Features:1. Thisinstrument combines oscilloscope, signal generator, multimeter in one, powerfuland practical.2. Adopting advancedARM processor and dual chips, it has high-performance sampling channel that canachieve sampling rate of 250MSa/s and maximum bandwidth of 30MHz.3. You canobserve signal data by serial port center.4. Color TFT screendisplays clear and stable waveform.5. Support forfirmware program upgrade via USB.6. With edge trigger function, it can automatically detect (support 50Hz-60MHz).7. Multiplewaveform math addition functions.8. Supportautomatic shutdown function and power saving mode: time can be set.9. Waveformscan be saved as screenshots and imported to the computer via USB.Specification:Brand: JinhanModel: JDS3012APower supply: 1 * 18650 3.7V 3600mAh battery (not included)Item Size: 22.6*13.8*4.0cm / 8.9*5.4*1.6inWeight: Approx. 1372g/48.4ozOscilloscope:Max samplingrate: 250MSa/SChannel: 1analog channel + 1 digital channelBandwidth: 30MHzVerticalresolution: 8bitVerticalaccuracy: 3%Input range: 10mV-5V(Probe 1X), 100mV-50V (Probe 10C), 1V-500V (Probe 100X) (1, 2, 5 Step)Input impedance:1M25pFInput coupling:DC/ACDisplay mode:Y-TTime Range: 10ns-50ms(1,2.5step), 100ms-5s (scan)Storage depth:16KptsTrigger mode: Auto,Normal and SingleTrigger Type:Rise, DownAutomaticdetection: Support 50Hz-60MHzMeasurement: Thepeak to peak value, duty cycle, frequency, cycleScreen: 4.3inch 16 bit true color TFT 400*272Multimeter:Max display: 6000countsDC current: 60.00mA/600.0mA,6.000A/10.00A.AC current: 60.00mA/600.0mA,6.000A/10.00A.Resistance: 600.0, 6.000k, 60.00k, 600.0k, 6.000M, 60.00M.Capacitor: 40.00nF,400.0nF, 4.000uF, 40.00uF, 400.0uF, 4000uF(30sec).Diode: 0V~2.0V.On-offdetection: in 600geardetection, buzzer when less than 30 Signal Generator:Frequency: 0Hz- 10MHzDuty cycle: 0%- 100%Amplitude: 100mV- 4VOffset: 0V - 2VSerial Center: Baud rate: 115200- 1200Data bits: 8,9Parity bit: NO,ODD, EVENStop bit: 1, 0.5,2, 1.5Hex: 10, 16Recorder: Time base: 100ms- 5sPackage list:1 * Oscilloscope1 * Battery Charger1 * CD1 * Screen Protector1 * USB Cable1 * Protective Cover4 * Identification Ring1 * BNC to alligator clip test cable1 * Oscilloscope Probe2 * Multimeter Probes1 * Black Bag
