PNA Series Previous Firmware



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.

We only list the last version of any given firmware series. These are the only versions that should be used. They will behave the same as prior versions in the same series, but they have more bugs fixed. Use of older firmware in any given series is NOT recommended! If you really really need a version other than what is listed here, please contact us.

Firmware Warnings and Restrictions

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.

Warning: Installation of firmware older than what the instrument was shipped with is not recommended as the PNA may have newer hardware than older firmware may not be aware of.
