Enabling Research at the Cutting Edge of Physics

Keysight has engineered the Infiniium 90008 Series oscilloscope/digitizers to meet your most demanding requirements by delivering the features you need to ensure fast and reliable measurements every time:

  1. Unmatched real-time measurement accuracy
  2. Fast offload speeds and compatibility with industry standard computation packages
  3. Powerful internal capabilities with dual on-board PCs and off-the-shelf software

Unmatched Real-Time Measurement Accuracy

Industry’s lowest noise floor: To enable our DSO90008 Series digitizers to operate at high frequencies with minimal electromagnetic interference (EMI) we relied on our expertise in radio frequency (RF) technology. Keysight invested in key technology blocks like our proprietary Faraday caged front end to deliver the lowest noise floor in the industry for the most accurate measurements available.

Precision time base

Each bank of four digitizers has a precision crystal-controlled time base. Sample rates can be selected, in a 1, 2, 2.5 4, 5 sequence, from 10 S/s to 40 GS/s. An internal trigger time interpolator (TTI) with high timing resolution is used to assist with trigger time measurements and positioning with respect to the internal clock (sampling time). The digitizers can also be locked to an external 10 MHz reference. The digitizers feature a sequence acquisition mode that allows the capture and storage of consecutive “single” waveforms. In segmented memory mode the acquisition memory is divided into segments. Waveforms are stored in successive memory segments as they arrive based on a trigger event. The memory can be divided into any number of segments between 2 and 130,000, with segment lengths from 16 points up to 0.5 G points (depending on installed memory). Sequence acquisition mode is extremely useful in almost all impulse-response type applications such as radar, sonar, lidar, time-of-flight, ultrasonics, medical and biomedical research.

Full bandwidth probing and accurate de-embedding and equalization software

The performance of Keysight’s oscilloscopes is matched by the superiority of our probing, de-embedding and equalization offerings. Maintain full bandwidth performance to the probe tip with our InfiniiMax probing solutions, including SMA cables and high temperature probes. Equalize waveforms with our hardware accelerated N5465A InfiniiSim Waveform Transformation Toolset. Configurable system modeling allows you to remove the deleterious effects of unwanted channel elements, simulate waveforms with channel models inserted, view waveforms in physically unprobeable locations, and compensate for loading of probes and fixtures. The N5461A Serial Data Equalization software allows you to model equalization techniques in real time.

Multi-module synchronization

Each module contains 2 independently synchronized 4-channel digitizers. If morethan four synchronous data acquisition channels are required, multiple digitizers can be combined in one of two ways. The first is to utilize the auxiliary trigger in and trigger out, which provides time correlation and synchronization up to 30 ns. Multiple channel synchronization to sub pico second accuracy for five and more channels may be achieved by providing a distributed trigger signal to the aux trigger of each bank of four channels. Multiple modules canbe connected in either fashion enabling hundreds of 40 GSa/s time-correlated channels.

Fast offload speeds and compatibility with industry standard computation packages

The memory and acquisition controller component of our acquisition system is a digital CMOS integrated circuit. A high-speed data demultiplexer with on-board memory, it is designed to capture and memorize 8-bit digital data, at speeds of up to 40 GSa/s. The DSO90008A series digitizers have provisions for of up to 1 Gpt per channel of acquisition memory. Remote and offload access through 10/100/1000 BaseT LAN interface with Web-enabled connectivity using ultra-responsive Ultra VNC. GPIB over LAN provides remote measurement. LXI class C compliant. A USB 2.0 device port lets you control the scope and transfer data via USB 2.0.

Offload data for custom analysis on your PC using an optional high-speed PCIe bus card available through to transfer data at sustained rates up to 150 MB/s. Device drivers for VxWorks, LabVIEW RT, and Linux, with application code examples for MATLAB, C/C++, Visual Basic, LabVIEW, and LabWindows/CVI come standard.

Powerful on board capabilities with dual PCs and off-the-shelf software

Each 8 channel module boasts two PCs that run application software and provide standard I/O functionality. In addition, custom IDA (Infiniium Data Accelerator) hardware on the acquisition boards speeds measurements requiring filtering and math algorithms. Packed with numerous general-purpose measurements and analysis features, Infiniium 90008 Series oscilloscope/digitizers can also be outfitted with a number of unique software options. Supported application packages can speed scientist’s insight into research questions. Key software options are listed on the following pages. For a complete list of supported software visit
