z3985 Embedded Controller

Embedded Controller for 3U PXI™ Express Systems

The z3985 Embedded Controller, based on the fourth generation Intel Core i7 processor, is specifically designed for hybrid PXI Express-based testing systems, delivering maximum computing power for a wide variety of test and measurement applications.

Combining state-of-the-art 2.4 GHz quad-core Intel Core i7-4700EQ processors (3.4 GHz maximum in single-core, Turbo Boost mode), and 16 GB of 1600 MHz DDR3L memory, the z3985 utilizes four separate computing engines on a single processor, enabling execution of numerous independent tasks simultaneously in a multi-tasking environment. With a configurable PCIe switch, the z3985 can support four links x4 or two links x16 and x8 PXI Express link capability, with maximum system throughput of up to 8 GB/s.

The LitePoint z3985 Embedded Controller provides ample front-panel interface options for hybrid PXI-based test systems control including:

  • 2 DisplayPort connectors allowing connection to 2 monitors
  • Dual USB 3.0 connections for high speed peripheral devices
  • 4 USB 2.0 ports for peripheral devices and USB instrument control
  • Dual Gigabit Ethernet ports for LAN connections and controlling LXI instruments
  • Micro-D GPIB connector for GPIB instrument connection
