Twin-Tee Oscillator (V.V) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12157
Indian Lab Suppliers supplies the Twin-Tee Oscillator (V.V) (Product ID: 12157) as part of its electronics engineering lab equipment range. It is a vacuum-valve training board for studying an R-C oscillator whose frequency is set by a twin-T network.
Quick Answer
A valve is mounted on the panel with its base wired internally, and a band switch changes the R-C combinations of the twin-T network so the oscillation frequency can be changed in steps. The twin-T is a notch network; for the standard symmetrical form the notch lies at f = 1/(2πRC), and placed in the feedback loop it makes the amplifier oscillate close to that frequency. An external regulated power supply is required; the valve type, supply voltages and frequency range are not stated, so please confirm them at quotation.
Key Specifications
| Parameter | Detail |
|---|---|
| Active device | One valve, base fixed on panel, wired internally |
| Frequency selection | Band switch for R-C combinations |
| Experiment | Study of the twin-T oscillator |
| Connections | 4 mm terminals; stackable spring-loaded patch cords, 0.5 m |
| Also required | IC regulated power supply |
Where This Is Used
Compared with the transistor Wien bridge audio oscillator with power supply (Product ID: 12135) and Phase Shift Audio Oscillator with power supply (Product ID: 12136). Valve anode supplies are at dangerous voltages and valves run hot, so work under supervision and switch off before touching the board.
