Install Antivirus Protection

The E4990A does NOT have antivirus protection when shipped. Use of an
antivirus program is strongly recommended if you connect the E4990A to
the LAN (Internet).
In addition, the use of a firewall could help to protect the E4990A from
viruses. However, some firewalls could limit DCOM connectivity of the
E4990A.

Install Windows Critical Updates

The E4990A is always shipped with the latest service packs and critical
updates that were available at the time when firmware is updated. Agilent
recommends you to maintain the latest available protection for your
E4990A by automatically accepting and installing the latest critical security
patches from the Microsoft Windows Update website:
http://windowsupdate.microsoft.com

Precaution for Use of Storage

Do NOT modify or delete any Files and Folders in the drives other than D
drive. Doing so will result in malfunctioning of the device. It is required to
execute the System recovery if there is any trouble with the above
operations.

Precaution for input connector and cable

Do not apply excessive DC voltage or current to the test port.
•
Applying excessive DC voltage or current may lead to device failure.
In particular, the capacitor might remain charged. Connect the
measurement sample (DUT) to the test port (or the test fixture,
cables, etc. connected to the test port) after the analyzer has been
completely discharged. The damage level is described in the
sheet.
Do NOT bend, bump or flex any device under test (DUT) connected
•
to the input of the E4990A (such as filters, couplers etc). This will
reduce the amount of strain placed on the input connector and the
