• Display: 7-inch color LCD (800 x 480 pixels). The display provides a clear and easy-to-read representation of the waveforms and measurement data.
• Waveform Capture Rate: 100,000 wfms/s. The waveform capture rate indicates how many waveforms the oscilloscope can acquire and display per second. A higher waveform capture rate increases the probability of capturing infrequent glitches or anomalies.
• Triggering: Edge, Pulse, Video, Slope, Alternative. The triggering system allows you to synchronize the oscilloscope's display with a specific event in the signal, making it easier to analyze the signal.
• Measurements: Automatic measurements for voltage, time, frequency, etc. The oscilloscope provides a variety of automatic measurements, which simplifies the process of analyzing signal characteristics.
• Connectivity: USB host, USB device, LAN. The connectivity options allow you to connect the oscilloscope to a computer for data transfer, remote control, and firmware updates.
