9 Security Issues for Certain
Firmware Revisions
The information in this chapter applies only to PSG and ESG Signal Generators.
If your ESG or PSG instrument currently has one of the firmware revisions listed in Table 9-1 , using certain
security features may cause the deletion of some of the instrument’s system files. Before using the security
features, update your firmware to the appropriate revision listed in the "Update to" column of Table 9-1 .
Firmware Update Procedure
To obtain the latest firmware online, perform the following steps:
1. Access the instrument’s web page:
www.agilent.com/find/<model_number>
(Example:
www.agilent.com/find/E4438C).
2. Under the Technical Support Tab , select Drivers and Software , and follow the remaining links to the
firmware upgrade page.
If web access is not available, Agilent can provide the new firmware on CD-ROM. To obtain the CD-ROM,
contact Agilent or your Agilent representative, as described in “Contacting Agilent Sales and Service Offices”
