2. Product Features

• Dual Channel Operation: Supports two channels for simultaneous signal input and analysis.
• High Bandwidth: 120MHz bandwidth when channel two is closed, 60MHz when both channels are open.
• High Sampling Rate: 500MS/s sampling rate for detailed waveform capture.
• Integrated Signal Generator: Outputs various waveforms (sine, square, triangle, half-wave, sing-wave) with adjustable frequencies. Sine wave frequency range: 0-10MHz; other waveforms: 0-2MHz.
• XY Mode: Capable of displaying Lissajous graphics or VI curves.
• Low Vertical Sensitivity: 10mV/div sensitivity for measuring weak signals or power supply noise.
• Waveform Storage: Supports saving captured waveforms.
• Measurement Options: Includes 14 measurement options such as Frequency, Peak-to-Peak, Duty Cycle, Amplitude, RMS, Average, Period, Pulse Width, Max, Min, Top, Base.
• Anti-Burn Protection: Designed with auto anti-burn features for enhanced safety.
• Video Output: Screen content can be projected to external displays.
