Signal Generator And Amplifier (European Version)
Signal Generator And Amplifier (European Version) (Product Code: SLE/PHY/293) is a power signal generator used to drive loudspeakers, vibrators and other low-impedance loads in physics and electronics laboratories. It spans 0.1 Hz to 99.9 kHz on a digital display with 0.01% frequency accuracy and delivers up to 4.5 W across the whole range for every waveform. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for laboratories on 220 - 240 V, 50 Hz mains.

What Is the Power Signal Generator Used For?
Its 4.5 W low-impedance output is what makes this generator useful in physics. It can drive a vibration generator for standing waves on strings, a loudspeaker for sound interference and resonance tube work, or the coil of a reed relay for capacitor charging experiments. The digital display and 0.01% accuracy mean students read the frequency straight from the panel, without a separate counter, which speeds up graph-based practicals such as frequency against tension or length.
For electronics, the 600 ohm high-impedance output with its x0.1 and x0.01 attenuators provides small, clean signals for amplifier and filter circuits. Because the signal output floats with respect to ground, decide which terminal connects to the oscilloscope earth before measuring. The unit tolerates an accidental short circuit on the output, but it should never be opened by users; refer any fault to us for advice.
What to Specify When Ordering
- Number of units required for your laboratories.
- Confirmation that your mains supply is 220 - 240 V, 50 Hz; if not, ask us about an alternative model.
- The loads you plan to drive, such as loudspeakers or vibration generators.
- Whether oscilloscopes, leads or vibrators should be added to the quotation.

Frequently Asked Questions
What frequency range and accuracy does the Signal Generator And Amplifier (European Version) offer?
The Signal Generator And Amplifier (European Version) covers 0.1 Hz to 99.9 kHz in six decades, shown on a digital display. Frequency accuracy is 0.01% (100 ppm) on all ranges, so readings can be taken directly from the panel.
How much power can the Signal Generator And Amplifier (European Version) deliver?
The Signal Generator And Amplifier (European Version) delivers a maximum of 4.5 W over its entire frequency range for all waveforms. Maximum power transfer occurs into a 4 ohm load, where the low-impedance output gives 6 V RMS.
What is the difference between the two outputs on the Signal Generator And Amplifier (European Version)?
The Signal Generator And Amplifier (European Version) has a low-impedance power output for loads around 4 ohm, and a high-impedance output of up to 17 V peak to peak from 600 ohm. Only the 600 ohm output has the x1, x0.1 and x0.01 attenuator.
What mains supply does the Signal Generator And Amplifier (European Version) need?
The Signal Generator And Amplifier (European Version) runs on 220 - 240 V, 50 Hz mains and is protected by an internal T315mA L fuse. Its earth is connected through the power cord, while the signal output floats with respect to ground.
Is the Signal Generator And Amplifier (European Version) protected against short circuits?
Yes, the Signal Generator And Amplifier (European Version) is a robust instrument that withstands a prolonged short circuit on its output. Users should not open the case; if a fault appears, contact us through the contact page for advice.
