What Is the BJT Amplifiers and Emitter Follower Trainer Used For?
In a multistage amplifier the output of one transistor stage drives the next, so the overall gain builds up stage by stage, while an emitter follower (common-collector stage) has a voltage gain just below one, a high input impedance and a low output impedance, which is why it is used as a buffer. With the built-in generator, students drive these circuits at a chosen frequency and amplitude in analog electronics practicals for diploma, BSc and engineering courses.
Frequently Asked Questions
What signal source is built into the trainer?
A sine-wave generator covering 10 Hz to 100 kHz within ±10%, with an output amplitude adjustable from 0 to 5 Vpp.
What supplies does it need and provide?
It runs on 230 V ±10%, 50 Hz mains and is protected by a 500 mA slow-blow fuse. The in-built DC supply provides +12 V and +5 V for the circuits.
What information is needed for an export quotation?
Give the number of trainers, the destination country and port or city, the delivery terms you prefer such as FOB or CIF, any packing or labelling needs, and a tender reference if there is one.
Who manufactures this trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) builds it in Ambala, Haryana, India, and supplies it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a manufacturer of electronics trainers and laboratory equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is built in-house rather than bought from a trader, so colleges, dealers and importers get it direct from the maker, and repeat orders come from the same works. JLab exports worldwide and ships to buyers in every region — for example Australia in Oceania, Indonesia in Southeast Asia, Botswana in Southern Africa, Bangladesh in South Asia and Taiwan in East Asia. See the JLab lab tenders page for tender details.
