This oscilloscope is consists of "software running on (Wins system) computers" and "oscilloscope". The software and the oscilloscope can be connected wirelessly, which enables physical isolation between the test site and the operation site of technical personnel, such as high-voltage equipment that is inaccessible to debuggers, equipment in hazardous environments, equipment in motion, and equipment susceptible to interference. It not only support WiFi wireless connection, but also retain the USB connection, which can be used to connect to the computers when the WiFi signal is unstable. Features: 5-channel input design, and synchronous display. Automatic amplitude measurement, 4 kinds of measurement mode can be selected by yourself. With input capture (trigger) function. Each channel can be set as a capture (trigger) signal source. Can set the rising edges or falling edges capture (trigger) signal. The capture (trigger) signal level can be adjusted. Data can be saved to PC, and the saved data can be automatically transferred when the software is started. Data can be backed up to view the backup waveform at any time. Support display the differential signal of any two channels. After locking the signal, the waveform can be expanded and compressed to view, up to 93 hours. Suitable for long-term monitoring and archiving of the operating conditions of electrical equipment. Suitable for long-term collecting and archiving data such as temperature, humidity, light, etc. Specifications: Name: Oscilloscope Material: plastics Wireless communication: Wi-Fi 2.4G Interface type: Micro USB 2.0 Signal input interface type: BNC interface, connected to a universal oscilloscope probe cable Maximum sampling rate: 150kHz Operating voltage: 5V Micro USB interface power supplys Current consumption:
