Function introduction: 2 channel input, synchronous display. Automatic measurement of amplitude, 4 measurement modes optionalInput capture (trigger) function. Any channel can be set as a capture (trigger) source. Can set rising or falling edge capture (trigger) signalCapture (trigger) signal level adjustable. Data can be saved to the computer, automatically ferred to the saved data when the software is started. Data can be backed up, and later at any time to view the backup data waveform. Can display two channels of differential signalLock signal to expand and compress waveforms up to 90 hoursSuitable for monitoring the operation of electrical equipment for a long time and archiving. Suitable for collecting and archiving data such as temperature, humidity and light for a long time Technical ParametersInterface type: Micro-USB 2.0Signal input interface type: BNC interface, connected with the oscilloscope probe lineMaximum sampling rate:1MHz ( 2 x 1MHz )Operating voltage: 5 V Micro-USB interface power supplyConsumption current: Less than 2 AMeasurable frequency range: 0Hz-----250 kHzAmplitude adjustment range(/):2 mV; 5mV; 10mV; 20mV; 25mV; 40mV; 50mV; 80mV;0.1V; 0.2V; 0.5V; 1V; 2V; 5V; 10VInput impedance: 1 M/20pFMaximum measurement voltage: 80 V,Time domain range: 10 uS/-----10800 S/Data recording and storage depth: 8388608 x 5Maximum record and save data time: 90 hoursHost size: 115mm x 70mm x 29mmConnection methodConnect the oscilloscope to the computer using the USB cable.material: plasticColor: as shown Package Contents:1 x Fosc21C1 oscilloscope2 x BNC connector1 x USB data cable Only the above package content, other products are not included.Note: Light reflection and different displays may cause the color of th
