Synthesized Signal Generators TFG3630 TFG3630 synthesized signal generators with PLL technique and use the FPGA  to control screen display and output, with excellent technical performances and powerful function which are necessary for the experimental detection circuit and device detection. Large color LCD interface can show a variety of working parameters. Keypads and knob are convenient for operation. China Digital Multimeters China Frequency Characteristic Analyzer China Frequency Counter Features Frequency resolution: 3Hz Unlimited measurement range: digital setting directly for the whole range. Non-intergraded process: up to the stable value immediately when switching, continuous signal phase and amplitude without deflection. Sweep characteristics: with the function of frequency sweep and power sweep. Start point and stop point can be set arbitrarily. Modulation characteristics: pulse modulation signal with user-defined can be output. Operation mode: key operation, TFT-LCD interface, direct digital setting, continuous adjustment by knob. High reliability: large scale integrated circuit, SMT, high reliability and long service life.
