Cheap frequency signal generator for sale
TFG1900B Series belonging to a low price function generator, with one channel output, 3MHz/5MHz/10MHz/20MHz for Sine, high precision PCB designed, can make the test quickly and accurately. Working at AC 100-240V voltage power, adopting the DDS technique, it is an inexpensive electronics test and measurement instrument for R&D, education, etc.
Application
Signal Testing & Circuit Debugging
Generate sine, square, triangle, and pulse waveforms to test analog/digital circuits.
Verify amplifier frequency response, filter characteristics, and oscillator circuits.
Frequency Response Analysis
Test the bandwidth of amplifiers, filters, and sensors by sweeping frequencies (e.g., 1 Hz to 20 MHz).
Characterize resonant circuits (LC, RLC) and transducer responses.
Education & Training
Teach waveform fundamentals (frequency, amplitude, phase) in labs.
Demonstrate modulation techniques (AM, FM, PWM).
Component & Sensor Testing
Drive piezoelectric transducers, ultrasonic sensors, and MEMS devices.
Test passive components (capacitors, inductors) with frequency sweeps.
Troubleshooting & Repair
Inject signals into faulty circuits to trace signal paths in audio/RF systems.
TFG1900B can output maximum 20 Vpp signal at open circuit.
TFG1900B can provide FM, AM, PM, PWM, FSK modulations to meet the test requirement.
TFG1900B also provide frequency sweep function through internally, externally or manually triggered.
TFG1900B can output 16 kind waveforms, including Sine, Square, Ramp, Exp., Log. Noise, etc., which can meet the basic test requirement in education or laboratory.
