It is a oscilloscope .The software and oscilloscope can be connected wirelessly, enabling physical isolation of the test site from the operator's operating site, such as high-voltage devices that cannot be accessed by the debugger, devices in hazardous environments, devices in motion, and devices that are susceptible to interference. It can not only be Wi-Fi wireless connection, but also retains the USB connection, when the Wi-Fi signal is not smooth, you can use USB to connect the computer to work. 5 channel input, synchronous display Automatic measurement of amplitude, 4 measurement modes optional Input capture (trigger) function Any channel can be set as a capture (trigger) source Can set rising or falling edge capture (trigger) signal Capture (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 any two channels of differential signal Lock signal to expand and compress waveforms up to 90 hours Suitable 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 Parameters Wireless Communication: Wi-Fi 2.4G Interface type: Micro-USB 2.0 Signal input interface type: BNC interface, connected with the oscilloscope probe line Maximum sampling rate: 1MHz ( 1*1MHz / 2*1MHz / 3*0.5MHz / 4*0.5MHz / 5*0.33MHz ) Operating voltage: 5 V Micro-USB interface power supply Measurable frequency range: 0Hz-250 kHz Amplitude adjustment range(/): 2 mV; 5mV; 10mV; 20mV; 25mV; 40mV; 50mV; 80mV; 0.1V; 0.2V; 0.5V; 1V; 2V; 5V; 10V Input impedance: 1 MΩ/20pF Maimum measurement voltage: ±80 V, Colour:As Shown Material:plastic<
