F.E.T. Characteristics and Amplifier Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12089
Indian Lab Suppliers supplies the F.E.T. Characteristics and Amplifier (Product ID: 12089) as part of its electronics engineering lab equipment range. It is a self-contained board for plotting FET characteristics, finding its small-signal parameters and testing it as an amplifier.
Quick Answer
Two variable DC supplies (0–20 V and 0–12 V, both 50 mA), two 3½-digit DC voltmeters (0–20 V) and a 3½-digit DC current meter (0–20 mA) are used to measure IDSS, drain characteristics at fixed VGS and transfer characteristics at fixed VDS, and to show the FET working as a voltage-variable resistor. From these curves students calculate drain resistance rd, transconductance gm and amplification factor μ at an operating point. For the amplifier part, a built-in sine oscillator (15 Hz–150 kHz in four ranges) and three decade resistance banks are used to find gain, overload behaviour, frequency response and input and output impedance. It runs on 230 V ±10%, 50 Hz mains.
