Tektronix MSO46B 1 GHz — 4 Series B Mixed Signal Oscilloscope
In summary, the Tektronix MSO46B is a 6-channel Mixed Signal Oscilloscope from the 4 Series B platform, configured with 1 GHz of analog bandwidth on 6 FlexChannel® inputs. It delivers a 12-bit ADC (16-bit in High Res mode), 6.25 GS/s real-time sample rate on all channels, 31.25 Mpoints standard record length (62.5 Mpoints optional), and a 13.3-inch optically-bonded 1,920 × 1,080 HD capacitive multi-touch display. Each unit ships with one TPP1000 passive probe per channel. The 4 Series B is the second generation of the 4 Series, with a new processing platform that more than doubles responsiveness and significantly accelerates measurements and data transfers.
What is the Tektronix MSO46B 1 GHz used for?
The MSO46B 1 GHz is used to verify and debug embedded systems, validate power converters, and characterize complex multi-channel designs requiring simultaneous time-domain, frequency-domain, and digital logic visibility. Tektronix identifies the platform as ideal for embedded systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters. FlexChannel® lets each input act as analog, eight digital inputs (with TLP058), or simultaneous analog + spectrum — so the instrument is reconfigurable without buying additional hardware.
How does the 4 Series B compare to a traditional 8-bit oscilloscope?
The 4 Series B uses a 12-bit ADC providing 16× the vertical resolution of traditional 8-bit ADCs, with High Res mode extending to 16 bits at ≤125 MS/s. Lower-noise front-end amplifiers further improve fine-detail resolution — critical for engineers measuring millivolt-level switching ripple on high-voltage rails.
Quantitatively, the MSO46B 1 GHz delivers >500,000 wfms/s standard capture (FastFrame™ to >5,000,000 wfms/s), ≤ 7 ps RMS trigger jitter in sample/edge mode, 36 automated measurements, and an auxiliary trigger input rated ≤ 300 VRMS. Standard 1 MΩ DC gain accuracy is ±1.0% (±2.0% at 1 mV/Div and 500 µV/Div). Time base accuracy is ±2.5 × 10⁻⁶ over any ≥ 1 ms interval. Operating range 0 °C to +50 °C; Measurement CAT II (300 V).
The 4 Series B aligns with standards engineers expect: LXI Core 2016 v1.5; 10/100/1000BASE-T Ethernet; USB 2.0 Host, USB 3.0 SuperSpeed, USB 2.0 Device (USBTMC); the TekVPI® probe interface; IVI-COM drivers for LabVIEW, LabWindows/CVI, MATLAB, .NET, Python, and C/C++/C#; and three-phase harmonics analysis per IEEE-519 via optional 4-3PHASE. Optional three-phase electrical analysis (4-3PHASE) is available on the 6-channel model only. Safety: UL 61010-1, 61010-2-030; CAN/CSA-C22.2 No. 61010.1, 61010.2.030; EN 61010-1; IEC 61010-1, 61010-2-030; CE marked; RoHS compliant.
Why engineers choose the 6-channel 4 Series B
- Six analog channels eliminate the trade-off when debugging multi-rail power converters, three-phase systems, or automotive electronics needing more than four simultaneous analog viewpoints.
- Six-channel models are priced only ~20% above four-channel models — far less than the 50% one might expect — making the extra channels an unusually high-leverage investment.
- Optional 4-3PHASE three-phase electrical analysis is exclusive to the 6-channel model: IEEE-519 harmonics, phasor diagrams, switching ripple, DC-to-three-phase-AC converter measurements (EV/inverter design).
- Digital channels share the same 6.25 GS/s sample rate and up to 62.5 Mpoint record length as analog channels — eliminating the traditional MSO compromise.
- Spectrum View provides independent time- and frequency-domain acquisition paths behind each FlexChannel® — both domains can be optimized simultaneously without the constant tuning of math-based FFTs.
Common applications
- Embedded systems debug — time-correlated analog rails plus I²C, SPI, eSPI, I3C, UART, CAN, CAN FD, LIN, FlexRay, SENT, and other buses (with decode options)
- Switch-mode power supply design — ripple, switching loss, dv/dt, di/dt, SOA, in-rush current, harmonics (4-PWR-BAS / 4-PWR)
- Wide-bandgap (SiC / GaN) validation per JEDEC and IEC using the 4-WBG-DPT Double Pulse Test option, paired with IsoVu™ isolated probes
- Mixed-domain analysis — Spectrum View + RF vs. Time + Spectrograms + IQ capture for noise hunting, EMI investigation, intermittent RF events
- Compliance and production test — Mask/Limit testing (4-MTM), automated pass/fail, bus protocol triggering

Product Core & Specifications
The 4 Series B pairs a 13.3-inch HD optically-bonded display — the largest in its class — with a streamlined front panel: color-coded LED light rings, dedicated Run/Stop, Single Sequence, Force Trigger, Default Setup, Autoset, and Quick-save buttons. Stacked display mode automatically gives each waveform its own graticule slice so every channel uses the full ADC range simultaneously, eliminating the visibility-vs-accuracy trade-off. Variable font sizing (12–20 point) scales the entire UI, and the capacitive touchscreen supports drag, pinch, expand, and swipe gestures.
Behind each FlexChannel®, Tektronix's patented Spectrum View architecture provides both a time-domain decimator and a frequency-domain digital downconverter (DDC). The two acquisition paths run independently, so time-domain settings (sample rate, record length, time/div) and frequency-domain settings (center frequency, span, RBW) can be optimized simultaneously — something math-based FFTs cannot do. Channel Power (CHP), ACPR, and Occupied Bandwidth (OBW) measurements are integrated as standard on each channel.

Probe compatibility & included probes
The instrument uses the TekVPI® probe interface, supporting direct attachment of TekVPI active, differential, and current probes — including TIVP Series IsoVu™ isolated probes — without external power. Up to 80 W is available at the front-panel connectors. Each MSO46B ships with one passive probe per channel matched to model bandwidth: TPP0250 (200 MHz models), TPP0500B (350/500 MHz models), TPP1000 (1 GHz/1.5 GHz models).
Important — Probe Selection: Included passive probes match the configured bandwidth. To realize the full 1 GHz at the probe tip, ensure any connected probe is rated at or above the instrument bandwidth. For low-voltage / low-loading work, the optional TPP0502 (500 MHz, 2× attenuation, 12.7 pF) is recommended. For floating, high-common-mode, or high-voltage differential measurements (inverters, SiC/GaN power, current shunts), the TIVP Series IsoVu™ optically isolated probes are appropriate — up to 1 GHz bandwidth, 120 dB CMRR @ 100 MHz, 2,500 V differential dynamic range, 60 kV common-mode range.
