Q1: What is a function signal generator?
A1: A function signal generator is a signal-generating device that can generate some specific periodic time function waveforms (sine waves, square waves, triangle waves, sawtooth waves and pulse waves, etc.). In addition to being used for communication, instrumentation and automatic control system testing, function signal generator is also widely used in other non-electrical measurement fields.
Q2: How does a function signal generator work?
A2: The function signal generator system is mainly composed of the main vibration level, the main vibration output adjustment potentiometer, the voltage amplifier, the output attenuator, the power amplifier, the impedance converter and the indicating voltmeter. When a small signal sine wave is input to the input end, the signal is transmitted in two ways, one way completes the rectification and voltage doubling function to provide working power, and the other way enters the input end of an inverter to complete the signal amplification function. The amplified signal is processed by the gate circuit of the latter stage, converted into a square wave and then output, and the output terminal is an adjustable resistance.
Q3: How to choose a function signal generator?
A3:
- The function signal generator should meet the signal types and functions required by the application. From the application point of view, if it is used for digital signal testing, the vector signal source is more suitable; if it is mainly used for basic circuit experiments and ordinary electrical repairs, the ordinary function generator is more suitable; if it is mainly used for debugging the sensitivity of the walkie-talkie, the high-frequency signal generator is necessary.
- The function signal generator should meet the frequency and output amplitude required by the application. The frequency coverage and modulation mode of the signal generator as well as the signal output amplitude should meet the needs of the application.
- Excellent pre-sale and after-sale service. In addition to the function signal generator, service and maintenance coverage before and after purchase is also important. It is also very necessary to understand the warranty period of the product and after-sales service. sisco provides professional pre-sales service and after-sales service, and the function signal generator is provided with a 365-day warranty.
Tips: What is a function signal generator?
Function signal generator is a device that can provide electrical signals of various frequencies, waveforms, and output levels. When measuring the amplitude characteristics, frequency characteristics, transmission characteristics, and other electrical specifications of various telecommunication systems or telecommunication equipment, or when measuring the characteristics and specifications of components, function signal generator is used as a signal source or excitation source for testing. Function signal generator, also called signal source or oscillator, has a wide range of applications in the field of production practice and technology.
sisco function signal generator system is mainly composed of the main vibration stage, main vibration output adjustment potentiometer, voltage amplifier, output attenuator, power amplifier, impedance converter and indicator voltmeter. When a small signal sine wave is input to the input terminal, the signal is transmitted in two ways. One way completes the rectification and voltage doubling function to provide working power, and the other way enters the input end of an inverter to complete the signal amplification function. The amplified signal is processed by the gate circuit of the subsequent stage and converted into a square wave and output, the output end is an adjustable resistor. Various waveform curves generated by the function signal generator can be represented by trigonometric equations.
