The Tektronix MDO4000C Mixed Domain Oscilloscope integrates up to six instruments into a single platform for simultaneous analysis of analog, digital, and RF signals. Built around a 4-channel oscilloscope with bandwidth options from 200 MHz to 1 GHz (upgradeable), it captures waveforms at rates exceeding 340,000 wfms/s with 20 M record length and 8-bit vertical resolution (11-bit in high resolution mode). The instrument supports over 125 trigger combinations including runt, glitch width, setup/hold time violations, and serial packet detection – ideal for isolating intermittent faults in embedded systems and RF designs.
