Study of Blocking Oscillator with power supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12247
Indian Lab Suppliers supplies the Study of Blocking Oscillator with power supply (Product ID: 12247) as part of its electronics engineering lab equipment range. It is a training board for an astable transistor blocking oscillator, used to study its pulse waveforms, pulse width and repetition rate.
Quick Answer
On an oscilloscope, students observe the waveforms at the base and collector of the astable blocking oscillator, first without the diode and then with it connected, to see how the diode limits the voltage overshoot at switch-off. They then measure pulse width and pulse-train frequency for various combinations of R and C. The circuit uses an NPN transistor and a 9 V DC, 100 mA IC-regulated supply connected internally. A 20 MHz oscilloscope is required.
