With 5 GS/s maximum sample rate, 20 M record length on all channels, and a 340,000 wfm/s FastAcq® waveform capture rate, the time-domain oscilloscope and the dedicated RF input are time-synchronized in a single acquisition system, eliminating the need to manage and re-learn a separate spectrum analyzer. ### What is the MDO4104C used for? The MDO4104C is used to debug, validate, and characterize embedded systems that contain a mix of analog signals, digital buses, and RF activity in a single device under test. Typical applications include embedded design and debug, power supply characterization, EMI troubleshooting, wireless integration with Bluetooth / 802.11 / ZigBee, education in mixed-signal and RF coursework, and manufacturing test or troubleshooting stations where bench space is constrained. ### Why integrate spectrum analysis into an oscilloscope? The MDO4000C Series is the world's first oscilloscope with a built-in spectrum analyzer. The integration enables time-correlated capture of analog, digital, and RF signals from a single trigger event, so an engineer investigating an EMI emission or a wireless transmit/receive event can see the time-domain cause and the frequency-domain effect in one acquisition — something a separate scope and spectrum analyzer cannot do because each has its own independent acquisition system and trigger. Factually, the MDO4104C provides 4 analog channels at 1 GHz bandwidth with 350 ps rise time, 5 GS/s maximum sample rate, and a 20 M record length on every channel. Compared to traditional swept spectrum analyzers that typically offer 10 MHz capture bandwidth, the MDO4000C delivers ≥1 GHz of capture bandwidth in the frequency domain — at spans of 1 GHz and below the spectrum is generated from a single acquisition, eliminating the gaps inherent to swept architectures. The MDO4000C platform supports automated trigger, decode, and search on the principal embedded and industrial serial standards (I²C, SPI, RS-232/422/485/UART, USB 2.0, Ethernet 10/100BASE-T/TX, CAN, CAN FD, LIN, FlexRay, MIL-STD-1553, I²S/LJ/RJ/TDM) and aligns with widely deployed standards including LXI Core 2011, IEEE 488.1 (GPIB via TEK-USB-488), CISPR-class EMC pre-screening workflows, and the IEC 61000-3-2 power-quality framework when the DPO4PWR power analysis option is installed. ### Where the MDO4104C fits in the Tektronix mid-range - Versus an MSO/DPO2000B series scope, the MDO4000C adds the integrated spectrum analyzer option, deeper 20 M record length, 4 analog channels standard, and FastAcq® at >270,000 wfm/s (>340,000 wfm/s on the 1 GHz model) for visibility into rarely occurring events. - Versus an MDO3000 series scope, the MDO4000C extends the spectrum analyzer ceiling from 3 GHz to an optional 6 GHz, adds Ethernet and BroadR-Reach decode workflows on the protocol side, and provides Vector Signal Analysis and spectrogram displays not available on the MDO3000. - Versus an MSO/DPO5000B series scope, the MDO4000C trades a portion of vertical analysis depth for the integrated spectrum analyzer that the 5000B series does not include — making it the correct choice when RF-domain visibility is required in the same instrument as the digital and analog channels. ## Accessories Supplied Item Description Passive Voltage Probes TPP1000: 1 GHz, 10X, 3.9 pF (one per analog channel) Front Cover 200-5130-xx Accessory Bag 016-2030-xx Installation and Safety Instructions 071-3448-xx (English / French / Japanese / Simplified Chinese printed; full manuals available at tek.com/manual/downloads) Power Cord Region-specific (Opt.
