RF Network Analyzers Upgrading or Re-Installing Firmware
Service Guide 8-5
Upgrading or Re-Installing Firmware
Firmware is contained on two high-density floppy disks which are in DOS format.
Firmware disks are shipped with each analyzer. New firmware is released periodically as
improvements are made. You should always keep at least one copy of firmware in a safe
place because you cannot create firmware disks yourself.
If you are upgrading from firmware revision E.05.xx to E.06.xx, you first need to save the
analyzer’s CC data to a floppy disk. It is not necessary to save the CC data if you already
have firmware revision E.06.xx loaded in your analyzer. Upgrading firmware will erase
any data stored in the non-volatile memory such as instrument states and programs. If
these files are needed, copy them to a floppy disk before proceeding.
The following is a generalized procedure for upgrading or re-installing the firmware.
Follow any specific instructions contained in your firmware update kit.
How to Upgrade or Re-Install the Firmware
1. Confirm your current firmware revision by pressing
.
2. If your current firmware revision is E.05.xx, you need to create a "CC DATA" disk. To do
so, follow the procedure in “Storing Correction Constants to Disk” on page 8-3 before
continuing with the next step. If your current firmware revision is E.06.xx, continue
with the next step.
3. Insert firmware disk #1 and cycle the analyzer's line power. The analyzer indicates that
it detects a firmware disk and is about to install the new firmware.
4. Press when prompted. The firmware will begin to load. When prompted, insert
firmware disk #2. Loading of firmware takes about fifteen minutes.
5. When prompted, remove the firmware disk and cycle the power again.
6. If you are upgrading from firmware revision E.05.xx to E.06.xx:
• When the analyzer powers up again, you will briefly see a warning message
indicating that correction constants are not installed, after which you will see the
"Update-Corr-Const" help message. Insert the "CC DATA" disk you created earlier in
this procedure, and press . This loads the CC data from the disk
into the analyzer’s RAM and into the EPROM for permanent storage.
• After the CC data has been installed, cycle the power to the analyzer again. The
firmware upgrade is now complete.
• Store the "CC DATA" disk and the firmware disks in a safe place.
