To protect your ENA, follow the instructions below:
Do not exceed the values provided in the specifications guide or as indicated by the yellow warning labels on the front panel of ENA. Refer to the specifications for the conditions required to meet the listed specifications. There will be information regarding ENA settings, and calibration requirements.
Do Not Plug off Power cable until completely completing the shutdown process.
If you directly interrupt the power supply to the power cable receptacle when the power supply is on, or turn off the Line Switch (Always ON), the shutdown process will not work. This could damage the HDD of the E5071C.
The Microsoft Windows operating system has been modified and optimized by Keysight to improve the performance of the ENA.
Do NOT install a standard version of the Windows operating system on the ENA.
Do NOT change advanced performance settings or group policies.
Do NOT add or delete any hard disk drive partitions on the ENA.
Do NOT delete the Keysight user account.
Do NOT modify any of the Keysight software registry entries.
DO NOT change the setting of BIOS
Do NOT change the settings of Standards and Formats in Regional Options and Languages from default setting (English).
The ENA does NOT have antivirus protection when shipped. Use of an antivirus program is strongly recommended if you connect the ENA to the LAN (Internet).
In addition, the use of a firewall could help to protect the ENA from viruses. However, some firewalls could limit DCOM connectivity of the ENA.
The ENA is always shipped with the latest service packs and critical updates that were available at the time when Firmware is updated. We recommend that you maintain the latest available protection for your ENA by automatically accepting and installing the latest critical security patches from the Microsoft Windows Update website: http://windowsupdate.microsoft.com.
The measurement speed may become slower while windows update is running.
When the ENA is shutdown unexpectedly or power is removed without first shutting down, large amounts of Hard Disk Drive space is rendered unusable. If shutdown in this manner enough times, the ENA could become unstable and no longer work.
This HDD space can be recovered by first running Windows Error-checking to find and correct errors on the disk, and then the Disk Defragmenter to recover Hard Disk Drive space. See the Windows Help file for more information about Disk Defragmenter.
To run error check and defragmenter follow the procedure below:
On the desktop, double-click My Computer.
Select System OS.
Click File, then Properties.
Click the Tools tab.
Click Check Now.
Check Automatically fix file system errors.
Click Start.
Click Yes to run disk check on next restart.
Manually restart the ENA. The disk check will run before Windows restarts.
Periodically, check the second box in addition to the first box. The error-checking process takes much longer, but performs a complete check.
Click Defragment Now...
Click Defragment to begin the defragment process.
Click Close when defragmentation is complete.
Do NOT Modify or delete any Files and Folders in Drive other than D and E: Drive.(These two drives, D and E are available to use as Data backup). Doing so will result in malfunctioning of the device. It is required to execute the System recovery if there are any troubles with the above operations.
For Option 017 users:
Do not remove removable hard disk until completely completing the shutdown process.
Do not unlock the removable hard disk key until completely completing the shutdown process.
Do not apply DC voltage or current to the test port. Applying 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 maximum DC limit of test port is 35V.
Do NOT bend, bump or flex any device under test (DUT) connected to the input of ENA (such as filters, couplers etc). This will reduce the amount of strain placed on the input connector and the mounting hardware. Make sure externally connected items are properly supported (not freely suspended) from the input.
Do NOT bend cables repeatedly, as this may damage the cable instantly. Limit the number of connections and disconnections to reduce wear. Inspect connectors prior to using; look for dirt, nicks, and other signs of damage or wear. A bad connector can ruin a good connector instantly. Clean dirty connectors to prevent poor electrical connections and damage to the connector. For more information on cable and connector care, refer to www.keysight.com/find/cable_care
ESD can damage or destroy electronic components. Whenever possible, conduct testing at a static-safe workstation. Keep static-generating materials at least one meter away from all components. Before connecting any coaxial cable to an analyzer, momentarily short the center and outer conductors of the cable together.
Control your environment. Maintain temperature & humidity with a satisfactory range within the instruments specification and prevent large fluctuations.
Do NOT pick the instrument with your hand over the front panel. If the instrument slips, damage may occur to the keypad, knob, or input connectors. Lift the Instrument by the handles when transporting.
Do NOT use styrene pellets as packaging materials as these may cause damage to ENA by generating static electricity.
Periodically check and clean the cooling vents of the ENA. Inadequate airflow can result in excessive operating temperatures which can lead to instrument failures. When installing the product in a cabinet, the convection into and out of the instrument must not be restricted.
See the installation guide in detail.
Proper grounding prevents building-up of static charge which may be harmful to ENA.
Do NOT defeat the earth-grounding protection by using an extension cable, power cable, or autotransformer without a protective ground conductor.
