Product Description After O7 Upgrade: Peak detection for certain power supply analyses. Improved high-resolution mode for cleaner, more detailed waveforms. Removes the 50M limit and fixes issues with smaller time base waveforms. New sampling mode in menu for adjusting high resolution. Performance of the O7 oscilloscope matches the O9 after the upgrade. Features: 3-in-1 Design & Comprehensive Measurement Integrates a 25MHz oscilloscope, a 6000 count multimeter, and a single channel signal generator in one unit with a 3.98-inch TFT IPS display for precise electronic signal detection and analysis. Oscilloscope Function Features 25MHz bandwidth, 208MSa/s sampling rate, and three waveform trigger modes for accurate signal detection. Supports manual settings for various parameters and can connect to computers via USB for analysis. Signal Source Function Measures various signal waveforms such as sinewave, squarewave, and others, providing flexibility for emulating signal environments. Multimeter Functions Supports multiple measurements including DC/AC voltage and current, resistance, capacitance, and temperature. Comes with v-alert and buzzer functions for enhanced utility in electronic overhauling and maintenance. Premium Material & Digital Display Compact design with protective silicone coating for slip, drop, and impact resistance. Real-time display of measurement parameters on a clear 480x320 TFT IPS display. Rechargeable Battery & Wide Applications Includes built-in high-capacity lithium batteries for long-lasting power. Ideal for laboratory research, teaching demonstrations, and DIY maintenance.
