Feature: 1. There are 3 trigger modes: automatic, single, and normal. The single trigger mode tests unexpected non‑periodic signals, such as car ignition signals. 2. Normal trigger mode tests digital logic signals, such as infrared remote control signals. 3. Automatic trigger mode tests periodic analog signals, such as sinusoidal signals; a wide range of applications. 4. 100MHz bandwidth is almost omnipotent in the field of electrical signal measurement, for amplifiers, oscillators, automatic control systems, DC/DC conversion, inverter systems, switching power supplies, etc. 5. Engineering debugging tool: used for DIY production, inverter circuit, switching power supply, oscillation circuit, PWM drive, communication circuit, power amplifier circuit, mains measurement, bus circuit, etc. 6. A wide range of applications, multiple fields, electronic production, home appliance repair, automobile repair, equipment debugging, scientific research and education, product development, etc. Specification: Item Type: Digital Oscilloscope Product Material: ABS Product Color: Yellow Charging: 5V 1A/2A/3A/4A The Highest Test Voltage: 1 x 80V 10 x 800V LCD Screen Size: Approx. 6.1cm / 2.4in LCD Resolution: 320 x 240 Display Technology: TFT Built-in Battery: Lithium battery 5000mAh Bandwidth: 100MHz Sampling Rate: 500MS/ s Standby Time: 8 hours standby External Trigger Voltage: 0-80V.
