Product Code : EL-TAMI-1023
Jlab Export is a leading R.F. Oscillator AM and FM Manufacturer,and suppliers in India
R.F. Oscillator AM and FM (code EL-TAMI-1023) is an RF signal generator for testing radio and television sets, variable from 200 kHz to 280 MHz in seven bands on a calibrated dial. The output is modulated at 400 Hz and 1 kHz, FM modulation is switched in automatically above 50 MHz, and the output level is variable from 0 to 200 mV. It is made by Jain Laboratory Instruments Pvt Ltd (JLab) at its works in Ambala, India.

How Does It Compare with Other JLab R.F. Oscillators?
| Model | Frequency coverage | Modulation and output | Listed use |
|---|---|---|---|
| This oscillator (EL-TAMI-1023) | 200 kHz to 280 MHz in seven bands | 400 Hz and 1 kHz; FM above 50 MHz; 0 to 200 mV | Testing radio and TV sets |
| R.F. Oscillator | 100 kHz to 30 MHz in eight bands | Continuous wave or modulated; 400 Hz at 30% depth, tone also on terminals | General RF signal source |
| R.F. Oscillators | 3 MHz, dial calibrated | High output voltage | Ultrasonic and Lecher wire experiments |
Choose this model when students service both AM and FM receivers or work above 30 MHz. The R.F. Oscillator is the simpler choice for medium-wave and short-wave work and starts lower, at 100 kHz, while the 3 MHz oscillator is meant for ultrasonic experiments.
What Is the AM/FM R.F. Oscillator Used For?
In radio and TV servicing, a signal generator replaces the broadcast station: the technician injects a known, modulated signal at the aerial, mixer or IF stage and follows it through the set until the fault is found, then aligns the tuned circuits for the strongest, cleanest output. Below 50 MHz this oscillator gives an amplitude-modulated test signal with a 400 Hz or 1 kHz tone, suited to AM receivers; above 50 MHz it switches to FM modulation, covering the FM broadcast band and VHF television channels within its 280 MHz upper limit. The adjustable 0 to 200 mV output lets students start with a strong signal and reduce it to check sensitivity. It suits ITI and polytechnic radio and TV mechanic courses, engineering communication labs and B.Sc. electronics practicals; keep the output lead short and screened at higher frequencies.
What to Specify When Ordering
- Model — this AM/FM generator for radio and TV work, or the R.F. Oscillator for lower-frequency receiver experiments.
- Mains supply and leads — these are not stated in the listing; give your local supply and the output leads you need.
- Quantity and trainers — the minimum order is 10 units; add a signal tracer or radio trainer to the same enquiry if required.
Frequently Asked Questions
What frequency range does it cover?
From 200 kHz to 280 MHz, in seven bands on a calibrated dial.
When does it use FM instead of AM modulation?
FM modulation is switched in automatically above 50 MHz. Below that, the output is modulated with a 400 Hz or 1 kHz tone.
What is the output level?
The output is variable from 0 to 200 mV.
How is it different from the R.F. Oscillator?
The R.F. Oscillator covers 100 kHz to 30 MHz in eight bands with continuous-wave or 400 Hz modulated output. This model reaches 280 MHz and adds FM above 50 MHz for FM radio and TV work.
Who manufactures it?
Jain Laboratory Instruments Pvt Ltd, trading as JLab, makes it at its works in Ambala, Haryana.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an Indian manufacturer of electronics training equipment and laboratory instruments, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The AM/FM oscillator is built in JLab’s own works, not resold from a trader, so training institutes, colleges, dealers and importers buy direct from the maker; every unit is visually inspected, and follow-up orders go back to the same works. JLab exports worldwide and ships to buyers in every region — for example Bolivia in South America, the UK in Western Europe, Bangladesh in South Asia, Hong Kong in East Asia and the USA in North America. Tender information is on the JLab lab tenders page.
