Jlab Export is a leading DSB and SSB AM Receiver Trainer Manufacturer,and suppliers in India
DSB and SSB AM Receiver Trainer (code EL-CT-1511) is a radio receiver trainer on which students study the reception and detection of double sideband (DSB) and single sideband (SSB) amplitude modulated signals, picked up through a telescopic antenna or fed in by cable. It tunes from 980 kHz to 1650 kHz. Jain Laboratory Instruments Pvt Ltd, trading as JLab, produces the trainer in Ambala, India.

What Is the AM Receiver Trainer Used For?
It is used in the analog communication lab of electronics and communication engineering degree and diploma courses to show how a radio receiver works, stage by stage. In a superheterodyne receiver such as this one, the mixer and local oscillator convert the tuned signal to a fixed intermediate frequency — 455 kHz here — so that most of the gain and selectivity can be provided at a single frequency. A diode detector recovers the audio from DSB signals, while SSB needs the product detector, which beats the signal against the 455 kHz crystal beat frequency oscillator to restore the audio; the output audio amplifier then drives the loudspeaker.
What to Specify When Ordering
- Quantity — the number of receiver trainers for the lab.
- Transmitting side — the DSB and SSB AM Transmitter Trainer is a separate item that can be added to the same enquiry when the practicals also cover transmission.
- Mains supply — the trainer is built for 230 V AC, 50 Hz; check that this matches the supply at the place of installation.
Frequently Asked Questions
What does AGC do in this receiver?
Automatic gain control uses the output of the envelope detector to adjust the gain of the receiver, so the audio level stays more even as the incoming signal becomes stronger or weaker.
What is an image frequency?
It is an unwanted signal lying twice the intermediate frequency away from the wanted station, which can also mix down to the IF and be heard. Studying image frequencies shows why the tuned circuits ahead of the mixer matter.
What do sensitivity, selectivity and fidelity mean?
Sensitivity is how weak a signal the receiver can pick up and still give usable output; selectivity is how well it separates the wanted station from its neighbours; fidelity is how faithfully it reproduces the original audio.
How many switched faults and test points are there?
There are 8 switched faults and 50 test points. Switching in a fault gives students a realistic problem to trace, and the test points let them check the signal at different points of the circuit with an oscilloscope.
How does it differ from the DSB and SSB AM Transmitter Trainer?
The transmitter trainer generates DSB and SSB AM signals and sends them through a gain-adjustable output amplifier to an antenna or cable. This trainer covers the receiving side, from the RF amplifier and mixer through detection to the loudspeaker.
What else is needed for the experiments?
A 20 MHz cathode ray oscilloscope, which is a separate item, for observing the waveforms. JLab’s Dual Trace Oscilloscope, linked below, can go on the same enquiry.
What should an export enquiry contain?
Please give the number of trainers, the destination country with the port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs, and a tender reference where one applies.
Who manufactures the receiver trainer?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of communication trainers, electronics lab equipment and other teaching apparatus, incorporated in 2017 and operating from Hargolal Road, Ambala, Haryana. This receiver trainer is built in JLab’s own works instead of being bought from a trader, so engineering colleges, training institutes, dealers and importers buy straight from the maker and can return to it for repeat orders and spares. JLab exports worldwide and ships to buyers in every region — for example Japan in East Asia, Tajikistan in Central Asia, Paraguay in South America, Tanzania in East Africa and Iraq in the Middle East. Tender information is on the JLab lab tenders page.
