Keysight Technologies 1000 X Series Low-Cost 4-Channel Oscilloscope

Overview

The Keysight Technologies 1000 X Series is a purpose-engineered 4-channel digital oscilloscope designed for educational laboratories, entry-level R&D environments, and service technicians requiring professional-grade signal acquisition capabilities at an accessible price point. Built upon proven architecture derived from Keysight’s higher-tier InfiniiVision platforms, the 1000 X Series delivers industry-relevant performance without compromise in core measurement fidelity. Its real-time sampling engine operates at 2 GSa/s (giga-samples per second) across all analog channels simultaneously—enabling accurate reconstruction of fast-edged digital signals, transient anomalies, and high-frequency modulation components. The instrument employs Keysight’s proprietary MegaZoom IV ASIC, which sustains a waveform update rate of up to 50,000 waveforms per second—a critical advantage when capturing low-probability events such as intermittent glitches, setup/hold violations, or power-supply rail droop. Unlike basic oscilloscopes relying on segmented memory or reduced processing throughput, the 1000 X Series maintains full acquisition depth and trigger responsiveness under continuous operation, ensuring deterministic visibility into signal behavior over extended observation windows.

Key Features

• Four fully isolated analog input channels with 200 MHz bandwidth (standard configuration), supporting differential probing and math-based channel arithmetic (add, subtract, multiply, FFT).
• Integrated 4-channel logic analyzer capability with configurable thresholds and protocol-aware triggering for SPI, I²C, UART, and CAN (with optional firmware activation).
• Six-in-one instrument functionality: oscilloscope, function/arbitrary waveform generator (20 MHz output), frequency counter, digital voltmeter (DVM), spectrum analyzer (via FFT-based Bode plot generation), and protocol decoder—all accessible from a unified interface.
• LAN-based remote control via standard web browser (HTML5-compliant), supporting concurrent multi-user access with role-based session management—ideal for university teaching labs and distributed engineering teams.
• Advanced measurement suite including 24 automated parametric measurements (Vpp, rise time, jitter, duty cycle, etc.), gated FFT for localized spectral analysis, and pass/fail template testing compliant with IPC-9592 and MIL-STD-704 power integrity verification workflows.

Sample Compatibility & Compliance

The 1000 X Series supports passive and active probes rated for ≤300 MHz bandwidth and 10:1 / 1:1 attenuation ratios. Input impedance is configurable between 1 MΩ || 15 pF and 50 Ω termination modes, accommodating both high-impedance circuit node probing and 50 Ω RF signal path characterization. All firmware and calibration procedures adhere to Keysight’s ISO/IEC 17025-accredited metrology framework. The instrument complies with CE, FCC Part 15 Class B, and RoHS directives. Remote operation protocols conform to IEEE 488.2 (SCPI) and LXI Class C specifications, enabling seamless integration into automated test systems governed by IEC 61508 functional safety requirements or FDA 21 CFR Part 11–aligned validation protocols where audit trails and user authentication are mandated.

Software & Data Management

Instrument control and data export are supported through Keysight’s free PathWave BenchVue software (v5.3+), which provides drag-and-drop test sequencing, automated report generation (PDF/CSV), and cloud-synced configuration storage. Raw waveform data can be exported in MATLAB (.mat), CSV, or binary formats with full timestamping and metadata embedding (channel scaling, trigger position, acquisition mode). Firmware updates are delivered via signed package files verified using SHA-256 checksums and X.509 certificate chains—ensuring integrity during field deployment. Audit logs record all user-initiated actions (e.g., parameter changes, file saves, remote connections), supporting GLP/GMP documentation requirements in regulated industries.

Applications

• Undergraduate electronics laboratories: Teaching fundamental concepts including Nyquist sampling theory, aliasing effects, Fourier decomposition, and serial bus timing analysis.
• Embedded systems validation: Debugging microcontroller peripheral interfaces (SPI clock skew, I²C arbitration loss, UART framing errors) with hardware-synchronized decode overlays.
• Power electronics characterization: Measuring switching losses in MOSFET/IGBT gate drivers, ripple analysis on DC-DC converter outputs, and harmonic content evaluation via gated FFT.
• Industrial maintenance: Verifying sensor signal integrity (4–20 mA loops, thermocouple outputs), diagnosing EMI-induced noise coupling, and validating programmable logic controller (PLC) I/O timing margins.
• Research prototyping: Rapid iteration of analog front-end designs, filter response verification using built-in Bode plot mode, and stimulus-response analysis of op-amp circuits.

FAQ

Does the 1000 X Series support USB device connectivity for saving waveforms or updating firmware?
Yes—it features a rear-panel USB 2.0 host port for connecting flash drives and a front-panel USB device port for PC communication via NI-VISA or Keysight IO Libraries Suite.
Can the integrated function generator output arbitrary waveforms?
It supports standard waveforms (sine, square, triangle, ramp) and user-defined arbitrary waveforms up to 16 kpts, loaded via BenchVue or direct SCPI command.
Is deep memory upgrade available for extended timebase capture?
No—the instrument uses fixed 2 Mpts acquisition memory per channel; however, MegaZoom IV ASIC optimization ensures no dead time between acquisitions even at maximum memory depth.
Are probe compensation accessories included with purchase?
A set of four 10:1 passive probes (N2861B) and probe compensation tool are supplied standard with each unit.
How is calibration traceability maintained across the product lifecycle?
Each unit ships with a NIST-traceable calibration certificate valid for one year; Keysight-certified calibration services follow ANSI/NCSL Z540-1 and ISO/IEC 17025 standards.
