Overview

In summary, the Tektronix MSO66B-6-BW-1000 is a 6-channel mixed signal oscilloscope with 1 GHz of analog bandwidth, a 12-bit ADC (extended to 16 bits in High Res mode), a 15.6-inch 1920×1080 capacitive touchscreen, and FlexChannel® inputs that let each channel be used as one analog input or eight digital logic inputs. It is part of the Tektronix 6 Series B MSO family — the current flagship mid-range Tektronix platform — designed for embedded systems debug, power electronics, high-speed serial validation, three-phase power analysis, and RF-adjacent mixed-domain work.

What is the Tektronix MSO66B-6-BW-1000 used for?

The MSO66B-6-BW-1000 is used to capture, visualize, and analyze time-domain and frequency-domain signals on electronic systems with clock speeds and bus rates up to 1 GHz. Typical applications include embedded firmware and hardware debug across I²C, SPI, UART, CAN/CAN FD, LIN, FlexRay, USB 2.0, Ethernet, and MIPI buses; switching power supply and three-phase inverter characterization; DDR3/LPDDR3 memory debug and compliance; PAM3 and high-speed serial signal-integrity analysis; and Spectrum View frequency-domain analysis on every analog input.

Why choose a 6-channel oscilloscope?

6 analog channels lets you observe more nodes of a system at once without the trigger-alignment and documentation overhead of running two scopes in parallel. Three-phase power conversion, polyphase motor drives, multi-rail power integrity, and complex embedded systems frequently require simultaneous observation of more than four analog signals to verify and characterize device performance. Per Tektronix, six-channel models typically cost only about 25% more than four-channel models, and eight-channel models about 67% more — far less than the doubling that older single-purpose channel-count economics would imply.

MSO66B-6-BW-1000 specifications at a glance

Analog bandwidth is 1 GHz on all analog channels, with a 12-bit ADC that delivers 16 times the vertical resolution of traditional 8-bit oscilloscopes. Real-time sample rate is 50 GS/s on 2 channels, 25 GS/s on 4 channels, and 12.5 GS/s on more than 4 channels; this 6-channel configuration tops out at 12.5 GS/s when all channels are active. Standard record length is 62.5 Mpoints on every channel, expandable to 1 Gpoint per channel as an option. Random noise is specified as low as 51.8 µV RMS at 1 mV/div with 1 GHz bandwidth — among the lowest in this class — enabled by the TEK061 front-end ASIC. Waveform capture rate exceeds 500,000 wfms/s in Peak Detect / Envelope modes.

How does the MSO66B-6-BW-1000 fit modern compliance and industry standards?

The 6 Series B MSO platform supports automated TekExpress compliance test solutions for USB 2.0, Ethernet (10/100/1000BASE-T and 2.5/5/10GBASE-T), Automotive Ethernet (100BASE-T1, 1000BASE-T1, 10BASE-T1S, 10BASE-T1L), MIPI D-PHY 1.2, and DDR3/LPDDR3, with calibration data documenting traceability to National Metrology Institutes and ISO 9001 / ISO/IEC 17025 quality system registration. Option 6-SEC adds password-protected I/O lockdown and BIOS protection developed in compliance with NISPOM DoD 5220.22-M Chapter 8 — important for classified and controlled-environment labs. The instrument is LXI Core 2011 compatible and supports IVI-COM drivers, TekVISA, USBTMC, and LAN/USB programmatic control.

How does the MSO66B-6-BW-1000 compare with prior generations, and where does it fit in a typical lab?

Against the prior Tektronix DPO7000C and MSO/DPO70000C platforms, the 6 Series B improves most on noise floor and channel architecture. At 1 GHz / 10 mV/div, typical 50 Ω input-referred noise is 82.9 µV RMS versus 279 µV RMS on the DPO7000C — roughly 3.4× better. At 4 GHz / 100 mV/div, noise is 1.73 mV RMS versus 4.3 mV RMS on the MSO/DPO70000C. FlexChannel® inputs replace fixed analog/digital channel allocation: each input carries one analog, eight digital (TLP058), or a simultaneous spectrum view, in any combination. Vertical resolution is 12-bit native (16-bit in High Res) versus 8-bit on legacy platforms. Typical workloads include embedded debug across I²C, SPI, I3C, UART, CAN/CAN FD, LIN, FlexRay, USB 2.0, eUSB2, and SPMI; power-electronics analysis with 6-PWR; three-phase work with 6-IMDA (MSO66B / MSO68B only); high-speed serial validation with 6-DJA; and mixed-domain RF work using Spectrum View on every channel.

Accessories Supplied

Each new instrument ships with one TPP1000 1 GHz passive voltage probe per FlexChannel® input (high dynamic range, 3.9 pF capacitive loading), a front cover with integrated accessory pouch, a USB mouse, a country-specific power cord (selected at order via the A0–A99 option codes), an installation and safety manual in English, Japanese, and Simplified Chinese, the embedded context-sensitive help system, and a calibration certificate documenting traceability to National Metrology Institute(s) under Tektronix's ISO 9001 and ISO/IEC 17025 registered quality system. The standard one-year warranty covers all parts and labor on both the instrument and the included probes.

Product Core & Specifications

Bandwidth is the single most important specification on any oscilloscope: capturing clean square-wave edges requires capturing the harmonics at 3×, 5×, and 7× the fundamental. The MSO66B-6-BW-1000 delivers 1 GHz of analog bandwidth across all 6 channels, and bandwidth is field-upgradeable to higher tiers with only a software license and a new front-panel label.

Sample rate on the 6 Series B is tiered by active channel count: 50 GS/s on two channels, 25 GS/s on four channels, and 12.5 GS/s on more than four. In this 6-channel configuration, the architecture supports 12.5 GS/s when all channels are active. Standard record length is 62.5 Mpoints on every channel; Capture Duration = Memory ÷ Sample Rate, so even the standard memory captures several milliseconds at full rate. Customers running long compliance sequences, power-supply startup analysis, or rare-event capture should add 6-RL-1 / -2 / -3 / -4 to extend record length up to 1 Gpoint per channel.

Where the 6 Series B genuinely differentiates is noise performance and channel architecture. The TEK061 front-end ASIC delivers as low as 51.8 µV RMS at 1 mV/div / 1 GHz — roughly 3× lower than the prior DPO7000C generation — and FlexChannel® inputs let every channel be used as one analog signal, eight digital logic inputs (with TLP058 probe), or a simultaneous analog + Spectrum View pair with independent time- and frequency-domain controls.

Core Specifications

Digital Channels (with optional TLP058 logic probe)

Each TLP058 logic probe adds 8 digital inputs (D7–D0) at the cost of one analog channel, allowing this 6-channel model to scale up to 48 digital channels with the right probe complement. Maximum input toggle rate is 500 MHz, with a minimum detectable pulse width of 1 ns (typical). Threshold range is ±40 V in 10 mV resolution; accuracy is ±[100 mV + 3% of threshold setting] after calibration. Typical input dynamic range is 30 V p-p for F_in ≤ 200 MHz and 10 V p-p above 200 MHz; absolute maximum input voltage is ±42 V peak. Probe loading is 2 pF / 100 kΩ (typical).

Trigger System

Trigger modes are Auto, Normal, and Single. Coupling supports DC, HF Reject (attenuates >50 kHz), LF Reject (attenuates <50 kHz), and Noise Reject. Standard trigger types include Edge, Pulse Width, Runt, Timeout, Window, Logic, Setup & Hold, Rise/Fall Time, Parallel Bus, Sequence, and Visual Trigger; Video (optional 6-VID) and RF Magnitude / Frequency vs. Time (optional 6-SV-RFVT) are also available. Auxiliary trigger input accepts ≤5 V RMS into 50 Ω at 400 MHz (Edge trigger only). Holdoff range is 0 ns to 10 s. Typical trigger jitter is ≤1.5 ps RMS in Sample-mode edge triggering, ≤2 ps RMS in FastAcq edge mode, and ≤80 ps p-p for non-edge trigger types. An 8-digit trigger frequency counter is included free with product registration.
