Quick Start Instrument Location and Rack Mounting Requirements

Instrument Location and Rack Mounting Requirements

Locating the analyzer

Make sure that the fan inlet and exhaust vent areas on the sides of the analyzer are not obstructed. The minimal required clearance is 2 inches. Airflow restrictions cause additional airflow noise and cause the fans to speed up so they can draw in enough air for the required cooling. This results in excessive audible noise.

Cooling and rack mounting

Do not rack mount the analyzer side-by-side with any other instrument with side-by-side ventilation. Make sure the exhaust air from the first instrument is directed away from the inlet of the second unit. If the pre-heated air from the first instrument is directed into the second instrument, it can cause excessive operating temperatures in the second unit and can cause instrument failures. The analyzer draws air in from the left side and exhausts air from the right side.
When installing the product in a cabinet, the convection into and out of the product must not be restricted. The ambient temperature (outside the cabinet) must be less than the maximum operating temperature of the product by 4° C for every 100 watts dissipated in the cabinet. If the total power dissipated in the cabinet is greater than 800 watts, then forced convection must be used.

Quick Start Instrument Information

Instrument Information

Power requirements

The only physical installation of your Keysight signal analyzer is a connection to a power source. Line voltage does not need to be selected.
This analyzer does not contain customer serviceable fuses.
The instruments can operate with mains supply voltage fluctuations up to ± 10% of the nominal voltage.
This is a Safety Class 1 Product (provided with a protective earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor inside or outside of the product is likely to make the product dangerous. Intentional interruption is prohibited. (IEC 348 clauses 17.3.3c & 17.3.4)
Failure to ground the analyzer properly can result in personal injury. Before turning on the analyzer, you must connect its protective earth terminals to the protective conductor of the main power cable. Insert the main power cable plug into a socket outlet that has a protective earth contact only. DO NOT defeat the earth-grounding protection by using an extension cable, power cable, or autotransformer without a protective ground conductor.
This product is designed for use in Installation Category II and Pollution Degree 2 per IEC 61010 Second Edition and IEC 664 respectively. This instrument has autoranging line voltage input. Be sure the supply voltage is within the specified range.
The Mains wiring and connectors shall be compatible with the connector used in the premise electrical system. Failure, to ensure adequate earth grounding by not using the correct components may cause product damage, and serious injury.
AC power cord
The analyzer is equipped with a three-wire power cord, in accordance with international safety standards. This cable grounds the analyzer cabinet when connected to an appropriate power line outlet. The cable appropriate to the original shipping location is included with the analyzer.

Keysight NFA X-Series Getting Started and Troubleshooting Guide 17
Quick Start Instrument Information
If this product is not used as specified, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only. Install the instrument so that the detachable power cord is readily identifiable and 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 standby switch and is not a LINE switch. Alternatively, an externally installed switch or circuit breaker (which is readily identifiable and is easily reached by the operator) may be used as a disconnecting device.

Protecting Against Overpowering

The input circuitry of the analyzer can be damaged by applying signals that exceed the maximum safe input level of +30 dBm average total power or +/-
0.2 Vdc (when DC coupled) or +/- 70 Vdc (when AC coupled). Refer to the analyzer's specification guide for more details regarding the Maximum Safe Input Level. Repairing damage to the input circuitry can be expensive.
If the analyzer will be used to measure signals which might be near the maximum safe input level, use external attenuators and/or limiters to help protect the analyzer input. The External Gain, amplitude Corrections, and/or Ref Lvl Offset features may be used to compensate for the gains and losses of external devices. External Gain and Corrections are under the Input/Output menu and Ref Lvl Offset is under the AMPTD Y-Scale menu.

Instrument Maintenance

Cleaning the instrument
To prevent electrical shock, disconnect the signal analyzer from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
18 Keysight NFA X-Series Getting Started and Troubleshooting Guide
Quick Start Instrument Information
Cleaning Connectors
Cleaning connectors with alcohol shall only be done with the instrument power cord removed, and in a well-ventilated area. Allow all residual alcohol moisture to evaporate, and the fumes to dissipate prior to energizing the instrument.
Keep isopropyl alcohol away from heat, sparks, and flame. Store in a tightly closed container. It is extremely flammable. In case of fire, use alcohol foam, dry chemical, or carbon dioxide; water may be ineffective.
Use isopropyl alcohol with adequate ventilation and avoid contact with eyes, skin, and clothing. It causes skin irritation, may cause eye damage, and is harmful if swallowed or inhaled. It may be harmful if absorbed through the skin. Wash thoroughly after handling.
In case of spill, soak up with sand or earth. Flush spill area with water.
Dispose of isopropyl alcohol in accordance with all applicable federal, state, and local environmental regulations.

The analyzer uses a lithium battery located on the CPU board. This is not an operator replaceable part. See “Returning an Analyzer for Service” on
page 93. Replaceable parts must be approved or supplied by Keysight
Technologies.
You can order the service documentation for the instrument through your Keysight Sales and Service office.
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended. Discard used batteries according to the manufacturer’s instructions.
Do not throw batteries away but collect as small chemical waste.
Keysight NFA X-Series Getting Started and Troubleshooting Guide 19
Quick Start Instrument Information

Protecting against electrostatic discharge

Electrostatic discharge (ESD) can damage or destroy electronic components (the possibility of unseen damage caused by ESD is present whenever components are transported, stored, or used).
Test equipment and ESD
To help reduce ESD damage that can occur while using test equipment:
Do not use these first three techniques when working on circuitry with a voltage potential greater than 500 volts.
— Before connecting any coaxial cable to an analyzer connector for the first
time each day, momentarily short the center and outer conductors of the cable together.
— Personnel should be grounded with a 1 MΩ resistor-isolated wrist-strap
before touching the center pin of any connector and before removing any assembly from the analyzer.
— Be sure that all instruments are properly earth-grounded to prevent
build-up of static charge.
— Perform work on all components or assemblies at a static-safe workstation.
— Keep static-generating materials at least one meter away from all
components.
— Store or transport components in static-shielding containers.
— Always handle printed circuit board assemblies by the edges. This reduces
the possibility of ESD damage to components and prevent contamination of exposed plating.
Additional information about ESD
For more information about ESD and how to prevent ESD damage, contact the Electrostatic Discharge Association (http://www.esda.org). The ESD standards developed by this agency are sanctioned by the American National Standards Institute (ANSI).

Quick Start Using the U7227-Series USB Preamplifiers in Noise Figure Measurements

Using the U7227-Series USB Preamplifiers in Noise Figure Measurements

The U7227-Series USB Preamplifiers turn the overall X-Series noise figure analyzers into better noise figure analyzers by reducing instrument noise figure. Reducing instrument noise figure is necessary when the device under test (DUT) is lossy or has low gain. This is because the instrument noise figure contributes more to the final measurement uncertainty when the gain of the DUT is low. Figure 1-1 shows how the measurement uncertainty of a typical noise figure measurement depends on the DUT gain and instrument noise figure. The data is derived using the Uncertainty Calculator in the N9069C noise figure measurement application. It can be seen that the measurement uncertainty increases when the DUT gain is low and instrument noise figure is high. In optimal noise figure measurements, these regions should be avoided. Therefore adding preamplifier correction data is not necessary.
Figure 1-1 3-D Plot of Measurement Uncertainty versus DUT Gain and Instrument Noise

This section first introduces how to connect the U7227-Series USB Preamplifier to the signal analyzer and then provides a rough guide about using the USB preamplifier and the internal preamplifier inside the signal analyzer.

Quick Start Using the U7227-Series USB Preamplifiers in Noise Figure Measurements

Initial Connection to the Signal Analyzer

The U7227-Series USB Preamplifier is powered via a USB connection from the signal analyzer. To connect it to the analyzer, follow the steps below.
Before connecting a signal to the input port of the U7227-Series USB Preamplifier, make sure the USB preamplifier can safely accept the signal level provided. The signal level limits are marked next to the Input connectors of the USB preamplifier.
1. Connect the Output port of the USB preamplifier to the RF Input port of the signal analyzer.
2. Connect the USB port (Type-B) of the USB preamplifier to the USB port (Type-A) of the signal analyzer either in the front panel or in the rear panel using a USB cable. You can “hot plug” the USB preamplifier into the analyzer’s USB port at any time.
The USB connections of the U7227-Series USB Preamplifier and the keyboard to the signal analyzer must be separated from each other; for example, the USB preamplifier connects through the front panel while the keyboard connects through the back panel.
Figure 1-2 shows the U7227-Series USB Preamplifier connection in the two
stages of the noise figure measurement. While the USB preamplifier is plugged into one of the analyzer’s USB ports, the analyzer will consider it to be in the RF input signal path and will apply the gain settings and other calibration data of the USB preamplifier to the measurements.

In the noise figure measurement application, the signal analyzer will respond in the following manner when the USB cable of the U7227-Series USB Preamplifier is plugged into one of the analyzer’s ports:
1. The sweep will pause momentarily while the “Hardware Configuration Updating” message appears on the signal analyzer display. See Figure
1-3.
Figure 1-3 “Hardware Configuration Updating” Message
2. The USB preamplifier’s calibration data, such as gain, noise figure, and
S-parameters, will be automatically downloaded into the analyzer.
The USB preamplifier’s RF output cable, connector loss, and frequency response are accounted for in the data that is automatically downloaded into the analyzer’s memory. The calibration data is not user accessible.
3. The “Ready” LED is lit on the USB preamplifier.
4. The USB preamplifier’s model and serial number will be displayed. See
Figure 1-4.

Guide for Using U7227-Series USB Preamplifier and the Internal Preamplifier inside X-Series Signal Analyzer

This section provides a rough guide for using the U7227-Series USB Preamplifier, the internal preamplifier, and the internal attenuator together to make accurate noise figure measurements.
Amplitude Concerns in the Noise Figure Test System
Before talking about the guide, let us look at some signal amplitude concerns in the test system. Figure 1-5 shows all the possible blocks in the signal path of the noise signal in the noise figure measurement. The blocks with dotted lines indicate that you can choose whether to use them or not. The USB preamplifier, the internal preamplifier and input mixer inside the signal analyzer are non-linear components and have a limit on the largest signal that can be processed. The power limits of the noise signal are for the following places:
— before the USB preamplifier
— before the internal preamplifier
— before the input mixer
To make an accurate noise figure measurement, the noise power should be below the maximum allowable power at all these three places. You can refer to the technical overview of the U7227-Series USB Preamplifier and the specification guide of the X-Series signal analyzer to check the maximum allowable powers. For power levels before the internal preamplifier and before the input mixer, the internal attenuator inside the signal analyzer can be applied to reduce the power level. But at the same time, the instrument noise figure will increase with using the internal attenuator.
The rough guide for the noise figure test system configuration in the following section is based on the noise power calculation before the non-linear components.

Using the U7227-Series USB Preamplifiers in Noise Figure Measurements
Rough Guide for the Noise Figure Test System Configuration
To configure the test system for accurate noise figure measurements, the first priority is to make the instrument noise figure (USB preamplifier + signal analyzer) as low as possible. To reduce the instrument noise figure, the USB preamplifier and internal preamplifier should be used whenever possible. If an overload or compression exists in the test system, removing or turning off the preamplifier (USB preamplifier or internal preamplifier) or adding internal attenuation can eliminate the problem. On the signal analyzer,
— To turn on/off the internal preamplifier, press AMPTD, Signal Path tab,
Internal Preamp, On/Off.
— To set the internal attenuator, press AMPTD, Attenuation tab, and set the
attenuation.
Figure 1-6 and Figure 1-7 show the supported DUT characteristics (noise
figure and gain) of different system configurations for different frequency ranges up to 26.5 GHz. The X-axis is for the DUT noise figure, the Y-axis is for DUT gain, and the different colors on the figures indicate the recommended test system configurations. This rough guide is based on the noise power calculation before the non-linear components.
Before using Figure 1-6 and Figure 1-7 to find a proper test system configuration, you need to pay attenuation to the following points:
— The DUT reference bandwidth used to calculate the noise power is 3.59
GHz, which is the worst case for the lower band (10 MHz to 3.6 GHz). To maintain consistency between the lower band and higher band, the same DUT reference bandwidth is used in the calculation for frequency ranges above 3.6 GHz. Then the reference bandwidths (Ref_BW) for both below 3.6 GHz and above 3.6 GHz are both 3.59 GHz.
If the DUT has a narrower bandwidth, the DUT characteristics can be increased accordingly. For example, if the DUT has a bandwidth of 100 MHz, the supported DUT gain can be increased by a factor of
, that is by 15.6 dB.
— The noise figure and gain for the U7227C USB Preamplifier are used in the
calculation. If you are using the U7227A or U7227F, the supported DUT characteristics should be different.
— A 6 dB ENR noise source is used in the calculation. If you are using a noise
source with higher ENR, the supported DUT gain will be lower.
— For different instruments and for a wide frequency range, the data for the
USB preamplifier and the X-Series signal analyzer differs considerably, the most precise data is used in most cases.

Using the U7227-Series USB Preamplifiers in Noise Figure Measurements
Below is the procedure for using Figure 1-6 and Figure 1-7 to find the proper system configuration. See “Examples for Using the Guide to Find the Test
System Configuration” on page 30 for examples of using this procedure.
1. Check the DUT and get the rough data for the DUT bandwidth (BW), noise figure (NF), and gain.
2. Calculate the bandwidth adjust factor (AF) using the following equation.
1
Then subtract the AF from the DUT_Gain. The resul tant value is called DUT_Gain_Modified.
3. Use the DUT_NF and DUT_Gain_Modified values to search in Figure 1-6 or
Figure 1-7 from bottom to top and find an approximate place for them.
4. Find the corresponding system configuration. If the system configuration includes the internal attenuation, do the following to find the proper attenuation level:
a. Set the attenuation to 0 dB and note the noise figure of your DUT.
b. Increase the attenuation by one step (4 dB). If the noise figure
changes too much, such as 0.3 dB, this attenuation is required for accurate measurement.
c. Repeat step (b) until you find the proper value.
As in the calculation of the supported DUT characteristics in Figure 1-6 and Figure 1-7, the most precise data is used in most cases, it is recommended to try the system configuration below the one you find using DUT_NF and DUT_Gain_Modified first.

For frequency ranges above 3.6 GHz, if no preamplifier is used in the signal analyzer, the major noise power concern will be the noise power before the mixer. In this case, the input noise outside the preselector bandwidth (less than 80 MHz) will be filtered. This may affect the supported DUT characteristics.
Figure 1-6 and Figure 1-7 provide a rough guide for frequency ranges up to
26.5 GHz. For the frequency ranges above, the U7227F USB Preamplifier used together with the X-Series can support up to 50 GHz. The calculation method for frequency ranges above 26.5 GHz is similar to the “3.6 GHz to 26.5 GHz” frequency range. The supported DUT gain will decrease because of the increase of the noise figure and gain for both the USB preamplifier and the internal preamplifier. Refer to Table 1-1 and Table 1-2.

Front and Rear Panel Features Display Features

Display Features

This section describes the regions of the display.

Invalid Data Indicator

The invalid data indicator is displayed whenever the data on the display
does not match the settings of the analyzer. The most common example of this is when instrument settings have changed in the time since the data in the traces on the display was taken. This means that the screen annotation cannot be guaranteed to match the trace data. For example, if you change Center Frequency, the invalid data indicator will display until a new sweep has completed.
If any Trace is in View mode (displaying but not updating) and analyzer settings are changed, the invalid data indicator will display as long as that trace remains in View. Traces that are blanked do not turn on the invalid data indicator.
Not all analyzer settings require display of the invalid data indicator when they change, only changes that require a new acquisition will cause it to display. For example, changing the Y-Axis scale of the analyzer does not cause the invalid data indicator to display, unless the attenuation changes.
Also, the invalid data indicator is turned on:
— When the counter is turned on, until the completion of the first count
Keysight NFA X-Series Getting Started and Troubleshooting Guide 37
Front and Rear Panel Features Display Features
— When a trace is imported from mass storage and the trace’s parameters do
not match the current analyzer settings
— When a trace is sent to the analyzer from a remote interface (since there is
no way to know if its settings match)
The Data Invalid Indicator has an associated status bit that can be checked at any time to see if it is on.

Screen Tabs

Along the top of the display are tabs, one for each measurement screen you have defined. Tap the + sign to "clone" the current measurement, which can be changed once it is created. Tap the current screen tab (or press the Mode/Meas hardkey) to display the following dialog:
This dialog allows you to choose a Mode, Measurement and View.
When you select a mode, the measurements that are available in the mode are displayed in the Measurement column.

Instrument Operating System Microsoft Windows

Microsoft Windows

Your instrument has Microsoft Windows installed at the factory. Keysight has already configured many of the settings in Microsoft Windows for optimal behavior in your instrument. This chapter contains details about many of these settings.

Keysight Software Installed

Keysight Noise Figure Analyzer software

The N9069C Keysight Noise Figure Measurement Application software is installed in the analyzer. The instrument comes preconfigured with full featured Spectrum Analyzer and IQ Analyzer (Basic) modes preinstalled.
If you install programs other than those that Keysight has tested, it could cause problems with the instrument's applications. If this happens, you should try uninstalling the program that has caused the problem, or try changing the program's configuration. If this does not correct the problem, you may have to use the Keysight Recovery system to reinstall the instrument's system software
48 Keysight NFA X-Series Getting Started and Troubleshooting Guide

User Accounts

Administrator account

Instrument Operating System User Accounts
The instrument ships with a number of different accounts already set up. In addition you can create your own accounts if you desire. The privileges associated with each account determine what you can and cannot do from that account.
Using the Administrator account you can perform the following operations:
—Install software — Configure network and printer access — Access all files on the instrument — Add or change user accounts and passwords — Change Firewall settings — Change Windows settings (e.g., using Device Manager) — Change the time and date — Run any application
The default password is "Keysight4u!".

Instrument accounts

The default user account that ships from the factory is “Instrument” with the password “measure4u”. This user is a member of the standard Users group. Using the Instrument account, you may perform the following operations:
— Configure network and printer access (although not local printer access) — Access files on the instrument that are accessible to the Users group — Run applications that are accessible to the Users group

KeysightOnly user account

The instrument contains a user account called "KeysightOnly" that can be used by Customer Support in the event that the customer has changed the Administrator password and has forgotten the password. You must not remove or modify the KeysightOnly account.

Service user accounts

There are user accounts defined in the instrument for servicing the instrument.

Customer creation of accounts

You can create additional user accounts and decide on the level of security granted to any new user accounts created. For example, the level of security can be assigned as administrator, power user, standard user, backup operators. User names are not case sensitive but passwords are case sensitive.
Keysight NFA X-Series Getting Started and Troubleshooting Guide 49
Instrument Operating System User Accounts
It is Keysight’s expectation that each user’s My Documents folder is mapped to the D: drive. This is to avoid overwriting the user’s data in the event the Instrument Recovery must be performed. Also, this facilitates convenient backup by copying the contents of the D: drive to external media. All user accounts created by the factory already have My Documents mapped to the D: drive. It is recommended to map all new users’ My Documents folders to the D: drive.

Keysight NFA X-Series Noise Figure Analyzer Options

The following measurement applications are preinstalled and licensed in the noise figure analyzer:
1. Noise Figure
2. Spectrum Analyzer
3. IQ Analyzer (Basic)
The licenses for these measurement applications are fixed perpetual.

Fixed Perpetual

Fixed Perpetual licenses are the traditional license type (Fixed) with the same duration (Perpetual) that have been available for all features since the introduction of the X-Series analyzers. Fixed Perpetual licenses are identified by the “F” in the second character and “P” in the third character of the option designator:
Example: N9069EM0E-1FP
A license key is instrument model and serial number dependent. You can only install the license key on the specific instrument for which it was created.

Instrument Operating System Windows Security

Windows Security

Microsoft recommends the following to ensure the instrument's Windows operating system is protected:
—Use an internet firewall.
— Get the latest critical Windows updates.
— Use up-to-date antivirus software.

Windows Firewall

The instrument is shipped with the Windows Firewall enabled. You can verify the status of Windows Firewall by going to the Control Panel and clicking on System and Security, Windows Firewall.
Windows Firewall Exceptions for programs and ports have been added to allow proper operation of the instrument over a network. Modifying these settings may cause the instrument to not operate properly.

Instrument Operating System System Maintenance

System Maintenance

Backup

It is recommended that you have a regular backup strategy. Your IT department may already have a backup strategy in place which is suitable for the instrument and its data. Using the Instrument Recovery system in conjunction with a regular backup strategy should allow full recovery of the instrument data.
Windows has a Backup utility that you can use to archive files and folders in case of a disk drive failure. See the Windows Help and Support Center for more information on this utility. You can also use third party backup utilities. However, you must ensure that this third party software is compatible with the instrument's system software.
When performing backups, we recommend that you backup the data to an external storage device connected to the network or one of the instrument's USB connectors. Also, you should perform backups at times when the instrument is not being used for normal operations, as it may impact the instrument's overall performance.

System Restore

Windows contains the capability to restore the system to a previous point in time. System Restore is enabled with default settings as provided by Microsoft. However, System Restore is not always 100% successful. Therefore, it is not recommended that you rely on System Restore to protect your instrument. System Restore has not been tested to verify successful restoring.

Disk Defragmenting

The instrument has a solid state drive. Disk defragmenting is not recommended.

Instrument Operating System USB Connections

USB Connections

All of the USB ports are compatible with the USB 2.0/3.0 and 1.1 specification. The three USB ports on the front panel (see graphic below) and three of the USB ports on the rear panel are USB Series “A” ports. These are ports to which you can connect USB mass storage devices and printers. The instrument USB Host support includes the standard Microsoft Windows USB drivers for human interface, mass storage, printing, scanning, and imaging devices. A complete up-to-date list of the Windows USB class driver support is available on the Microsoft website.
The square USB port (see graphic below) on the rear panel is a USB 3.0 Series “B” port and is used for controlling the instrument over USB. Information to help you program your instrument is documented in the X-Series Programmer’s Guide. The instrument USB device driver included in the instrument software supports the test and measurement industry standard USBTMC-USB488 device class.
In addition, the IO Libraries CD that was included with your instrument contains USB Host drivers that allow control of other instruments connected to the USB ports.
Keysight Technologies does not support or warrant correct instrument operation if additional USB drivers from third parties are installed in the instrument. It is possible that additional drivers could break the normal USB operation. If USB operation is broken, recovery would require reinstalling the instrument application using the Instrument recovery process.

Instrument Operating System Disk Drive Partitioning and Use

Disk Drive Partitioning and Use

The drive is partitioned into 3 sections: C:, D: and E:
—The C: partition contains the Windows 10 operating system and software
installed by Keysight. This is an Open System which means you can install additional software, and these should be installed on the C: drive. However, only a limited set of software applications are tested for use with the Keysight measurement software. The installation and/or use of other software is not warranted and could interfere with the operation of the measurement software. If instrument repair is ever needed, the Keysight version of the C: drive is the only part of the instrument software that is restored by the Instrument Recovery process. You must reload any other software that you have added in the instrument.
—The D: partition is reserved for data storage. The User Accounts that are
configured by Keysight have their My Documents folder mapped to the D: drive. This is for the convenience of backing-up the measurement data. You should always back-up the data on the D: drive to an external device. This allows you to restore the data if you ever need to replace the disk drive.
Table 3-3
—The E: partition is reserved for Keysight’s use. The primary use of the E:
drive is for housing the Calibration and Alignment data. Do not change or overwrite the files on this drive. This could cause your instrument to not meet specifications, or even to stop functioning correctly. Do not use this drive for data storage. It is also recommended that you back up the contents of this drive by using the factory calibration data backup utility.

Backing-up the factory calibration data

To back-up the factory calibration data you will need a USB storage device.

Instrument Operating System Disk Drive Recovery Process

Disk Drive Recovery Process

The Instrument Recovery System can be used to repair errors on the instrument's C: drive partition or to restore the original factory configuration of the system software on the disk drive. The Instrument Recovery System is stored in a separate hidden disk drive partition.
Repairing errors on the disk drive may result in loss of data or files. If you require more information, see the “chkdsk” documentation in the Windows Help and Support Center.
Restoring the original factory system software does not restore any of the following items:
— Additional software that has been installed after the instrument was
shipped from the factory. (Thus, following an Instrument Recovery any software installed after the instrument was shipped from the factory will need to be re-installed.)
— System configurations (for example user accounts, windows configurations)
that have been made after the instrument was shipped from the factory. (Thus, following an Instrument Recovery configuration changes will have to be performed.)
— The Instrument Recovery overwrites the contents of the C: partition. It does
not affect the D: or E: partitions.
It is recommended that the customer use a regular back up strategy. The customer’s IT department may already have a backup strategy in place which is suitable for the instrument and its data. Using the Instrument Recovery System in conjunction with a regular back up strategy should allow the customer to fully recover the instrument's software and data.

Remote Desktop: Using the X-Series Instruments Remotely

Windows Remote Desktop is recommended for remote control of the instrument. It offers fully-interactive control that is almost identical to direct face-to-face control of the instrument. You can also remotely control the instrument using the Embedded Web Server interface. The Embedded Web Server functionality provides a communications method that does not require login to the instrument. However, due to its slower response time, it is only recommended for setup and data exchanges that do not involve instrument control.
The Remote Desktop functionality is a Microsoft Windows 10 capability. The following discussion provides some guidelines for using this capability with the instrument. You need to refer to the Windows 10 help documentation for more information. As Windows evolves, these instructions may no longer be exact.
You need an external keyboard and mouse to fully use this functionality.

Overview of Remote Desktop operation

Using the Remote Desktop functionality of the instrument allows you to control and interact with the instrument from a remote computer as though you were sitting in front of the instrument.
When you have configured the instrument for remote connectivity, and configured a separate computer to act as a Remote Desktop Host, you can send commands to the instrument from the remote computer, and you can see the instrument display on the screen of the remote computer.
This section provides full details of how to set up the instrument for remote connectivity, and also how to set up a computer running any version of Microsoft Windows as a Remote Desktop Host.

Troubleshooting Returning an Analyzer for Service

Read the Warranty

The warranty for your analyzer is in the front of your Specifications Guide. Please read it and become familiar with its terms.
If your analyzer is covered by a separate maintenance agreement, please be familiar with its terms.

Service Options

Keysight Technologies offers several optional maintenance plans to service your analyzer after the warranty has expired. Call your Keysight Technologies office for full details.
If you want to service the analyzer yourself after the warranty expires, you can download the service documentation that provides all necessary troubleshooting and maintenance information from the Keysight web page.
Performance Verification and Adjustment tests require the N7881A X-Series Signal Analyzer Calibration Application Software. Information regarding the N7881A X-Series Signal Analyzer Calibration Application Software can be found at:

Troubleshooting Returning an Analyzer for Service

Packaging the Instrument

Use original packaging or comparable. It is best to pack the unit in the original factory packaging materials if they are available.
Analyzer damage can result from using packaging materials other than those specified. Never use styrene pellets in any shape as packaging materials. They do not adequately cushion the equipment or prevent it from shifting in the carton. They cause equipment damage by generating static electricity and by lodging in the analyzer louvers, blocking airflow.
You can repackage the analyzer with commercially available materials, as follows:
Table 5-1
Step Notes
1. Wrap the analyzer in anti-static plastic to reduce the possibility of damage caused by electrostatic discharge
2. Use a strong shipping container. The carton must be both large enough and strong
enough to accommodate the analyzer. A double-walled, corrugated cardboard carton with 159 kg (350 lb) bursting strength is adequate. Allow at least 3 to 4 inches on all sides of the analyzer for packing material.
3. Surround the equipment with three to four inches of packing material and prevent the equipment from moving in the carton.
4. Seal the shipping container securely with strong nylon adhesive tape.
5. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to assure careful handling.
6. Retain copies of all shipping papers.
If packing foam is not available, the best alternative is plastic bubble-pak. This material looks like a plastic sheet filled with 1-1/4 inch air bubbles. Use the pink-colored bubble which reduces static electricity. Wrapping the equipment several times in this material should both protect the equipment and prevent it from moving in the carton.
