Previous PNA Series Firmware Upgrades

Generally, only the latest firmware should be used on the PNA. However, if you really need a previous firmware revision, they are located in the linked directory on the right. If the firmware you need is not listed, contact us. To download the firmware, just right-click on the file and save it to some convenient location on the PNA, such as in D:\Upgrades\Firmware. After it has been stored, double-click to install. Make sure you read the warning notes below.

Warning: Never try to install any revision A.02.xx on the E8361A or on any model that has a "B" suffix (e.g. E8364B). If this is done, the PNA will no longer function. No damage will occur, but the unit will not function again until firmware A.03.xx or higher is re-installed.

Warning: Never ever try to install revision A.01.60 on anything other than an E8356A, E8357A, or E8358A. Attempting to do this on any microwave instrument will cause major damage (data corruption) which can only be repaired at the factory.

Warning: Any 5.xx revision is only for 4 port models. Revision 6.xx or higher is for 2 or 4 port models.
