The Keysight DSOX1204G is a 4-channel digital oscilloscope from the InfiniiVision 1000 X-Series, delivering 70 MHz base bandwidth with upgradeable options to 100 MHz or 200 MHz. It integrates a 20 MHz waveform generator, enabling simultaneous signal capture and stimulus in a single compact instrument. The oscilloscope achieves up to 2 GSa/s sample rate, 2 Mpts memory depth, and 8-bit vertical resolution with effective 12-bit resolution through oversampling and averaging. With a 7-inch WVGA TFT display, 1 MΩ input impedance, and input sensitivity from 500 µV/div to 10 V/div, it handles signals up to 150 Vrms (200 Vpk). Advanced trigger types include edge, pattern/state, pulse width, setup and hold, rise/fall time, video, I²C, RS-232/422/485/UART, SPI, CAN, and LIN. The horizontal system spans 5 ns/div to 50 s/div with 2.5 ps resolution and supports main, zoom, roll, and XY acquisition modes. Time base accuracy of 50 ppm with ±5 ppm annual aging ensures reliable long-term measurements. At 3.23 kg and 130 mm × 314 mm × 165 mm, the instrument fits laboratory and field-service environments. Standard 3-year warranty and universal 100–240 V power input provide immediate deployment flexibility.
