In summary, the Tektronix TBS2074B is a 70 MHz, 4-channel digital storage oscilloscope from the TBS2000B Series, built around a 9-inch WVGA color display, a 2 GS/s maximum sample rate, and a 5 million-point record length on every channel. It is part of the Tektronix TBS (Tektronix Basic Scope) entry-tier family, positioned for benchtop debug, embedded development, education, and routine production test where a benchtop scope must deliver reliable measurements at an accessible price point. ### What is the Tektronix TBS2074B used for? The TBS2074B is used for general-purpose oscilloscope work on embedded systems, low- to mid-frequency analog circuits, switch-mode power supply analysis, classroom and laboratory instruction, and incoming inspection of electronic assemblies. With 4 channels at 70 MHz, it covers the day-to-day waveform-capture, timing-verification, and signal-integrity sanity checks that dominate the electronics bench. ### Who buys the TBS2074B, and why this bandwidth? Typical buyers include hardware engineers debugging microcontroller-based designs (SPI, I²C, UART at logic levels), university and community college electronics programs, manufacturing test technicians, and field engineers needing a dependable second scope. The 5× bandwidth rule suggests 70 MHz is appropriate for signals with fundamentals up to roughly 14 MHz; for faster digital edges or RF work, the higher-bandwidth siblings in the series (or the Tektronix 2 Series MSO) are the natural step up. On the measurement side, the TBS2074B delivers a 5 M-point record length on every channel and a 2 GS/s peak sample rate, giving a sustained capture window suitable for both short transient events and longer time-base inspections of supply rails. The vertical system provides 8-bit resolution, 1 MΩ / 13 pF input impedance, ±2% DC gain accuracy from 10 V/div through 5 mV/div, and 20 MHz hardware bandwidth limiting. Peak Detect captures glitches as narrow as 3.5 ns at all sweep speeds, and Average mode supports 2 to 512 waveforms for noise reduction. The TBS2000B Series is manufactured by Tektronix, a brand whose oscilloscopes are operated under ISO 9001 quality system registration and tested in ISO-registered facilities. The TBS2074B ships with a Certificate of Calibration Standard documenting traceability to National Metrology Institute(s), is rated to UL61010-1 and CAN/CSA-C22.2 No. 61010-1 for product safety, complies with EC Directive 2014/30/EU for electromagnetic compatibility, and is backed by a five-year warranty on parts and labor (excluding probes). ## Accessories Supplied Item Description Passive probes 4 × TPP0100 passive voltage probe (one per analog channel — 70 MHz, 10x, BNC interface) Compliance and Safety Instructions Part 071-3635-xx Programmer manual Part 077-1149-xx (PDF, available on tek.com) Power cord Region-specific (see Power plug options) Calibration certificate Documenting traceability to National Metrology Institute(s) and ISO 9001 quality system registration Warranty Five-year warranty covering all parts and labor (excluding probes) ## TBS2074B Core Capabilities The TBS2000B family is Tektronix’s benchtop entry-tier oscilloscope line, replacing earlier TBS1000 and TDS2000 instruments with a markedly larger 9-inch display, deeper memory, and the same TekVPI® probe interface used on higher-end Tektronix scopes. Front-panel knobs are dedicated per channel, and the HelpEverywhere system provides context-sensitive on-screen guidance. Acquisition modes on the TBS2074B include Sample, Peak Detect (3.5 ns glitch capture), Averaging (2 to 512 waveforms), Hi-Res, and Roll (for sweep speeds ≤ 40 ms/div, or 400 ms/div at 20 M record length). Waveform math supports Add, Subtract, Multiply, and FFT (Rectangular, Hamming, Hanning, or Blackman-Harris windows; linear RMS or dBV RMS magnitude). Search and Mark steps through every event matching a user-defined criterion. ### Model Overview — TBS2000B Series Model Channels Bandwidth Max Sample Rate Record Length TBS2072B 2 70 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points TBS2074B 4 70 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points TBS2102B 2 100 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points TBS2104B 4 100 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points TBS2202B 2 200 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points TBS2204B 4 200 MHz 2 GS/s (half) / 1 GS/s (all) 5 M points ### Vertical System — Analog Channels Parameter Value Hardware bandwidth limit 20 MHz, typical Input coupling DC, AC, or GND Input impedance 1 MΩ ± 1%, 13 pF ± 1.5 pF Input sensitivity range 2 mV/div to 10 V/div Vertical resolution 8 bits Maximum input voltage (1 MΩ) 300 V RMS with peaks ≤ ±450 V DC gain accuracy ±2% (10 V/div through 5 mV/div); ±3% typical at 2 mV/div Vertical position range ±5 divisions Common-mode rejection ratio (CMRR), typical 100:1 at 60 Hz, reducing to 10:1 with a 50 MHz sine wave Channel-to-channel isolation ≥100:1 at ≤70 MHz Analog bandwidth (DC coupled) DC to ≥70 MHz ### Horizontal System Parameter Value Max duration at highest sample rate (all channels) 5 ms Time base range TBS220x: 1 ns/div to 100 sec/div; TBS207x / TBS210x: 2 ns/div to 100 sec/div Time-base delay range −15 divisions to 5000 s Deskew range ±100 ns Time base accuracy ±25 ppm over any ≥1 ms interval ### Trigger System Parameter Value Trigger modes Auto, Normal, and Single Trigger holdoff range 20 ns to 8 s Trigger types Edge, Pulse Width, Runt Trigger coupling (analog channels) DC, Noise Reject, High Freq Reject, Low Freq Reject Edge-trigger sensitivity (DC coupled) 0.4 division on the TBS2074B Trigger level ranges Input channels: ±4.90 divisions from center screen ### Waveform Measurements and Math Cursors: Time, amplitude, and screen. **32 automated measurements**, of which up to six can be displayed on-screen simultaneously.
