The Tektronix MSO46 4 Series Mixed Signal Oscilloscope delivers 500 MHz bandwidth and 6 FlexChannel inputs for analyzing embedded systems, power electronics, and automotive applications. Each FlexChannel captures either one analog signal or eight digital logic inputs using optional TLP058 probes—enabling up to 48 digital channels. With 6.25 GS/s sample rate across all channels, 12-bit ADC resolution (16-bit in High Res mode), and waveform capture exceeding 500,000 waveforms/s, this instrument handles complex signal characterization in power supply design, system integration, and embedded diagnostics. The 13.3-inch capacitive touchscreen, extensive connectivity (USB 2.0, Ethernet, HDMI), and optional arbitrary function generator (50 MHz) expand measurement and stimulus capabilities. FastFrame segmented memory acquisition reaches trigger rates exceeding 5,000,000 waveforms/s. Advanced triggering includes edge, pulse width, runt, window, logic, and sequential patterns. Automated measurements span 36 standard parameters with optional mask/limit testing, power analysis, and serial bus decoding (I2C, SPI, I3C, RS-232/422/485, CAN/CAN FD, LIN, FlexRay, SPMI). e*Scope remote viewing enables network-based control and monitoring.
