an external signal.
• “Audio Distortion Measurement” on page 115 - Measures the amount of audio
distortion applied to the audio signal by comparing the ratio of harmonic and
noise power to fundamental power.
• “Audio SINAD Measurement” on page 117 - Measures the amount of audio
SINAD to the audio signal by comparing the ratio of fundamental power to
harmonic and noise power.
• “Auto Carrier Frequency Triggering and CCITT Filtering” - As of PSA
firmware revision A.11.08 these are available in Option 233 as standard
features. Previously, these features were only available with licensed Options
23A and 23B. For backwards compatibility, it may be necessary to license
these two options so they will appear on the Show System screen, or can be
queried using the *OPT? SCPI command. Please contact Agilent Technologies
if license keys are required.

Installing Optional Measurement Personalities
Installing Optional Measurement Personalities
When you install a measurement personality, you need to follow a three step
process:
1. Determine whether your memory capacity is sufficient to contain all the
options you want to load. If not, decide which options you want to install now,
and consider upgrading your memory. Details follow in “Do Y ou Have Enough
Memory to Load All Your Personality Options?” on page 31.
2. Install the measurement personality firmware into the instrument memory.
Details follow in “Loading an Optional Measurement Personality” on page 35.
3. Enter a license key that activates the measurement personality. Details follow
in “Obtaining and Installing a License Key” on page 35.
Adding measurement personalities requires the purchase of an upgrade kit for the
desired option. The upgrade kit contains the measurement personality firmware
and an entitlement certificate that is used to generate a license key from the
internet website. A separate license key is required for each option on a specific
instrument serial number and host ID.
For the latest information on Agilent Spectrum Analyzer options and upgrade kits,
visit the following web location:
http://www.agilent.com/find/sa_upgrades
Do You Have Enough Memory to Load All Your Personality Options?
If you do not have memory limitations, go to the next section “Loading an
Optional Measurement Personality” on page 35. If after installing your options you
get error messages relating to memory issues, you can return to this section to learn
more about how to optimize your configuration.
If you have 64 MBytes of memory installed in your instrument, you should have
enough memory to install at least four optional personalities, with enough memory
for data and states.
The optional measurement personalities require different amounts of memory. So
the number of personalities that you can load varies. This is also impacted by how
much data you need to save. If you are having memory errors you must swap the
applications in or out of memory as needed. If you only have 48 MBytes of
memory, you can upgrade your hardware to 64 MBytes.
Additional memory can be added to any PSA Series analyzer by installing Option
115. With this option installed, you can install all currently available measurement
personalities in your analyzer and still have memory space to store more state and
trace files than would otherwise be possible.

Introduction
Introduction
Installing Optional Measurement Personalities
How to Predict Your Memory Requirements
If you plan to install many optional personalities, you should review your memory
requirements, so you can determine whether you have enough memory (unless you
have a PSA Series with Option 115). There is an Agilent “Memory Calculator”
available online that can help you do this, or you can make a calculated
approximation using the information that follows. You will need to know your
instrument’s installed memory size as determined in the previous section and then
select your desired applications.
NOTE If you have a PSA Series analyzer with Option 115, there is adequate memory to
install all of the available optional personalities in your instrument.
To calculate the available memory on your PSA, see:
http://sa.tm.agilent.com/PSA/memory/
Follow the steps on the web page to see if your desired configuration is compatible
with your installed memory.
NOTE After loading all your optional measurement personalities, you should have a
reserve of ~2 MBytes of memory to facilitate mode switching. Less available
memory will increase mode switching time. For example, if you use excessive free
memory by saving files of states and/or data, your mode switching time can
increase to more than a minute.
You can manually estimate your total memory requirements by adding up the
memory allocations described in the following steps. Compare the desired total
with the available memory that you identified in the previous section.
1. Program memory - Select option requirements from the table “Measurement
Personality Options and Memory Required” on page 34.
2. Shared libraries require 7.72 MBytes.
3. The recommended mode swap space is 2 MBytes.
4. Screens - .gif files need 20-25 kBytes each.
5. State memory - State file sizes range from 21 kB for SA mode to 40 kB for
W-CDMA. The state of every mode accessed since power-on will be saved in
the state file. File sizes can exceed 150 kB each when several modes are
accessed, for each state file saved.
TIP State memory retains settings for all states accessed before the Save State
command. To reduce this usage to a minimum, reduce the modes accessed before
the
Save State is executed. You can set the PSA to boot into a selected mode by
accessing the desired mode, then pressing the
System, Power On/Preset, Power On
keys and toggle the setting to Last.

Memory Upgrade Kits
The PSA 64 MByte Memory Upgrade kit part number is E4440AU-ANE. The
PSA Compact Flash Upgrade kit part number is E4440AU-115.
For more information about memory upgrade kits, contact your local sales or
service office, or see:
http://www.agilent.com/find/sa_upgrades
Loading an Optional Measurement Personality
You must use a PC to load the desired personality option into the instrument
memory. Loading can be done from a firmware CD-ROM or by downloading the
update program from the internet. An automatic loading program comes with the
files and runs from your PC.
You can check the Agilent internet website for the latest PSA firmware versions
available for downloading:
http://www.agilent.com/find/psa_firmware
NOTE When you add a new option, or update an existing option, you will get the updated
versions of all your current options as they are all reloaded simultaneously. This
process may also require you to update the instrument core firmware so that it is
compatible with the new option.
Depending on your installed hardware memory, you may not be able to fit all of
the available measurement personalities in instrument memory at the same time.
You may need to delete an existing option file from memory and load the one you
want. Use the automatic update program that is provided with the files. Refer to the
table showing “Measurement Personality Options and Memory Required” on
page 34. The approximate memory requirements for the options are listed in this
table. These numbers are worst case examples. Some options share components
and libraries, therefore the total memory usage of multiple options may not be
exactly equal to the combined total.
Obtaining and Installing a License Key
If you purchase an optional personality that requires installation, you will receive
an “Entitlement Certificate” which may be redeemed for a license key specific to
one instrument. Follow the instructions that accompany the certificate to obtain
your license key.
To install a license key for the selected personality option, use the following
procedure:
NOTE You can also use this procedure to reinstall a license key that has been deleted
during an uninstall process, or lost due to a memory failure.

Setting up the System
Step 2. Set up the N5531S Measuring Receiver system by correctly connecting the PSA,
Power Meter, Sensor Module and Unit Under Test (UUT). See Figure 2-1,
“Hardware Setup Block Diagram,” on page 44.
CAUTION While connecting the sensor module to the UUT, make sure you follow the
instructions below:
1. Before connecting a signal to the sensor module, make sure the sensor module
can safely accept the signal level provided. See Sensor Module Users Guide to
view the signal level limits.
2. Turn only the connector sleeve portion of the sensor module. Damage can
occur if torque is applied to the sensor module body.
3. If possible, ensure the sensor rests flush against a desktop or other support. This
helps prevent mechanical damage to the sensor and UUT RF OUT connector.
See Figure 2-3, “Connecting the Sensor Module to the UUT,” on page 45.
4. Maximum torque at the connector should NOT exceed 12 in-pound (135 Ncm)
for the Type-N connector or 8 in-pound (90 Ncm) for the 3.5-mm or 2.4 mm
connector to avoid damage to the connector.
Step 3. Connect power cords to the PSA, Power Meter and UUT.
Figure 2-1, “Hardware Setup Block Diagram,” on page 44 illustrates the system
hardware after being set up and connected with UUT and figures below illustrate

need to repeat the Power Meter Calibration. See Power Meter Guide.
When to Recalibrate
• When you change the current sensor to a different type (for example, from
N5532A Option 504 to N5532A Option 518), and a Power measurement is
selected, the Measuring Receiver displays the RECAL or UNCAL annunciator.
• When you change the current sensor to a same type, but a different one (for
example, from N5532A Option 504 to another N5532A Option 504), and a
Power measurement is selected, the Measuring Receiver DOES NOT recognize
the need for recalibration although a recalibration should be performed.
• If you are in doubt about whether the calibration factors match the power
sensor, you should recalibrate.
File Operations
This section describes file operation features for the Measuring Receiver.
File Operations for Power Sensor Calibration Factors

Most of the SCPI commands for the calibration factors file operations are
consistent with those in the MMEMory subsystem, for example, Catalog, Delete,
etc., except for Save and Load.
File Operations for Tuned RF Level Calibration Factors
TRFL measurements can support store and recall functions for the convenience of
repetitive TRFL measurements at many different frequencies. Because the cal
factors are dependent on the instrument setting and TRFL measurement setting, cal
factors are saved into a state file with instrument and measurement settings. When
you recall the cal factors, not only the cal factors are recalled, but all of the
instrument and measurement settings are recalled.
NOTE Cal factor values will become stale due to time and temperature drift, and
following the PSA align routines.

PSA Range Calibration
Only the Tuned RF Level measurements require the PSA range calibration.
As the signal level into the PSA is decreased, the signal to noise ratio changes not
only because the signal is closer to the noise but because some of the internal
settings of the PSA change to optimize the measurement. The measuring routine in
the PSA calculates the approximate power level a range calibration is needed
based on S/N. When the signal level at the PSA reaches this range calibration
power, the calibration routine makes measurements in both the current range and
the next range. A Cal Factor value is generated and is used to correct the
measurement.
There are two range calibrations; Range 1 to Range 2 and Range 2 to Range 3.
The range calibration procedure can be a separate process that you perform before
you begin the TRFL measurement on your UUT (the process outlined here), or the
range calibration can be performed during the TRFL measurement of the UUT.
The range calibration can be triggered automatically by the PSA, or it can be
triggered manually. Press
Meas Setup, Range Switching, to select Auto or Man.
Auto mode will probably be used most of the time. In Man mode, a Recal message
appears on screen alerting the user a range calibration is required. The range
calibration will be held off until you press
TRFL Calibrate. There may be
situations slightly above the calculated range switch point where you want to
continue making measurements in the current range.
NOTE The range calibration “assumes” the power level of the current range is close to the
range switch point. Example: if the PSA calculates the range 2 to range 3 switch
point at − 80 dBm, the range calibration must be done within a few dB of − 80
dBm. Therefore, it is important to step the power level down in steps of 10 dB or
less to allow optimum calibration.
If you chose to allow the range calibration to occur as part of the TRFL
measurement of the UUT, the UUT measurement will be interrupted while the
calibration takes place.

Protecting Against Electrostatic Discharge
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:
• 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.
WARNING Do not use the first three techniques listed above when working on circuitry
with a voltage potential greater than 500 volts.
• 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).

Frequency Counter Measurement
Frequency Counter Measurement
The Frequency Counter measurement is used to determine the center frequency of
an unmodulated RF carrier, or of a CW audio signal. It is the default measurement
of the personality, and its result is used in many subsequent measurements.
Therefore, connection setup and execution of this measurement is important to
assure good results for follow-on measurements.
This procedure describes how to make a Frequency Counter measurement. In this
measurement example, a signal generator is the UUT and is adjusted to deliver a
test signal. The Frequency Counter measurement is used to measure and display
the frequency of the signal.
If the nominal frequency of the signal under test is known, the Measuring Receiver
can be manually tuned to that frequency to make the Frequency Counter
measurements. Manual tuning is particularly useful if the signal level is so low that
automatic tuning may have difficulty finding the signal. Manual tuning also allows
faster measurements when the frequency of the input signal is much higher than
100 MHz.
CAUTION To make the Frequency Counter measurement, make sure you have turned off the
signal modulation. After measuring the carrier frequency, turn on the signal
modulation and continue making other modulation measurements.
NOTE You can make F requency Coun ter measurem ents without a Power Meter since it is
the PSA that measures the RF Frequency.

signal.
RF Power quantifies the output level, in an absolute term, of a signal generator or
an attenuator being calibrated. This is a common measure for broadband
RF/microwave signal qualification.
NOTE The measurement default is to use a Power Meter with a Sensor Module to make
the RF Power measurement. The Power Meter measures the RF Power and returns
the result to the PSA.
Alternatively, you can measure the RF Power with only the PSA. Press

Tuned RF Level Measurement
Tuned RF Level Measurement
This procedure describes how to make a Tuned RF Level measurement. In this
measurement example, a signal generator is the UUT and is adjusted to deliver a
test signal. Tuned RF Level measurement is used to measure that signal. The
source power is stepped down and the PSA displays the Tuned RF Level of the
signal.
Unlike RF Power measurements, which measure total power across a wide
frequency band, the Tuned RF Level measure ment requires the PSA to be tuned to
the frequency of interest and is capable of measuring low power levels. This is
particularly useful when a step attenuator or a signal generator is tested for its step
accuracy of power output with incremental changes.
NOTE You need a Power Meter with a Sensor Module to make an “abs olute” Tuned RF
Level measurement. The Power Meter provides the initial absolute power
reference for the PSA.
Alternatively, you can make a relative Tuned RF Level measurement without a
Power Meter.
Avoid Residual Responses
As the displayed average noise level of a spectrum analyzer becomes very low,
residual responses can be revealed. This is important when measuring signals in
the –130 to –140 dBm range. These residual responses are rare and almost always
occur at multiples of 50 MHz.They are caused by various internal clocks and
mixing products. Residuals are present on all modern spectrum analyzers and will
limit the dynamic range of the analyzer when the residual appears at, or very close
to, the signal to be measured.
To determine if a residual is present, place the spectrum analyzer in spectrum
analysis mode, terminate the input with a 50 ohm load, and use the following
settings:
Frequency: the desired measurement frequency
Span: 1 kHz
RBW: 3 Hz
Ref Level: –60 dBm
Avg Number: 10
If a residual is identified, choose a measurement frequency to avoid the residual. A
spacing of two resolution bandwidths away from the residual will provide 48 dB of
attenuation. For example, if the default 10 Hz RBW is used, make your
measurement ±20 Hz away from a residual.

this phase ramp is the goal of auto carrier frequency.
The default is Auto Carrier frequency On, and in this state, the analyzer uses an
algorithm to estimate the carrier frequency. If you lock the analyzer to an external
reference which is coherent with your carrier, no carrier frequency estimation is
required, and you do not need to select auto carrier frequency . W ithout auto carrier
frequency, the analyzer uses its center frequency to determine the carrier frequency
of your signal.
Considerations When Using Auto Carrier Frequency:
The following situations can bias the phase ramp estimation and the Auto carrier
should be turned off:
• Low frequency modulation, such as a periodic signal with fewer than 10 cycles
over the time record.
• Phase discontinuities present in digital communications formats.
• Transients, such as carrier turn-on in the middle of the time record. Another
example is when measuring the settling time of a VCO or a synthesizer. This
causes a DC shift in the demodulators output if it is trying to estimate the
carrier frequency before it is stable.

Modulation Rate Measurement
This procedure describes how to make a Modulation Rate measurement. In this
measurement example, a signal generator is the UUT and is adjusted to deliver a
test signal. Modulation Rate measurement is used to measure and display the
modulation rate of the signal.
NOTE You can make Modulation Rate measurements without a Power Meter since it is
the PSA that measures the Modulation Rate.
Measurement Procedure
NOTE For AM/FM/PM modulated signals, the modu lation may distort the origi nal signal
spectrum and the instrument may not determine the correct carrier frequency.
Since the result of this measurement is used to calculate follow-on measurements,
the alternative is to input the carrier frequency manually by pressing
Channel
key . This avoid th e need to make Frequency Counter measurement before
other measurements.

CAUTION Press the Restart key to optimize the measuring receiver configuration if you make
any changes to the UUT or to the measuring receiver settings after you make your
first measurement.
Step 1. Setup the measurement system. See “System Hardware Connections” on page 44.
To measure the Modulation Rate, you do not have to perform the Power Meter
calibration.
Step 2. Make sure you have selected
Measuring Receiver mode in the MODE key menu.
Step 3. Adjust the signal generator to the desired settings for your test.
Step 4. Perform a Frequency Counter measurement to accurately determine the center
frequency of your signal.
When the measurement is completed, the measurement result will display.
Step 5. Press
Modulation Rate key. Wait for the measurement to be completed.
When the measurement is completed, the measurement result will display.
