How Does It Compare with the JLab A.F. Oscillator Digital?
| Model | Frequency range | Waveforms | Output | Output impedance | Frequency meter |
|---|---|---|---|---|---|
| This instrument (EL-TAMI-1020) | 1 Hz to 1 MHz, five decade ranges | Sine, square | 1 mV to 20 V open circuit, six steps, continuously variable | 600 ohm | Built in, 10 Hz to 10 MHz on separate terminals |
| A.F. Oscillator Digital | 1 Hz to 250 kHz, five selectable bands | Sine, square, triangular | 1 to 10 V p-p, three coarse steps and a fine control | 50 ohm | Not listed (digital readout of its own frequency) |
Choose this model when you need frequencies up to 1 MHz, millivolt-level signals, a 600 ohm audio output or a frequency meter for checking other circuits. The A.F. Oscillator Digital suits buyers who also want a triangular wave and a low 50 ohm output impedance within its 250 kHz range.
What Is the A.F. Oscillator Function Generator Used For?
An audio-frequency oscillator is the standard signal source of an electronics lab. With an A.C. millivoltmeter or an oscilloscope, students feed a fixed-level sine wave into an amplifier or filter, step the frequency through the audio band and plot the frequency response; the flat ±0.3 dB output from 20 Hz to 20 kHz means changes in the reading come from the circuit, not the generator. The same source drives series and parallel LCR resonance experiments, bridge measurements, loudspeaker and sound experiments, and Lissajous-figure frequency comparisons on a CRO. The square wave shows how an amplifier handles fast edges and low-frequency tilt.
The built-in frequency meter has its own input terminals, so it can also read the frequency of an external signal — for example a transistor oscillator that students have wired on a breadboard — anywhere from 10 Hz to 10 MHz. This makes the instrument a practical function generator for B.Sc. physics and electronics practicals, engineering and polytechnic labs, and ITI electronics workshops. Because the output impedance is 600 ohm, the voltage at the load falls when a low-resistance load is connected; read the level at the load, not at the dial, when the exact amplitude matters.
What to Specify When Ordering
- Model — this sine and square generator with built-in frequency meter, or the A.F. Oscillator Digital if you need a triangular wave.
- Mains supply — the instrument works on 220 V, 50 Hz; state your local supply.
- Leads and companion instruments — list the output and frequency-meter leads you need, and add an oscilloscope or millivoltmeter to the same enquiry.
- Quantity — the minimum order is 10 units.
Frequently Asked Questions
What waveforms and frequency range does it give?
Sine and square waves from 1 Hz to 1 MHz, selected in five decade ranges, with a listed frequency accuracy of ±2% or 1 Hz.
What output voltage and impedance does it have?
The output can be set from 1 mV to 20 V open circuit in six steps with continuous control between them. The output impedance is 600 ohm, so the voltage across a matched 600 ohm load is half the open-circuit value.
Can the frequency meter measure other signals?
Yes. Separate terminals are provided, and the frequency meter reads from 10 Hz to 10 MHz, which covers the instrument’s own output and most oscillator circuits built in a teaching lab.
How flat is the output across the audio band?
The listed frequency response is ±0.3 dB from 20 Hz to 20 kHz, which is why it suits amplifier and filter frequency-response experiments.
How does it differ from the A.F. Oscillator Digital?
This model reaches 1 MHz, offers sine and square waves, has a 600 ohm output and includes a separate frequency meter. The A.F. Oscillator Digital covers 1 Hz to 250 kHz, adds a triangular wave and has a 50 ohm output.
What details are needed for an export quotation?
Send the quantity, the destination country and port or city, delivery terms (for example FOB or CIF), your mains supply, any packing or labelling instructions and the tender reference if there is one.
Who manufactures this instrument?
JLab — Jain Laboratory Instruments Pvt Ltd — builds 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, a manufacturer of electronic test instruments and science lab equipment in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. This generator is produced in JLab’s own works, not bought from a trader, so colleges, institutes, dealers and importers buy it directly from the maker, every unit is visually inspected before dispatch, and repeat orders are served by the same factory. The company is registered under CIN U29309HR2017PTC069123 and holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise). JLab exports worldwide and ships to buyers in every region — for example Vanuatu in Oceania, Belize in Central America and the Caribbean, Libya in North Africa, Yemen in the Middle East and Sri Lanka in South Asia. Tender buyers can refer to the JLab lab tenders page.
