Feature: 1. [Oscilloscope Mode] Waveform refresh rate up to 10000wfms/s. 2 way inputs, bandwidth of up to 200MHZ, providing better signal reception. Real time sampling rate is 1GSa/s, the record length can achieve 8k points. 2. [Multimeter Mode] 4 1/2 bits of true RMS. Supports voltage, current, resistance, capacitance, diode, on off test. Maximum input voltage is 750V AC and 1000V DC. 3. [Multi Function] Equipped with automatic range function, convenient for testing and debugging, with reading and waiting function, relative measurement function, more practical. 4. [High Performance] The signal source adopts a 25MHz output frequency, 1GS/s sampling rate, 14 bit vertical resolution, supports 1MΩ and 50Ω outputs. 5. [USB Type C Interface] Not only supports mobile power supply, but also supports adapter charging and top grade computer connection. Computers can read saved images or CSV waveforms, which is very useful for viewing and analyzing waveforms or sharing waveform data in the future.
