Features:1. The display interface adopts 2.4-inch TFT color LCD, which makes the operation more intuitive and convenient.2. The instrument USES direct digital frequency synthesizer (DDS) technology to provide stable, accurate, pure and low-distortion signals.3. Rich keyboard shortcuts and graphical user interface simplify each operation, easy to operate.4. Surface mount technology can improve anti - interference and service life.5. The instrument USES A 14-bit high D/A conversion chip (5Vpp output quantization error less than 1mV), A sampling rate of 250MSa/s, and A vertical resolution of 14bit.6. Various modulation types: AM, FM, PM, ASK, FSK and PSK modulation.7. Scanning function: four properties of the scannable signal, including frequency, amplitude, offset and duty cycle; It has two kinds of Linear and Logarithm scanning type; Scanning time: 0.01S-9999.99S; Up, down and round trip scanning directions.9. Function of 100M frequency meter: it can measure frequency, period, pulse width and duty ratio. The frequencies that work are 100MHz and Min. Frequency behavior: 0.01 Hz.10. Counter function: there are 2 coupling measurement modes, including DC coupling and AC coupling. This design can solve the inaccurate problem of ac coupling.11. Output short circuit protection: when the load short circuit, all channels can work for more than 60 seconds.Specification: Item Type: Signal GeneratorMaterial: PlasticModel: FY6900Frequency parameterFrequency Range:Sine wave: 0Hz~30MHzSquare wave: 0Hz~20MHzTriangle wave: 0Hz~10MHzSawtooth wave: 0Hz~10MHzFrequency range of arbitrary waves: 0 ~ 10MHzTTL / CMOS digital wave range: 0~20MHzMinimum width adjustment of pulse wave: 20nsHey.
