The Keysight DSOX1204G is a 4-channel digital storage oscilloscope from the InfiniiVision 1000 X-Series that combines measurement and signal generation in a single platform. This instrument delivers 70 MHz bandwidth (upgradeable to 100 MHz or 200 MHz) with 2 GSa/s interleaved sample rate and waveform update rates reaching 200,000 wfms/sec. Beyond oscilloscope functionality, it integrates a 20 MHz function generator, frequency response analyzer for Bode plots, serial protocol analyzer supporting I²C, SPI, UART/RS-232, CAN, and LIN, plus a digital voltmeter and frequency counter.
