[Sample available] Variable range 10,000 times, high precision range 1,000 times. A specification sheet of the latest data will be provided as a gift.
The product has a 30-year history! It features a voltage-controlled sine wave oscillator module utilizing state-variable filters, characterized by a wide variable range, fast response speed (within 0.1 mS), and low distortion (below 0.1%). Additionally, the frequency change in response to the control voltage can be either linear or logarithmic. The set frequency accuracy (linearity) is extremely high, within 1%. 【Features】 ■ Flat amplitude characteristics within ±0.5 dB over a range of 10,000 times ■ High-performance compact module for easy integration ■ Purely electronic design ensures long-term stability ■ Logarithmic frequency setting type with 90-degree phase-shifted output ◇◆◆◇◆━━━━━━━━━━━━━━━━━━━━━━━━━ We have included the latest data on 'distortion rate characteristics' and 'control voltage to frequency linearity errors' in our catalog. Please take this opportunity to have a look. ━━━━━━━━━━━━━━━━━━━━━━━━━◇◆◆◇◆

basic information
【Features】 ■ The main application is as a testing instrument for the frequency characteristics of all speaker systems, headphones, etc., including audio, video, and mobile. ■ High-performance circuits are miniaturized into compact modules, contributing to space reduction, cost reduction, and decreased assembly time. ■ Long-term stable operation is ensured by epoxy or silicone filling, protecting against temperature, humidity, dust, etc. (Products incorporated since the mid-1980s are still operational!) ■ Easy integration, as it is analog-based, eliminating the need for peripheral software design (it operates immediately when connected to a standard power supply of ±12V to 16V and control voltage. There is no random noise interference). ■ Wide variable range, with some models offering stability over 2,000 to more than 10,000 times, with minimal aging changes. * We mainly handle products that cover the audio frequency range, but depending on the model, the oscillation frequency can range from DC to 250 kHz. The delivery time for standard products is approximately three weeks, and we can ship immediately depending on stock availability. Many modular products can be made thinner through packaging methods, so please consult us if you require a slim and lightweight design.
