How Does It Compare with Other JLab Amplifier Trainers?
| Model | Amplifier stage | Studies | Supply and build |
|---|---|---|---|
| This trainer (EL-DSO-10332) | Common base and common emitter | Frequency response, gain, bandwidth, input and output impedance, effect of feedback | Built-in +12 V DC regulated supply; Bakelite front panel |
| Study of Transistor Amplifier Circuits (CB, CE and CC kit) | Common base, common emitter and common collector | Frequency response, input and output impedance, effect of negative feedback | Components on the front panel with terminals; 8 x 6 x 3 inch unit |
| Two Stage RC Coupled Transistor Amplifier | Two RC-coupled stages | Overload characteristics, frequency response of each stage and the cascade, input and output impedance | Built-in −12 V DC IC-regulated supply; two PNP transistors |
| Emitter Follower CC | Common collector (emitter follower) | Voltage gain, input impedance, output impedance | Built-in +9 V DC IC-regulated supply |
Choose this trainer for gain, bandwidth and impedance measurements on common base and common emitter amplifiers from its own +12 V supply. The two-stage RC coupled amplifier is the one for cascade-stage work, and the emitter follower board covers the common collector stage.
What Is the Transistor Amplifier Trainer Used For?
A common emitter amplifier gives both voltage and current gain with the output inverted, while a common base amplifier has a low input impedance and is used where wide bandwidth matters. The frequency response is plotted by applying a sine-wave signal over a range of frequencies and recording the output; the bandwidth lies between the frequencies at which the gain falls 3 dB below its mid-band value. Negative feedback lowers the gain but steadies it and widens the bandwidth, and it also changes the input and output impedances — effects students measure on this trainer in analog electronics practicals for diploma, B.Sc. and engineering courses.
Frequently Asked Questions
Is a signal generator included?
No. The standard accessories are a power cord, patch cords and an instruction manual; JLab’s function generators are separate items.
How does it differ from the other Study of Transistor Amplifier Circuits kit?
The other kit with this name is an 8 x 6 x 3 inch unit covering common base, common emitter and common collector amplifiers. This trainer has a 300 x 220 mm Bakelite front panel and its own +12 V DC regulated supply.
What mains supply does it need, and how big is it?
It runs on 230 V AC ±10% at 50 Hz, measures 330 x 225 x 75 mm and weighs about 2.0 kg.
What should an export enquiry include?
Send the quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs, and a tender reference if there is one.
Who manufactures this amplifier trainer?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The trainer is produced at JLab’s own works and not bought from a trader, so colleges, polytechnics, dealers and importers order straight from the maker. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 as a manufacturing enterprise. JLab exports worldwide and ships to buyers in every region — for example Slovenia in Southern Europe, the Netherlands in Western Europe, Egypt in North Africa, Hong Kong in East Asia and Oman in the Middle East. Tender buyers can use the JLab lab tenders page.
