Tektronix MDO4034C Mixed Domain Oscilloscope

The Tektronix MDO4034C is a mixed-domain oscilloscope that combines oscilloscope, spectrum analyzer, and logic analyzer capabilities in a single instrument. It delivers time-correlated acquisition of analog, digital, and RF signals for embedded systems, wireless communications, and EMI troubleshooting. The 4-channel oscilloscope operates at 350 MHz bandwidth with 2.5 GS/s sampling and 20 Mpoints record length, while optional spectrum analysis extends to 3 GHz or 6 GHz, and 16-channel logic analysis provides 60.6 ps timing resolution via MagniVu™. Over 125 trigger combinations cover runt, logic, pulse width, setup/hold violation, serial packet, parallel data, and RF power level detection. Advanced triggering includes I2C, SPI, RS-232/422/485, USB 2.0, Ethernet, CAN, CAN FD, LIN, FlexRay, MIL-STD-1553, ARINC-429, and I2S protocols, plus video standards from NTSC to 1080p/60. The instrument delivers 29 to 45 automated measurements, FFT analysis, waveform histograms, trend plots, and Mask/Limit testing. Optional arbitrary waveform generation produces signals to 50 MHz with 250 MS/s sampling. Vertical sensitivity spans 1 mV/div to 10 V/div with 8-bit resolution (11-bit in high-resolution mode). Maximum waveform capture rate exceeds 340,000 wfms/s. The 4-digit digital voltmeter and 5-digit frequency counter provide direct measurements. TekVPI probe interface supports active 50 Ω probes with optional RF input adapter; optional preamplifier provides 12 dB nominal gain across 9 kHz to 6 GHz. Wave Inspector® enables rapid waveform navigation and automated search across large datasets.
