Which modular mainframes in this range require an external display?

The Keysight Technologies (Agilent HP) 16700A and 16700B both require an external monitor for user operation. In contrast, the 16702A, 16702B, 16902A, and 16903A mainframes feature integrated color touchscreens.

Can I expand the physical slot capacity of a 16700-series mainframe?

Yes. The Keysight Technologies (Agilent HP) 16700B mainframe supports the connection of one 16701B expansion frame, which adds 5 additional measurement slots. Similarly, the 16700A supports the 16701A expansion frame.

What is the difference in state clock rate between the 16910A and 16950A modules?

The 16950A module provides a higher maximum state clock rate of 600 MHz (with an 800 Mb/s data rate). The 16910A module has a base state clock rate of 250 MHz, which can be upgraded to 450 MHz with Option 500.

Modular Mainframe Architectures: 16700 vs. 16900 Series

Keysight's modular logic analysis mainframes are designed to hold multiple acquisition and stimulation cards, allowing synchronized, multi-channel testing across different buses.

16700 Series (HP-UX Platform): The 16700 Series utilizes the HP-UX operating system and PA-RISC or Motorola PowerPC processors. The Keysight Technologies (Agilent HP) 16700A and Keysight Technologies (Agilent HP) 16700B both offer 5 measurement slots but require an external monitor for operation. The 16700B features a 150 MHz PA-RISC processor, an 18 GB hard drive, and supports adding a 16701B expansion frame to double slot capacity. For integrated displays, the Keysight Technologies (Agilent HP) 16702A features a 9.1-inch color resistive touchscreen, while the Keysight Technologies (Agilent HP) 16702B upgrades the user interface to a 12.1-inch color touchscreen and runs on a Motorola PowerPC processor.
16900 Series (Windows Platform): The 16900 Series transitions to a Windows XP Professional platform with an open PCI bus architecture. The Keysight Technologies (Agilent HP) 16903A is a compact 3-slot mainframe featuring an integrated 12.1-inch SVGA touchscreen and support for up to four external monitors. For larger configurations, the Keysight Technologies (Agilent HP) 16902A expands capabilities to 6 module slots, providing a larger overall footprint while maintaining the same 12.1-inch touchscreen, front-panel knobs, and Windows-based setup.

Portable Benchtop Logic Analyzers

For applications requiring a self-contained instrument rather than a modular chassis, portable systems provide a fixed channel and probing setup.

The Keysight Technologies (Agilent HP) 16802A is a portable logic analyzer with 68 total channels (64 data channels and 4 clock/qualifier channels). It features an integrated 15-inch color touchscreen and operates on Windows XP Professional (or Windows Embedded Standard 7 in updated versions). The 16802A provides up to 4.0 GHz timing zoom (250 ps resolution) with a 64K sample memory per channel. Standard state clock speeds reach 250 MHz, which can be upgraded to 450 MHz with Option 450.

State and Timing Acquisition Modules

Modular mainframes rely on plug-in cards to define performance specifications like channel counts and memory depth.

Keysight Technologies (Agilent HP) 16950A: This high-performance module for the 16900 Series provides 68 channels. It delivers a state clock rate of 600 MHz and a maximum state data rate of 800 Mb/s. It features a 4 GHz timing zoom with a 64K sample depth, and standard acquisition memory configurations range from 256K samples up to 16M samples (via Option 016).
Keysight Technologies (Agilent HP) 16910A: Designed for higher channel-density requirements, this module provides 102 channels. It runs state analysis up to 250 MHz on base models (Option 250) and up to 450 MHz when upgraded (Option 500). It shares the same 4 GHz timing zoom capability as the 16950A but offers memory expansion up to 32M samples.

Stimulus and Pattern Generation

In addition to capturing data, these systems can generate digital patterns to simulate missing components or stimulus signals.

The Keysight Technologies (Agilent HP) 16522A is a 200 MHz digital pattern generator module. It is compatible with HP/Agilent 16500B, 16500C, and 16700-series mainframes. This single-slot module provides 20 channels at a 200 MHz clock rate, or 40 channels when configured for a 100 MHz clock rate, with a memory depth of 258,048 vectors per channel.
