Staircase Generator with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12308
Indian Lab Suppliers supplies the Staircase Generator with Power Supply (Product ID: 12308) as part of its electronics engineering lab equipment range. It generates a staircase waveform with transistor switches and resets it with a unijunction transistor.
Quick Answer
Each pulse from an external pulse generator adds a fixed step of charge to a capacitor through an NPN and a PNP transistor stage, so the capacitor voltage climbs in equal steps. When it reaches the UJT’s peak-point voltage the UJT fires and discharges the capacitor, and the staircase starts again. A potentiometer sets the division ratio, the number of steps per cycle, which makes the circuit a simple pulse counter or frequency divider. The board runs from an internal 12 V DC, 30 mA supply; a pulse generator and a dual-trace 20 MHz CRO are needed. Please confirm the oscilloscope connection arrangement at quotation.
