The Infiniium S-Series is a family of oscilloscopes built around superior signal integrity, combining an advanced time base, a low-noise front end, and a 10-bit ADC technology block. The platform delivers up to 16 bits of resolution, low noise, low jitter, and high ENOB, giving visibility into the true performance of a device under test. The series spans seven bandwidth points from 500 MHz to 8 GHz, with every model providing four analog channels and the choice of a digital-storage (DSO) or mixed-signal (MSO) configuration.

An oscilloscope captures voltage waveforms over time, letting an engineer visualize a signal's amplitude, frequency, timing, and shape. The S-Series is positioned for engineers who must debug a design or verify compliance, where it is critical that the oscilloscope displays a true representation of the signal. It is applied to high-speed serial interface design and validation, jitter characterization, power-integrity analysis, eye-diagram and PAM-3/PAM-4 work, and wideband RF measurements, with a broad suite of high-speed digital debug and design tools.

Listed uses include high-speed serial interface design with the standard Serial Data Analysis software, jitter characterization, power integrity analysis, eye-diagram and mask testing, FPGA debug-port capture, power-rail sequencing, and wideband RF, microwave, and millimeter-wave measurements. The MSO configuration extends this to evaluating control-signal relationships, data buses up to 16 bits wide, and protocol trigger and decode for buses such as I²C, SPI, RS-232, JTAG, and USB. To support those workflows it offers comprehensive signal integrity applications, including setup wizards that walk through each measurement setting, an equalization wizard for opening closed eyes on fast data streams, and a crosstalk analysis application (D9020ASIA) for determining the effects of aggressors on a signal. Jitter tests, eye diagrams, and similar measurements can be configured automatically from the Analyze menu, reducing overall test time.

Brand Heritage

Keysight Technologies traces its test-and-measurement lineage to Hewlett-Packard, whose instrument business was spun off as Agilent Technologies in 1999 and then established as the independent Keysight Technologies in 2014. The Infiniium product name has carried across that history.

Compare Other Models in This Series

The Infiniium S-Series is a single oscilloscope family spanning bandwidths from 500 MHz to 8 GHz, with every model sharing the same core architecture: four analog channels, a 10-bit ADC, a low-noise front end, and the Infiniium user interface on a Windows 10 PC-based platform. Each model is offered in a digital-storage (DSO) or mixed-signal (MSO) configuration, the latter adding 16 digital channels.

Because the models share the platform, the difference between them is primarily headline bandwidth and the corresponding rise-time and ENOB figures, plus the DSO-versus-MSO choice. Bandwidth and MSO functionality can both be added after purchase with a software license key or the N2901E MSO upgrade.

Each new model below is its own dedicated product page with condition-matched pricing. Select the model whose bandwidth and configuration fit your application, then choose the listing that matches the condition you need.

The models differ chiefly by analog bandwidth, which steps from 500 MHz (DSOS054A/MSOS054A) through 1, 2, 2.5, 4, and 6 GHz up to 8 GHz (DSOS804A/MSOS804A). Higher bandwidth corresponds to faster typical 10/90% rise time and a lower full-bandwidth ENOB figure, as shown in the comparison table that follows.

On the 6 GHz and 8 GHz models, the rated bandwidth is supported in two-channel mode; with all four channels active the maximum bandwidth is 4 GHz. DSO models can be upgraded to MSO models, adding 16 digital channels. Refer to the comparison table for each model's bandwidth, rise time, and ENOB values.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Maximum input voltage: 50 Ω path ±5 V; 1 MΩ path 30 VRMS or ±40 VMAX (DC+VPEAK). The included N2873A 10:1 probe supports 300 VRMS or ±400 VMAX (DC+VPEAK). No transient overvoltage is allowed in either the 50 Ω or 1 MΩ path, with or without probes.

Important: 6 GHz and 8 GHz bandwidth is supported only when two channels are active; with all four channels on, maximum bandwidth is 4 GHz (applies to DSOS604A/MSOS604A and DSOS804A/MSOS804A).

Important: The DSA option (DSOS001-DSA) can only be installed on new units. Adding DSA functionality post-purchase (N2113A-200 + D9010JITA) is not the same as the new-unit DSA option and is subject to a support subscription.

Important: DDR3 compliance testing on an S-Series is limited to 1600 MT/s.

Important: All existing DSO models are user-upgradable to MSO with part N2901E; the required upgrade time is less than 5 minutes.

Recommended pairing: use the N7020A or N7024A power rail probe with the D9010POWA Power Integrity application for power-integrity measurement and analysis.

Important: Full-bandwidth ENOB and noise floor figures are typical specifications measured at full bandwidth without high-resolution mode enabled; they are not warranted.

Important: Standard memory depth may vary by specific build date or configuration; the datasheet overview states up to 820 Mpts/ch while the acquisition table lists 800 Mpts maximum - check the instrument's configuration for the installed depth on this unit.

Usage tip: for higher-bandwidth measurements, pair the S-Series with the active InfiniiMax 1130/31/32/34B single-ended or differential probes (1.5–7 GHz) from the supported probe family.
