Operating Precautions

Most causes of instrument failure can be avoided if you will apply the information in this section. PLEASE READ!

Preventing Electrostatic Discharge Damage

Protection against electrostatic discharge (ESD) is essential while removing assemblies from or connecting cables and assemblies (DUT) to the network analyzer. Static electricity can build up on your body and can easily damage sensitive internal circuit elements when discharged. Static discharges too small to be felt can cause permanent damage. To prevent damage to the instrument:

• always have a grounded, conductive table mat in front of your test equipment.
• always wear a grounded wrist strap, connected to a grounded conductive table mat, having a 1 MΩ resistor in series with it, when handling components and assemblies or when making connections.
• always wear a heel strap when working in an area with a conductive floor. If you are uncertain about the conductivity of your floor, wear a heel strap.
• always ground yourself before you clean, inspect, or make a connection to a static-sensitive device or test port. You can, for example, grasp the grounded outer shell of the test port or cable connector briefly.
• always ground the center conductor of a test cable and DUT before making a connection to the analyzer test port or other static-sensitive device. This can be done as follows:
  1. Connect a short (from your calibration kit) to one end of the cable and DUT to short the center conductor to the outer conductor.
  2. While wearing a grounded wrist strap, grasp the outer shell of the cable and DUT connector.
  3. Connect the other end of the cable to the test port.
  4. Remove the short from the cable.

The following table lists Keysight part numbers for ESD protection devices. To order, refer to "Contacting Keysight".

Preventing Electrical Overstress Damage

NOTE
The instrument can operate with mains supply voltage fluctuations up to ± 10% of the nominal voltage.
Excessive RF power or voltage applied to the ports and connectors on the front panel will damage the analyzer. Each port and front-panel connector has a label (see photo below) that shows damage levels. These levels must not be exceeded. Damage levels are also listed in the Specifications section of the analyzer's Help system.

There are two ways to protect the PNA input ports from high RF power:

1. Use power limiters at the ports. Information on limiters can be found at: www.keysight.com/find/mta.
2. Apply the recommendations in PNA Application Note 1408-10, "Recommendations for Testing High-Power Amplifiers," found at: https://www.keysight.com/us/en/assets/9921-01766/user-manuals/Users-Guide-A-Series-N991xA-2xA-3xA-5xA-6xA-Unabridged.pdf (5989-1349EN).

Preventing Test Port Connector Damage

Proper connector care and connection techniques are critical for accurate and repeatable measurements. The following table contains for tips on connector care.
For more information on the proper use and maintenance of connectors, see https://rfmw.em.keysight.com/wireless/helpfiles/N52xxB/Tutorials/Connector_Care.htm.

   • The instruments can operate with mains supply voltage fluctuations up to ± 10% of the nominal voltage.
     1. Ensure the available AC power source meets the following requirements:

        Model	Mains Supply Voltage	Frequency	Power
        N52xxB models:	100-120 VAC	50/60/400 Hz	575W MAX
        	200-240 VAC	50 /60 Hz	575W MAX
        NA520xA models:	100-120 VAC	50/60/400 Hz	1200Wa
        	200-240 VAC	50 /60 Hz	1200Wa

        1. The power rating for these models requires that the instrument be plugged into a dedicated circuit.
     2. Verify that the AC power cable is not damaged, and that the power-source outlet provides a protective earth contact.
        
        Use Keysight supplied power cord or one with same or better electrical rating.
        
        Always use the three-prong AC power cord supplied with this product. Failure to ensure adequate earth grounding by not using this cord may cause personal injury or product damage.
        
     3. Ensure the operating environment meets the requirements found in "Safety, Regulatory, and Environmental Information".
        NOTE
        Some analyzer performance parameters are specified for 25°C. Refer to the Help system in the analyzer for the complete specifications.
3. Install the Analyzer
   
   Please review all safety information located in "Safety, Regulatory, and Environmental Information", before proceeding with installing and using the analyzer
   The analyzer can be installed on a bench top or in an equipment rack. When installing an analyzer equipped with handles in an equipment rack, use Option 1CP. When installing an analyzer not equipped with handles in an equipment rack, use Option 1CM.
   In all installations, consider the following ventilation requirements when deciding where to set up your analyzer.
   To Install in an Equipment Rack
   (Option 1CP - Rack Mounting For Instruments Equipped With Handles)
   (Option 1CM - Rack Mounting For Instruments Not Equipped With Handles)
   When you install the analyzer in an equipment rack, you must install rails in the rack to support the weight of the analyzer. Attach either the Option 1CP or Option 1CM rack mount flanges to the analyzer. Secure the analyzer to the equipment rack. Replace the analyzer bottom plastic feet with the hole plugs provided.
   For installation, follow the instructions provided with the rack mount kit and the rail kit.
4. Connect the Accessories
   USB devices can be connected to any available USB port. All ports comply with a minimum of USB 2.0 specifications. The PNA will recognize the USB device when it is connected and run the appropriate software driver to make the device operate correctly. However, there is a limit to the amount of current that the PNA USB ports can provide. See PNA Help - "USB port specifications" (index entry) for more information.
   When starting the PNA, do not have any USB devices connected other than a mouse and keyboard. The current draw from other accessories can impact the initial boot-up sequence.
   NOTE
   Consider ergonomics when locating the mouse and keyboard.
   NOTE
   Do NOT connect an ECal module to the USB until after the PNA is started. Once the PNA is started, press the front panel Help button to learn about 'Connecting an ECal module for the first time'.
5. Ferrite Cores
   CISPR 11 is an international regulation that specifies the maximum level of frequency emissions that can originate from an electronic device. The regulation is designed to minimize the interference that one electronic device may have with another.
   Frequency emissions can occur when cables are connected to an electronic device. To minimize this, try to use high-quality cables with built-in molded ferrite cores, with the core closest to the PNA. If cables with built-in cores cannot be found, use clamp-on ferrite cores. It is especially important to use these cores on USB cables and LAN cables.
   The core should snap closed to grip the cable firmly, but without damaging the cable. Attach the core to the cable as close as possible to the PNA connector end. Cable ties help ensure that the ferrite cores remain in place
   
6. Start Up the Analyzer
   
   Install the instrument so that the detachable power cord is readily identifiable and is easily reached by the operator. The detachable power cord is the instrument disconnecting device. It disconnects the mains circuits from the mains supply before other parts of the instrument. The front panel switch is only a ON/Standby switch and is not a LINE (OFF) switch.
   1. Connect the AC power cable.
   2. Turn the analyzer on by pressing the front panel On/Standby switch.

Do NOT press keys on the front panel, rotate the RPG knob, or connect a USB device during boot up of Windows or of the PNA application program. Doing so may lead to a front panel lockup state.

NOTE
This product contains a Windows operating system. The Network Analyzer application is supported and qualified only with the version of Windows that was installed when shipped.

Windows 10 Operating Systems
Windows 10 comes with a display technology called ClearType. This makes displayed text much easier to read on the PNA. The only drawback comes with viewing the display from the bottom. The colors of some small display elements will appear to shift when the viewer's eyes are more than 30 degrees below perpendicular. If necessary, ClearType can be disabled. On the PNA desktop, click Start, then Control Panel then Appearance and Personalization, then Display, then Adjust ClearType Text.

7. Perform Administrative Tasks
   We recommend that you consider performing the following administrative tasks shortly after powering up the analyzer for the first time.
