Initial Setup
Introduction
Introduction
Use this guide to unpackage and set up your benchtop N5511A Phase noise
test system.
Check all the cable connections to the Phase detector, Data Converter and
Reference modules.
Power on the N5511A unit for the first time. The N5511A system will arrive with
the instrument software and licenses already installed. Before making your first
measurement, you should check the installed assets and add any additional
assets to the system.
After adding the reference sources (spectrum analyzer and oscilloscope (not
required)) to the system, perform the first measurement. Perform the system
functional check by making an Absolute Phase Noise Measurement as your
first measurement.
Use Table 1-1 as a guide to the chapters to use for your benchtop system:
If you need to upgrade the phase noise software in the N5511A system controller for any reason,
refer to the N5511A Phase Noise Test System User’s Guide for information and procedures.

Unpacking and Inspecting the System
Unpacking and Inspecting the System
This section presents procedures for unpacking a benchtop model. Do not
attempt to unpack your system without reviewing them.
To unpack a benchtop system
To unpack an N5511A benchtop system, you need the following tools:
— Safety glasses
—Utilityknife
1. Cut open the shipping container.
2. Remove and open the accessory shipping box.
3. Remove the box contents list.
4. Retain all calibration and shipping documents.
Retain all packing material—front panel instrument cover, boxes, and foam—for future use should
you need to move the system to another location or return for service.

Initial Setup
Unpacking and Inspecting the System
Verify shipping contents
After unpacking the shipping container, the next step is to inspect the contents
thoroughly to ensure that nothing was damaged during shipment.
Verify that all parts and materials are included in your shipment:
— N5511A Phase Noise Test System - Getting Started Guide
—CertificateofCalibration
—Powercord
The N5511A system is shipped with an AC power cord appropriate for your
location.
— Instrument connectors and adapters specific to your system
— Keyboard and mouse
— Torque wrench, 8 inch-pound, 5/16-inch, p/n 8710-1765
— N5511A Phase Noise Test System Users Guidea

If the container or packing material is damaged, the contents should be checked both
mechanically and electrically. If the contents are damaged or defective, contact your customer
support engineer through your local Keysight Technologies Service Center. Keep the shipping
materials for the transport company’s inspection.
User must supply monitor with display port cable.

Unpacking and Inspecting the System
Remove Shipping Cover
The N5511A system is shipped with a protective cover over the front panel.
Remove the cover using a T-20 driver (not included) to remove the 8 screws
attaching the cover to the chassis.
Retain the protective cover and screws for future use should you need to move the system to
another location or return for service. The screws can be inserted into the top of the protective
cover for storage.

System Components
Figure 1-1 Keysight N5511A Phase Noise Test System
The N5511A system is available as a benchtop model. Due to the system’s
flexibility, the hardware in the system varies with the options selected. You may
be installing instruments you already own in the system as well. A typical
N5511A system includes these components:
— N5511A PXIe chassis
— M9037A Controller with removable SSD drive with Windows 10 Professional
— M9551A Data Converter
— M9300A Frequency Reference
— M9550A Phase Detector 1 or 2

Making Connections
Making Connections
Use the information in this section to connect your system hardware.
1. Verify all cables connected to instruments with the appropriate
connectors and adapters, using the following pages in this section.
2. You may connect other assets (in addition to those supplied with the
system) either at this time or after running the confidence test.
3. Lastly, connect the power cord(s) to the AC power supply.
Before connecting the cables to any device:
— Check all connectors for wear or dirt.
— When making the connection, torque the connector to the proper value.
Proper Connector Torque
— Provides more accurate measurements
— Keeps moisture out of the connectors
— Eliminates radio frequency interference (RFI) from affecting your
measurements
The torque required depends on the type of connector. Refer to Table 1-3. Do
not overtighten the connector.
Never exceed the recommended torque when attaching cables.
Make all system hardware connections without AC power applied. Failure to do so may result in
damage to the hardware. Make connections in a properly grounded environment. Keysight
recommends wearing grounding wrist or foot straps. Failure to do so may result in damage to the
hardware.
Keysight Technologies recommends the use of adaptors as connector savers to extend the
lifespan of the test ports on the N5511A Phase Noise Test System.
USE CAUTION WHEN INSTALLING ADAPTORS! Rotation of the adaptor after the connectors are
engaged will damage the connector on the system.

Making Connections
Connecting a Display to your System
The N5511A Phase noise test system does not have a display.
You will have to provide a monitor to view the user interface. Connect a display
port cable to the M9037A controller display port connection and your monitor.
Figure 1-2 M9037A Controller Display Port
Connect the keyboard and mouse to the USB 2.0 ports.
You can use an adapter for other monitor cable types to the display port.
Proper ergonomics should be considered when using accessories such as a keyboard or a mouse.

To power on a racked system
1. Press the system power switch (front, top right of the rack) to the on
position.
2. Verify that all instrument power switches are on.
3. Allow the system to warm up for 30 minutes.
Before applying power, make sure the AC power input and the location of the system meet the
requirements given in Table 2-7 on page 34. Failure to do so may result in damage to the
system or personal injury.
Warm-up Time: The downconverter and RF source instruments contain ovenized oscillators
which must warm up for 30 minutes to produce accurate measurements.
Standby Mode: The RF source uses a standby mode to keep the ovenized oscillator warm when
the instrument is connected (plugged in) to AC power, even when the power switch is in the off
position. To completely shut down the instrument, you must disconnect it from the AC power
supply.

Starting the Measurement Software
The N5510 software is pre-installed on the N5511A Phase Noise system.
Choose the N5510 software icon to launch the user interface.

Keysight Technologies, Inc. has not provided internet security software for this N5511A
Phase Noise Test System. Connecting the PC to a Local Area Network (LAN), without first
installing internet security software (firewall, virus protection, etc) puts both your PC and data at
risk. If you decide to connect the N5511A to a LAN, without first installing internet security
software, you do so at your own risk.
Keysight recommends turning on Windows updates and installing updates when available from
Microsoft.
During the first boot up of the system, you will see the Windows End-User License Agreement
screen. Click Agree to continue. If Disagree is selected, the system will shut down and the
same EULA will appear when the system is booted.

Initial Setup
Starting the Measurement Software
1. To start the program, double-click on the N5510 icon on the desktop
shortcut (shown above), or navigate to the N5510 User Interface through
the Windows start menu. Click Start > All Programs > Keysight N5510 >
N5510 User Interface.
2. When the program starts, the main N5510 measurement window appears
(see Figure 1-5). It shows the phase noise graph.

Initial Setup
Asset Manager
Asset Manager
The Asset Manager adds assets to the N5511A system. All the test sets and
digitizers should be installed at the factory. The procedure is essentially the
same for any asset. We use a source as an example. Adding an asset involves
two steps, once the hardware connections have been made:
— Configuring the asset
— Verifying the server hardware connections.
Configuring an Asset
1. Using Figure 1-7 as a guide, navigate to Asset Manager. For this example
we invoke the Asset Manager Wizard from the N5510 main screen. This is
the most common way to add assets.
Figure 1-7 Navigate to Asset Manager
Reloading or installing a software update will require re-installing all the assets.
If you have not already connected the assets to the system, do so now. Be sure to power off the
system before making all hardware connections other than LAN. (For more information on
connecting assets, see Chapter 3, “System Interconnections”)
Instruments that only have GPIB interface will use the 82357B USB to GPIB Interface Adapter.
