“Tuned RF Level Measurement” on page 74 - Measures the absolute or relative levels of continuous wave RF signals to extremely low levels.
“AM Depth Measurement” on page 82 - Measures the amount of amplitude modulation of an RF carrier.
“FM Deviation Measurement” on page 87 - Measures the frequency deviation of the tuned input signal.
“PM Deviation Measurement” on page 93 - Measures the phase deviation of the tuned input signal.
“Modulation Rate Measurement” on page 99 - Measures the modulation rate of a modulated AM, FM, or PM signal.
“Modulation Distortion Measurement” on page 103 - Measures the modulation distortion applied to the modulated signal by comparing the ratio of harmonic and noise power to total power.
“Modulation SINAD Measurement” on page 107 - Measures the modulation noise and distortion applied to the modulated signal by calculating the ratio of total power to harmonic and noise power.
“Audio Frequency Measurement” on page 111 - Measures the audio frequency of an audio signal applied to the Audio Input port.
“Audio AC Level Measurement” on page 113 - Measures the true RMS level of 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.

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.

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

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

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.

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.

Performing a Relative TRFL Measurement Without the Power Meter
Step 1. Connect, configure and verify the measurement system. See “System Hardware
Connections” on page 44 except do not use the N5532A Sensor module and
connect the DUT output to the PSA RF Input. See “System Configuration” on page 47. Although you are not using the power
meter for this test, you may want to set it up for future for future Power measurements.
Step 2. On the PSA, perform the Auto Align routine by pressing

Step 3. Set the signal source amplitude and frequency . For this example use 0 dBm and 50
MHz.
Step 4. Configure the PSA settings as shown in the table above. Step 5. Press the
Restart key. Error messages will appear because the measuring receiver
defaults to the absolute TRFL measurement where the power meter is required.
Step 6. Press
Meas Setup, Set Ref keys. The measuring receiver is now set to perform the
relative TRFL measurement where a power meter is not required. The error messages will go away, and the Tuned RF Level display should read 0.000dB.
Step 7. Press
Measure Control, select Measure Single and press the Restart key. This will
allow you to control when the measurement is taken so you can assure the source is set to the proper level before beginning the measurement. You will need to press the
Restart key each time you want to make a measurement.

NOTE Do not Preset the PSA, or use the Freque ncy Counter function. If you do, the
instrument will require at least 30 minutes for stabilization.
Step 8. Perform the following steps for each measurement value:
1. Decrease the source power level to the next lower setting and press the key.
NOTE Since the PSA will automatically change ranges and calibrate the ranges as
needed, use step sizes of 10 dB or less.
2. Record the Tuned RF Level result.
3. Continue decreasing the source level and repeating steps 1 and 2.
4. When the source level reaches a power level where the PSA requires the Range 2 change, your measurement will be interrupted and a range calibration will occur. This range calibration will only occur the first time you perform the measurement at a particular frequency and power level using the current PSA settings. There will be no Cal Factor 1 value shown on the display.
If any PSA settings such as IF BW, or if the input frequency is changed, a new range calibration will be required.
5. Continue decreasing the source level and repeating steps 1 and 2.
6. When the source level reaches a power level where the PSA requires the Range 3 change, your measurement will be interrupted and a range calibration will occur.
Restart
7. When all source levels have been measured, calculate the TRFL measurement error. See the Measuring Receiver Personality specifications in the PSA Specification Guide. The Relative Measurement Accuracy specification applies.
NOTE If you wish to start a new series of measurements, and want to clear the Cal Factor
values, press
Measure Setup, and toggle the IF BW to 75 Hz then back to 10 Hz.
Press Set Reference again.
NOTE If the frequency setting of the measurement is changed you must clear the Cal

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.
