Product Description:
EE1641B1 function signal generator is a precise test instrument, with continuous signal, scan signal, function signal, pulse signal and other output signals and external frequency measurement functions, it is required for engineers, electronic laboratories, production lines, teaching and scientific research. more ideal equipment. Can directly generate sine wave, triangle wave, square wave, sawtooth wave and pulse wave, and has VCP input control function. TTL/CMOS and OUTPUT synchronous output. The DC level can be continuously adjusted, the frequency meter can be used for internal frequency display or external frequency measurement, and the voltage is displayed by LED. When the function signal generator is working, two constant current sources are generated by the V/I voltage-current converter. The constant current source charges and discharges the time base capacitor C. The charging and discharging of the capacitor cause the voltage on the capacitor to rise and fall linearly with time, respectively, so that the triangular wave voltage is obtained at both ends of the capacitor. The triangular wave voltage is obtained by the square wave forming circuit to obtain the square wave voltage. The triangular wave voltage is obtained by the sine wave forming circuit to obtain the sine wave voltage, which is finally output through power amplification.
Features:
1. Using large-scale monolithic integrated precision function generator circuit, the machine has high reliability and excellent performance/price ratio.
2. Using a single-chip microcomputer circuit for whole-cycle frequency measurement and intelligent management, users can intuitively and accurately understand the frequency amplitude of the output signal (especially at low frequencies). Therefore, the user is greatly facilitated.
3. The machine adopts a precision current source circuit, so that the output signal has a very high precision in the entire frequency band. At the same time, the conversion of various current sources makes the instrument not only have basic waveforms such as sine wave, triangle wave, square wave, but also It has the output of various asymmetric waveforms such as sawtooth wave and pulse wave, and can realize the scanning function for various waveforms at the same time.
4. The whole machine adopts large-scale integrated circuit design, optimal design circuit, and derating of components to ensure high reliability of the instrument, and the mean time between failures is as high as thousands of hours.
