The Agilent Infiniium 9000 Series is a family of mixed-signal and digital storage oscilloscopes engineered for the broadest measurement capability across hardware design, debug, and compliance test workflows. The series spans four bandwidth tiers — 600 MHz, 1 GHz, 2.5 GHz, and 4 GHz — with each model available as a DSO (four analog channels) or MSO configuration adding sixteen high-speed digital channels. All models share a common platform: a 15-inch XGA touchscreen display, a 9-inch deep chassis, 26 lb weight, and Windows-based operation with standard USB, LAN, and DVI/XGA video output.

Engineers use Infiniium 9000 Series oscilloscopes for hardware design and debug, embedded systems development, serial bus analysis, and compliance testing against industry standards. The datasheet identifies application coverage including I2C and SPI bus debug, RS-232/UART decode, CAN/LIN/FlexRay automotive bus analysis, USB 2.0 compliance, DDR1/DDR2/DDR3 and LPDDR memory characterization, Ethernet compliance, MIPI D-Phy validation, PCI Express analysis, SATA testing, JTAG scan chain decode, and jitter analysis with the EZJIT, EZJIT Plus, and EZJIT Complete software families. FPGA developers can use the dynamic probe application for Altera and Xilinx internal-signal visibility.

Brand Heritage

Agilent Technologies was spun off from Hewlett-Packard in 1999, inheriting HP's test and measurement business including the Infiniium oscilloscope platform. In 2014, Agilent's electronic measurement division was separated into a new company, Keysight Technologies, which now holds the Infiniium product line. Instruments sold under the Agilent brand — including the Infiniium 9000 Series — are supported through Keysight's service infrastructure.

Compare Other Models in This Series

The Infiniium 9000 Series is a single oscilloscope platform offered across four analog bandwidth tiers — 600 MHz, 1 GHz, 2.5 GHz, and 4 GHz — with each tier available in DSO (four analog channels) and MSO (four analog plus sixteen digital channels) configurations. All eight models share the same chassis dimensions, the same 15-inch XGA touchscreen, the same Windows-based operating system, the same I/O ports, and the same software application ecosystem. The differences between models are bandwidth, maximum sample rate at the lower bandwidth tier, and the inclusion of digital channels on MSO variants.

Because the platform is shared, an Infiniium 9000 Series oscilloscope at any bandwidth tier supports the same advanced triggering, the same segmented memory architecture, the same protocol decode software options, and the same compliance application suite. Selecting between models is primarily a matter of matching the oscilloscope's analog bandwidth and sample rate to the highest signal frequencies present in the device under test, and deciding whether the integrated logic analysis of the MSO configuration is required for the application.

The DSO9104A / MSO9104A occupies the 1 GHz position in the Infiniium 9000 Series. At this bandwidth tier, the oscilloscope delivers 20 GSa/s maximum real-time sample rate in 2-channel mode (10 GSa/s in 4-channel mode), with a typical rise time of 253 ps (10%–90% at 50 Ω). This model is the entry point in the series for high-speed USB 2.0 compliance testing, which the datasheet identifies as supported on 2.5 GHz and higher models for high-speed USB but supported on the 1 GHz analog channels for low- and full-speed USB.

Bandwidth and sample rate are the primary differentiators across the Infiniium 9000 Series. The 600 MHz models (DSO9064A / MSO9064A) provide 10 GSa/s in 2-channel mode and 5 GSa/s in 4-channel mode. The 1 GHz, 2.5 GHz, and 4 GHz models all share the same 20 GSa/s / 10 GSa/s sample rate architecture, with the bandwidth specification driving the analog front-end design and rise-time performance. Typical rise times documented in the datasheet are 540 ps on the 600 MHz model, 253 ps on the 1 GHz model, 142 ps on the 2.5 GHz model, and 85 ps on the 4 GHz model.

Software application compatibility varies by bandwidth tier. The datasheet notes that USB 2.0 compliance testing is supported on 2.5 GHz and 4 GHz models, MIPI D-Phy serial decode requires the 4 GHz analog channels, PCI Express serial trigger and protocol viewer requires the 4 GHz model, and SATA triggering and decode requires the 4 GHz model. All other documented software options — including I2C/SPI, RS-232/UART, CAN/LIN/FlexRay, JTAG, low/full-speed USB, EZJIT family jitter analysis, InfiniiScan, and the DDR memory compliance applications — are supported across all four bandwidth tiers. See the comparison table below for the full bandwidth, sample rate, and channel configuration of each model in the series.
