PNA Series Firmware Upgrades (Includes PNA, PNA-X, and PNA-L)
NOTE: This web page is temporary and will be disabled in mid-2022. All support information has moved to Technical Support under each PNA model number on keysight.com.
If you have not downloaded firmware before, please read the various notes below. If you are familiar with downloading firmware files, then just use the links below. Please save the file to disk before attempting to install it! New firmware releases typically occur in 3-6 month intervals. The dates shown for each firmware revision are the compile dates; not the actual release dates, which may be much later.
Note: Due to production and shipping cycle times, new PNAs will almost always arrive with older firmware. As with many other devices, you should first update the firmware to the latest Customer Release version available here.
1 Production releases are regularly scheduled builds that are installed on all PNAs shipped from the factory. Due to the very long testing process, these releases are relatively infrequent.

Firmware Installation, Notes, and Warnings
Supported Models Note: While older models may be able to use newer firmware, they are not fully supported.
Refer to the PNA Firmware Support Matrix Document. CPU and memory limitations
may adversely affect usability on older hardware when used with newer firmware. There are currently no known issues
that would prevent 7.5x firmware from functioning on PNA models E835xA, E836xA/B or N5230A (XP with 500 MHz CPU).
E880xA models cannot use any firmware above A.06.04.32.
Warning: Installing firmware older than what the PNA was originally shipped with is not warranted and may produce bad data. Occasional hardware changes may necessitate corresponding firmware changes. Installing firmware that is not aware of these changes will cause problems.
Note: Updating of firmware will not invalidate or otherwise affect your annual instrument calibration.
Note: Windows 7 instruments must run firmware A.10.00.xx or higher. Likewise, XP instrument must run firmware A.09.xx.xx or below. There is no version of firmware that will function on both operating systems.
Note: Some new PNAs may be shipped with a higher revision than those shown above. If so, you should not attempt to change the installed firmware.
Note: If using AgileUpdate to download firmware, please be aware that it will only grab the latest Production Releases. If you want to grab the latest Customer Releases, check the 'Customer Release' checkbox (on newer versions of AgileUpdate.)
Installation: If you are downloading directly to the PNA, it is recommended that you save the .msi or .exe firmware file to the directory D:\Updates\Firmware. Once the file is downloaded, simply execute the file by double-clicking on it.
If downloading to a PC, the resulting file should be transferred to the PNA (preferably to D:\Updates\Firmware) and then executed by double-clicking on it. It is not necessary for the firmware file to be located on the PNA. The firmware installation file could reside on a central server or simply remain on a flash drive. As long as the PNA can locate the file using Windows Explorer, the firmware can be installed by simply double-clicking on the file.
Note For Older PNAs; Models E8356A, 57A, and 58A: If the rear panel USB port is oriented horizontally, then you have an older 266MHz CPU board. We strongly recommend that you install 256MB of memory if any firmware revision above 2.62 is desired. While this is not an absolute necessity, performance will be very sluggish without this extra memory. Even with this extra memory, using more than 1601 points will slow the responsiveness of the analyzer. The memory type needed is: 256MB SDRAM SODIMM, PC66 or faster in a 32x64 configuration.
