PNA Series Firmware Upgrades
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.
Hint: If your PNA has Internet access, the easiest and preferred method for updating firmware is to use the PNA's AgileUpdate utility. On the PNA application, click on (Utility), System, Service, AgileUpdate.
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.
Note: Updating of firmware will not invalidate or otherwise affect your annual instrument calibration.
Warning! Attempting to install a 4.xx, 5.xx, or 6.xx revision of firmware on a PNA that currently has revision 1.xx or 2.xx could make the PNA malfunction. It is best to only upgrade to the next sequential major revision. e.g. If you have Rev 1.xx, first upgrade to rev 2.xx, then upgrade to rev 3.x, then 4.xx., and finally 6.xx (5.xx is only for 4-port units.)
Note: Windows 7 instruments must run firmware A.10.00.xx or higher. Likewise, XP instrument must run firmware of A.09.xx.xx or below. There is no version of firmware that will operate 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.)
Warning: Only install firmware on a PNA. Do not attempt to install firmware on a PC as this may render it unusable!
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.
