB over the entire frequency range, these generators will find use in a broad range of applications, particularly in distortion measurements, S/N measurements and frequency response measurements. ●10 dB-Per-Step Attenuator The output voltage can be set from 0 to 50 dB in 10 dB steps using a built-in attenuator, this combining with a fine adjustment to enable the output of any desired voltage level in that range. ●Synchronizing to External Signals By synchronizing the output to an external signal through the external sync input, it is possible to output more accurate frequencies from these generators. ●Rectangular Wave Output with Good Rise Time Characteristic In addition to low-distortion sine waves, square waves with excellent rise time characteristics can be output, this is very convenient for use in the adjustment and servicing of audio equipment, and for educational experimentation in school laboratories etc. ●SPECIFICATIONS MODEL AG-203D AG-204D Frequency range 10Hz～1MHz ×1 range 　10Hz to 100Hz ×10 range 　100Hz to 1kHz ×100 range 　1kHz to 10kHz ×1k range 　10kHz to 100kHz ×10k range 　100kHz to 1MHz Frequency accuracy ±(3% 1Hz) Sinewave characteristics Output voltage 5Vrms or more (at 600Ω load) Output voltage deviation ±0.5dB (10Hz to 1MHz) Distortion factor 400Hz to 20kHz 0.1% or less 100Hz to 100kHz 0.3% or less (100Hz : at×10 range) 50Hz to 200kHz 0.5% or less 20Hz to 500kHz 1.0% or less 10Hz to 1MHz 1.5% or less 500Hz to 20kHz 0.02% or less 100Hz to 100kHz 0.05% or less (100Hz : at×10 range? 100kHz : at×1k range) 50Hz to 200kHz 0.3% or less 20Hz to 500kHz 0.5% or less 10Hz to 1MHz 1.5% or less Squarewave characteristics Output voltage 10Vp-p (600Ω load) Rise time 200ns max (at maximum output) Duty ratio Within 45:55 (at 1kHz? maximum output) External sync characteristics Synchronous range ±1%/Vrms or more Maximum input voltage 15V (DC AC peak) Input impedance Approx. 100kΩ Output characteristics Output impedance Approx. 600Ω Output attenuator 0dB? -10dB? -20dB? -30dB? -40dB? -50dB (6 steps) Output attenuator accuracy within±1dB Temperature/humidity for operation 0 to 40°C　RH85% or less Temperature/humidity for characteristics in spec. 0 to 35°C　RH85% or less Power source 100/120/220V/230V AC? ±10% 50/60Hz  Power consumption Approx. 5W Dimensions 128 (W)×190 (H)×239 (D) mm 128 (W)×190 (H)×285 (D) mm Weight Approx. 2.9kg Approx. 3.2kg Accessories Instruction manual (1)?  accessory cable (model: CA-48P)(1)?  power cord (1)
