Voltage Controlled Oscillator (V.C.O.) Trainer with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12311
Indian Lab Suppliers supplies the Voltage Controlled Oscillator (V.C.O.) Trainer with Power Supply (Product ID: 12311) as part of its electronics engineering lab equipment range. It builds several voltage-controlled oscillator circuits around a CMOS phase-locked loop IC.
Quick Answer
The VCO section of a CMOS PLL IC, with a quad 2-input NAND Schmitt-trigger IC, two potentiometers and two diodes, is wired in six ways: a constant-frequency oscillator, a wide-range VCO from near zero to above 1.5 kHz, a wide-range VCO fully variable down to zero, a restricted-range VCO, a universal clock or square-wave generator, and an FSK generator. In each case students vary the control voltage and watch the output frequency follow it on a 20 MHz CRO (not included). The board runs from an internal 9 V DC, 50 mA IC-regulated supply. Please confirm the oscilloscope connection arrangement at quotation.
