Features: 2in1 Design with Reliable Quality: Handheld 2in1 dual channel digital fluorescence oscilloscope signal generator. As an oscilloscope, it has 180MHz-3DB analog bandwidth and 500MSPS real-time sampling rate. Built-in 20MHz DDS function signal generator with 14 kinds of standard function signals, output amplitude fixed at 1VPP, sinewave frequency up to 20MHz, other waveform frequency up to 10MHz. Digital Fluorescence Display Technology: 2.8-inch IPS display with clear definition, color temperature display and multi-level grayscale display capability; waveform changes can be clearly seen in one minute. 50,000wfms/s Waveform Refresh Rate: Better capture the signal so that there is nowhere for abnormal waveforms to hide. Accurate Real-time Trigger System: With complete trigger function, automatic, single, regular three trigger modes; rising-edge trigger mode, falling-edge trigger mode. Adaptive Adjustable Trigger Suppression: Adapts high-frequency, low-frequency, and high-noise signals for cleaning stable waveforms. Large Time Base Scrolling Mode: In scroll mode, slow level changes can be monitored in real time. ZOOM Scaling Time Base: Provide an additional amplification time base. It can provide 2~1000 times amplification view effect in running or pause state. Digital Fluorescence XY Mode: Support digital fluorescence technology, dual-channel generate a closed curve graph can be used to compare the amplitude, frequency, phase of two groups of signals. 5mV High Sensitivity Ultra-high Waveform Signal-to-Noise Ratio: The analog front-end uses outstanding shielding measures and a stable feedback system; all parts with sources of interference are located away from the analog front-end. 20M Hardware Bandwidth Limit: The analog front end has a built-in switchable 20MHz hardware bandwidth limiting component, and the -3DB attenuation bandwidth is 20MHz when turned on. Special Truncated Output Function: Intercept part or all of various signals measured by oscilloscope to be used as output signal of signal generator, up to 500 custom signals can be stored. 400V High-voltage Burn-in Protections: The analog front-end input stage is designed with high-voltage resistance, and the overall design can achieve 400V burn-in resistance in any gear. Built-in Rechargeable Lithium Battery: Built-in 3000mah high-capacity rechargeable lithium battery, up to 4 hours of life, can be set from 5 minutes to 2 hours of timeout time, support 5V2A quick charging. One-Button Auto Adjustment: Manual cursor measurement, equipped with efficient one-key auto adjustment function, signal measurement is easy and fast; cursor accurate measurement of waveform parameters. FFT Simple Spectrum Display: Qualitative overview of the current signal spectrum components.
