Keysight PNA Series Hard Disk Drive Part Numbers


Determine Your CPU Board

Keysight has shipped seven different CPU boards with the PNA family over the past twelve years. Each CPU board has different boot-up and hard drive format requirements. So Keysight supplies several hard disk drives which are imaged to work with the various combinations of CPU hardware and Microsoft Windows operating systems. To find the correct hard drive part number, find your CPU board type from this list, then find the hard drive part numbers in the table below.

  • 266 MHz Pentium -- this board has one USB port oriented horizontally and a single GPIB port.
    (Shipped only with the E8356A/57A/58A until February 2002. This board is now obsolete.)
  • 500 MHz Pentium III -- this board has one USB port oriented vertically and a single GPIB port.
    (Shipped on various PNA models from November 2001 to April 2006. This board is now obsolete.)
  • 1.1 GHz Pentium M -- this board has four USB ports and two GPIB ports.
    (Shipped on various PNA models from April 2006 to the present.)
  • 1.6 GHz Pentium M -- PNA-X only. This board has a non-removable internal hard drive.
    (Shipped on the N5241A/42A PNA-X until September 2009. This board is now obsolete.)
  • 2.0 GHz Core Duo -- PNA-X only. This board has an ejectable hard drive.
    (Used on all N5244A/45A/64A models until Nov 2011. Used on N5241A/42A from September 2009 to Nov 2011.)
  • 2.0 GHz i7 -- All N524xA PNA-X and all N522xA PNA from Nov 2011 to Dec 2015. This board has an ejectable hard drive.
  • 1.87 GHz Celeron -- All PNA-L (N5231A thru N5239A) from July 2012. This board has an ejectable hard drive.
  • 2.2 GHz -- All N524xA PNA-X, all N522xA PNA, and all N5231A thru N5239A PNA-L from Dec 2015. This board has an ejectable hard drive.

Determine Your Hard Drive Part Number

From the very first PNA shipped in October 2000 until January 2009 (Sep '09 for some models), PNAs were shipped with PATA (Parallel Advanced Technology Attachment) interface hard drives. These hard drives have become obsolete in the industry, and Keysight is now producing PNAs with SATA (Serial Advanced Technology Attachment) drives. We have a supply of PATA drives to support our RF PNAs which are not easily convertible to the SATA interface.

The table below shows the PATA and SATA part numbers for the various CPU configurations. If the PNA being serviced is an E8356A/57A/58A, E8801A/02A/03A, or N3381A/82A/83A, see note 5 below.

The 266 MHz and 500 MHz CPUs and the Windows 2000 Operating System are no longer supported. Please contact for information on upgrading these systems.

Ordering one of the ten digit part numbers shown here will get you a fully imaged hard drive containing the Windows operating system and the latest PNA firmware. Order one of these parts if you are replacing an identical drive.

The N898xA model numbers shown here should only be ordered when upgrading from one operating system to another. The N8980A/81A/82A, which are now obsolete, were sold as a Windows 2000 to Windows XP upgrade drive. The N8983A/84A are Windows XP to Windows 7 upgrade drives. These include a new Windows Certificate of Authenticity sticker and a fully imaged hard drive mounted in a "cradle" with the necessary interface boards. If you are not upgrading the operating system, order the ten-digit part number shown in the table below for your CPU board.

  1. The N8980A/81A/82A are obsolete. These assemblies were intended for Windows 2000 to Windows XP upgrades. New Windows XP licenses can no longer be sold.
  2. The E8801-60070 and N5242-60035 are no longer orderable from Keysight. Contact to determine possible alternatives if a replacement hard drive is required.
  3. The E8364-60192 and N5230-60050 are under inventory control. These drives may be restricted to those customers who have already purchased extended support contracts. If you require a replacement for a PATA drive, you will need to order the applicable SATA hard drive part number and the N5230-60052 hard drive carrier kit. This kit contains a collection of all the parts required to assemble the hard drive carrier for the SATA drive. Please note that the N5230-60052 will not work with a PATA drive.
  4. This solid state drive includes (and is already mounted to) the slide-out drawer that fits into the CPU assembly.
  5. The part numbers in the columns for the 500MHz and 1.1GHz CPUs apply to PNA models E836xA/B/C and N5230A/C. PNA models E8356A/57A/58A, E8801A/02A/03A, and N3381A/82A/83A can not be converted to use a SATA drive. Contact to determine if a replacement PATA hard drive is available.
  6. The hard disk drive (HDD) or solid state drive (SSD) capacities shown above are for those drives which ship today. This capacity will change as the industry continues to evolve. Keysight Technologies reserves the right to change the drive capacity at any time without notice.

Other Alternatives

An ESATA HDD adapter tray is available for the N524xA/B PNA-X models with CPU Version 5, 6, or 7, the N522xA/B PNA models, and the N5231A/B-N5239A/B PNA-L models. The part number is W1312-60070. See our security web page for more information.
