6AMM7UP Upgrades
3. Discharge the static voltage from your body by wearing a grounded antistatic
wrist strap while handling these modules.
4. Service static-sensitive modules only at a static-free work station.
5. Do not allow anything capable of generating or holding a static charge on the
work surface.
6. Handle circuit boards by the edges or hold onto grounded shields when
possible.
7. Do not slide circuit boards over any surface.
Install the Software Upgrade
CAUTION. To prevent upgrade failure, if your instrument does not have the latest
version of software installed, you must upgrade the software to the latest version
before you install the hardware upgrade and before you install the software
option key.
You do not need to perform the software upgrade if your instrument already has
the latest version of software installed. Perform the following steps to determine
if the software on your instrument needs to be upgraded:
1. Power on the instrument.
2. Verify the installed software version:
a. Press the MAIN button on the front panel.
b. Touch the Config softkey, touch the Utilities soft key, and then touch the
View Hw/Sw Version soft key.

c. On the Software and Firmware Finder Web page, search by model
number (i.e.: AMM768) or use the keyword AMM to locate the
software-upgrade package for your instrument.
d. Note the latest version number of the software-upgrade package(s).
NOTE. If the search for your product produces no results, there are no upgrades
available.
4. If the latest software version at the Web site is newer than the version on
your instrument, you need to upgrade the firmware.
To perform the upgrade, you will use a PC to transfer the new software to the
instrument using your local Ethernet network or using an Ethernet cross-over
cable. Read the entire procedure before starting the software upgrade. The time
required to complete the upgrade is about 25 minutes.
CAUTION. Once the instrument has started to erase internal flash, DO NOT
remove power from the instrument. If you do so, the instrument flash will be
corrupted. The instrument will have to be sent to a Tektronix factory service
center to have the system software restored.
NOTE. If power to the instrument is lost before it begins erasing the internal
flash, you can restart the software upgrade after the instrument reboots.
PC System Requirements. The data-transfer utility used to upgrade the waveform
monitor runs on the following PC systems: Windows 98, Windows NT 4.0,
Windows ME, Windows 2000, and Windows XP. The utility also requires an
Ethernet interface and 128 MB of free disk space on the PC system.
After you have verified that your instrument needs to have the software
upgraded, perform the following procedure:
1. If you are connecting your PC directly to the instrument, connect the
Ethernet cross-over cable between the Ethernet ports on the PC and
instrument, otherwise proceed to step 2.
2. Connect the instrument and PC to your local Ethernet network.
3. Power on the instrument.
Upgrade the Software

4. Assign the instrument an IP address:
NOTE. The data-transfer utility requires that the instrument be assigned a valid
IP address for your network. Network addresses can be assigned either manually
or automatically using DHCP. If your network does not use DHCP, you will have
to manually enter the address for the instrument. To get a valid IP address,
contact your local LAN administrator.
Alternatively, if you connect the PC directly to the instrument using an Ethernet
cross-over cable .You can assign the instrument any IP address that is compat-
ible with the IP address of the PC.

you are using an Ethernet cross-over cable to connect the PC directly to
the instrument. Touch the Close Config Mode soft key to exit the
Config mode.
d. If you selected Manual mode, touch the Network Setup soft key. Enter
the IP address, subnet mask, and gateway address as directed by your
LAN administrator. You need to enter only an IP address if you are using
an Ethernet cross-over cable connection. Touch OK to close the Network
Setup dialog box.
NOTE. If you selected DHCP mode, the network will automatically assign the
instrument an IP address.
5. Download the latest version of software at the Tektronix Web site:
a. Use the Web browser on the PC to navigate to the Tektronix Software
and Firmware Finder Web site:
http://www.tektronix.com/software
