This instrument combines oscilloscope, signal generator, multimeter in one, powerful and practical. 2. Adopting advanced ARM processor and dual chips, it has high-performance sampling channel that can achieve sampling rate of 250MSa/s and maximum bandwidth of 30MHz. 3. You can observe signal data by serial port center. 4. Color TFT screen displays clear and stable waveform. 5. Support for firmware program upgrade via USB. 6. With edge trigger function, it can automatically detect (support 50Hz-60MHz). 7. Multiple waveform math addition functions. 8. Support automatic shutdown function and power saving mode: time can be set. 9. Waveforms can be saved as screenshots and imported to the computer via USB.   Specification: Brand: Jinhan Model: JDS3012A Power supply: 1 * 18650 3.7V 3600mAh battery (not included) Item Size: 22.6*13.8*4.0cm / 8.9*5.4*1.6in Weight: Approx. 1372g/48.4oz Oscilloscope: Max sampling rate: 250MSa/S Channel: 1 analog channel + 1 digital channel Bandwidth: 30MHz Vertical resolution: 8bit Vertical accuracy: ±3% Input range: 10mV-5V (Probe 1X), 100mV-50V (Probe 10C), 1V-500V (Probe 100X) (1, 2, 5 Step) Input impedance: 1MΩ 25pF Input coupling: DC/AC Display mode: Y-T Time Range: 10ns-50ms(1,2.5 step), 100ms-5s (scan) Storage depth: 16Kpts Trigger mode: Auto, Normal and Single Trigger Type: Rise, Down Automatic detection: Support 50Hz-60MHz Measurement: The peak to peak value, duty cycle, frequency, cycle Screen: 4.3 inch 16 bit true color TFT 400*272   Multimeter: Max display: 6000 counts DC current: 60.00mA/600.0mA, 6.000A/10.00A.
