Product description: LongWei LW-1641 2 MHz function generator - 1 channel
The LW-1641 is a high-end LongWei functional waveform generator , designed with stability, wide bandwidth and functionality in mind. It can generate up to seven different waveforms : sinusoidal, rectangular, triangular, sawtooth and pulse - in positive and negative versions. The generator also offers the possibility of adjusting symmetry, DC offset and cooperation with TTL / CMOS systems . The built-in frequency counter allows you to measure external signals in the range of 1 Hz to 30 MHz . The equipment is ideal for laboratories, schools, workshops and engineering projects.
LongWei LW-1641 function generator 2 MHz - 1 channel.
Generates many forms of output signal.
Main features of the generator
- Frequency range from 0.1 Hz to 2 MHz - allows you to generate signals from very low to high frequencies, useful in a wide range of laboratory applications
- Wide selection of waveforms - allows testing of various types of electronic and signal systems
- Digital logic compatible TTL/CMOS output - can be directly connected to microcontrollers and digital test systems
- Adjustable waveform symmetry from 90:10 to 10:90 - allows you to set the exact duty cycle for square and pulse signals
- Low distortion of the sinusoidal signal < 1% - ensures high quality waveforms for precise measurements
- DC ±10V offset adjustable output - allows signal level shifting, useful in analog testing
- Fast square wave rise time <100 ns="" strong=""> - provides a sharp signal edge, ideal for testing fast digital circuits
- Signal attenuation 20 dB or 40 dB - makes it easy to match the signal level to the sensitivity of the tested system
- VCF input - the ability to control the signal frequency using an external voltage
- Built-in frequency counter up to 30 MHz - allows you to measure the frequency of external signals with high accuracy
Practical applications
The LW-1641 is perfect for technical education, testing of analog and digital systems, scientific research and servicing of electronic equipment . Thanks to its low distortion and wide functionality, it is used both in research laboratories and among hobbyists and designers.
Supports frequency counting from 1 Hz to 30 MHz.
The generator operates with a supply voltage of 110 V to 220 V.
