1 Introduction

This chapter provides overall information on the Agilent PSA Series WLAN Option 217 and describes the measurements made by the analyzer. Installation instructions for adding this option to your analyzer are provided in this section, in case you purchased this option separately.

Introduction

What Does the Agilent PSA Option 217 Do?

The PSA Option 217 measurement personality can help determine if a WLAN device is working correctly, which has been manufactured according to IEEE standards 802.11a, b, or g. The instrument automatically makes measurements using the measurement methods and limits defined in the following standards documents:

• Supplement to IEEE Standard for Information Technology, IEEE Std 802.11a-1999 (Supplement to ANSI/IEEE Std 802.11, 1999 Edition)

• Higher Speed Physical Layer in the 2.4 GHz Band, IEEE Std

802.11b-1999 (Supplement to ANSI/IEEE Std 802.11, 1999 Edition)

• Higher Speed Physical Layer in the 2.4 GHz Band, IEEE Std

802.11g/D8.2, Jun. 2003 (Supplement to ANSI/IEEE Std 802.11, 1999 (Reaff 2003))

The instrument can test signals that conform to the following standard formats:

• 802.11a: OFDM

• 802.11b: DSSS, CCK, PBCC

• 802.11g: ERP-OFDM, ERP-DSSS, ERP-CCK, ERP-PBCC, DSSS-OFDM

The detailed results displayed by the measurements allow you to analyze WLAN system performance. You may alter the measurement parameters for specialized analysis.

Introduction

Introduction

What Does the Agilent PSA Option 217 Do?

The WLAN measurement personality makes the following measurements:

•Transmit Power

• Transmit Spectrum Mask

• Spectral Flatness (802.11a / 802.11g only)

• Power versus Time (802.11b only)

• Modulation Accuracy

• Power Statistics CCDF

• Spectrum (Freq Domain)

• Waveform (Time Domain) The PSA Option 217 requires PSA Option 122 or 140 (80/40 MHz WB

DIF) to enable the WLAN personality. To measure a WLAN signal above 3 GHz, like a 802.11a signal, PSA Option 123 (High Band Preselector Bypass, above 3 GHz) is required.

For more information on individual measurements, see Chapter 2 ,

“Making Measurements” on page 35.

Introduction

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 You Have Enough Memory to Load All Your Personality Options?” on page 26.

2. Install the measurement personality firmware into the instrument memory. Details follow in “Loading an Optional Measurement

Personality” on page 30.

3. Enter a license key that activates the measurement personality. Details follow in “Obtaining and Installing a License Key” on page

30.

Adding measurement personalities requires the purchase of a retrofit kit for the desired option. The retrofit 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 Internet URL:

Introduction

Do You Have Enough Memory to Load All Your Personality Options?

If you do not have memory limitations then you can skip ahead to the next section “Loading an Optional Measurement Personality” on

page 30. 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 plenty of 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/out of memory as needed. If you only have 48 MBytes of memory, you can upgrade your

hardware to 64 MBytes. To see the size of your installed memory for PSA Series Spectrum

Analyzers:

1. Ensure that the spectrum analyzer is in spectrum analyzer mode because this can affect the screen size.

2. Press the

If you have 48 MBytes of memory, and you want to install more than 3 optional personalities, you may need to manage your memory resources. The following section, “How to Predict Your Memory

Requirements” on page 28, will help you decide how to configure your

installed options to provide optimal operation.

Introduction

Chapter 1 27

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. 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.

For PSA Series see: http://www.agilent.com/find/psa_firmware For PSA select the “Memory Calculator” link. You can try any

combination of available personalities to see if your desired configuration is compatible with your installed memory.

NOTE For PSA: After loading all your optional measurement personalities,

you should have a reserve of ~2 MBytes memory to facilitate mode switching. Less available memory will increase mode switching time. For example, if you employ 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 29.

2. For PSA only: shared libraries require 7.02 MBytes

Introduction

3. For PSA only: recommended mode swap space is 2 MBytes

4. Screens - .gif files need 20-25 kB 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 assessing 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 firmware versions available for downloading:

For PSA, see 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 29.

The approximate memory requirements for the options are listed above. 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

Introduction

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.

2 Making Measurements

This chapter describes procedures used for making measurements of WLAN signals. Instructions to help you set up and perform the measurements are provided, and examples of WLAN measurement results for analysis of various WLAN modulation formats are shown.

Making Measurements

Introduction

This chapter details all WLAN measurements available by pressing the

MEASURE key and also shows example results obtained using the

WLAN measurements. There are eight measurements available in WLAN mode:

•Transmit Power

• Transmit Spectrum Mask

• Power versus Time

•Spectrum Flatness

• Modulation Accuracy

• Power Stat CCDF

• Spectrum (Freq Domain)

• Waveform (Time Domain) All the measurements above are one-button measurements. When you

press the key to select a measurement, it will become active, using settings and displays unique to that measurement. Data acquisition will automatically begin when the equipment is correctly set up and trigger requirements are met. The pass/fail indicators quickly give a visual indication of standards conformance.

You can also customize signal parameters and parameter limits of each measurement, based on user-defined constraints and tolerances. The settings will be used thereafter in making one-button measurements.

NOTE PSA option 217 needs option 122 (80 MHz Wideband Digital IF) or 140

(40 MHz Wideband Digital IF) to enable WLAN personality. Option 123 (Microwave Preselector Bypass) is highly recommended for

making measurements of signals with center frequency above 3 GHz, for instance, 802.11a signals.

Step 2. Press the Meas Setup to change the measurement parameters from

their default conditions. In an OFDM signal, the burst includes training symbols, the signal

field and the data field. To accurately perform a useful CCDF measurement of a device such as a power amplifier (PA), only the signal and data portions of the burst should be included and the measurement must be made on the data portion. This can be done by adjusting the trigger parameters within the CCDF measurement:

First, identify the total length of the burst. This can be done using the Waveform Measurement. You can use

Waveform (Time Domain)

measurement to show the whole burst, place a marker on the left edge of the burst, then use the knob to place a delta marker at the falling edge of the same burst. The length of the burst will display on the top left of Waveform window.You need to elect the correct trigger source to get a stable signal display and then use marker to determine the burst length. For example, you read the burst length as 104 us.

Second, select the

Source

in Meas Setup menu, like Ext Front.

Third, select the appropriate

Power Stat CCDF measurement and set the correct Trig

Meas Interval in Meas Setup menu, like 88

us. Then set trigger offset 16 us for CCDF measurement by pressing

Trig and Ext Front.

The training portion of the OFDM burst occupies the first 16 us, so the CCDF measurement should only analyze the portion of the burst between 16 us and 104 us.

The Spectrum and Waveform measurements available in PSA Option 217 are the same as those available in basic mode. See the PSA Basic Mode User’s Guide Option B7J for more detail on the Spectrum and Waveform measurements, remote commands, front-panel keys, conceptual information and menu maps.

Chapter 2 63

Making Measurements

Using Basic Mode

Basic mode is a standard feature of E4406A Transmitter T esters , and is part of Option B7J for the PSA Series Spectrum Analyzers. Basic mode is not related to a particular communications standard. That is, it does not default to measurement settings that are for any specific standard. You may want to use Basic Mode if you are making measurements on a signal that is not based on a specific digital communications standard.

Basic Mode in E4406A VSA Series Transmitter Testers

There are five generic measurements available under the MEASURE key in Basic mode:

• Adjacent Channel Power (ACP)

• Channel Power

• Power Statistics CCDF

• Spectrum measurement (frequency domain).

• Waveform measurement (time domain) The ACP, Channel Power, and Power Stat CCDF measurements are

fully described in the VSA Series User’s Guide. Please refer to that manual for complete information on these measurements.

Spectrum and Waveform Measurements

These measurements provide a spectrum measurement mode that is similar to a standard spectrum analyzer , and a waveform measurement mode that is similar to a microwave oscilloscope. Unlike those standard analyzers, these measurements are optimized for digitally modulated signals, so they can be used to output the measured I/Q data.

For your convenience, Spectrum and Waveform measurements are also available in this mode, with the same functionality, so you can refer to the sections included in this chapter for information about using them.

Basic Mode in PSA Series Spectrum Analyzers

There are two generic measurements available under the MEASURE key in Basic mode:

Restart to make another measurement and observe the results.

Re-adjust the ADC as necessary to obtain a valid measurement.

• Error Code 16 “Input overload”

This error means that your measurement has erroneous results due to the excessive input power level. To correct this condition, the input signal level must be reduced by using the internal and/or external attenuator.

Press the

Mode Setup, Input, Input Atten keys to enter an attenuation

value to reduce the transmitted power from the MS. This allowable range is up to 40 dB.

To attenuate more than 40 dB, connect your external attenuator between the RF INPUT port and the DUT. Be sure to add its attenuation value to the readings of the measurement result.

To automate this calculation, press the

Mode Setup, Input, Ext Atten

keys to enter the additional attenuation value. The allowable range is up to 100 dB. The power readings of the measurement will take into account the external attenuation value.

• Error Code 601 “Signal too noisy”

This error means that your input signal is too noisy to capture the correct I/Q components. To make a more stable measurement the trigger source may need to be set to

Frame, for example.

• Error Code 604 “Can not correlate to input signal”

This error means that the tester has failed to find any active channels in the input signal as specified. To improve the correlation some critical parameter needs to be adjusted, like the input signal level or scramble code, for example.

Accesses the measurement and sets the instrument settings to the defaults. Averaging is turned on and set to 10. The instrument is put in single measurement mode. It does not initiate a measurement. Use INIT:IMM to make one measurement.

every error/status bit change that has occurred will be returned with a *ESR? query. You must set the value of *ESE to choose only the bits/status that you want returned.

For these modes, only one trigger source can be selected and it will be common across the modes. Also, only one value can be set for the trigger delay, level, or polarity.

Basic, cdmaOne, cdma2000, 1xEV-DO, W-CDMA, GSM, EDGE, NADC, PDC Modes

Accesses the measurement and sets the instrument settings to the defaults. If you were already in single measurement mode, it takes one measurement and then waits. If you were in continuous measurement mode it continues to measure.

Default is 0 which means that none of the error/status bit changes that have occurred will be returned with a *ESR? query. Yo u must set the value of *ESE to choose the bits/status that you want returned.

For these modes, a unique trigger source can be selected for each mode. Also, each trigger source can have unique settings for the its delay, level, and polarity.

Saving and recalling traces

Traces can only be saved when in the Spectrum Analysis mode (MMEM:STOR:TRAC). This is because the instrument state must be saved along with the trace data and the state data varies depending on the number of modes currently available in the instrument.

Measure Commands:

:MEASure:<measurement>[n]?

This is a fast single-command way to make a measurement using the factory default instrument settings. These are the settings and units that conform to the Mode Setup settings (e.g. radio standard) that you have currently selected.

• Stops the current measurement (if any) and sets up the instrument for the specified measurement using the factory defaults

• Initiates the data acquisition for the measurement

• Blocks other SCPI communication, waiting until the measurement is complete before returning results.

• After the data is valid it returns the scalar results, or the trace data, for the specified measurement. The type of data returned may be defined by an [n] value that is sent with the command.

ASCII is the default format for the data output. (Older versions of Spectrum Analysis and Phase Noise mode measurements only use ASCII.) The binary data formats should be used for handling large blocks of data since they are smaller and faster than the ASCII format. Refer to the FORMat:DATA command for more information.

If you need to change some of the measurement parameters from the factory default settings you can set up the measurement with the CONFigure command. Use the commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems to change the settings. Then you can use the READ? command to initiate the measurement and query the results. See

Figure 1.

If you need to repeatedly make a given measurement with settings other than the factory defaults, you can use the commands in the SENSe:<measurement> and CALCulate:<measurement> subsystems to set up the measurement. Then use the READ? command to initiate the measurement and query results.

Measurement settings persist if you initiate a different measurement and then return to a previous one. Use READ:<measurement>? if you want to use those persistent settings. If you want to go back to the default settings, use MEASure:<measurement>?.

Configure Commands:

:CONFigure:<measurement>

This command stops the current measurement (if any) and sets up the instrument for the specified measurement using the factory default instrument settings. It sets the instrument to single measurement mode but should not initiate the taking of measurement data unless INIT:CONTinuous is ON. After you change any measurement settings, the READ command can be used to initiate a measurement without changing the settings back to their defaults.

The CONFigure? query returns the current measurement name.

Chapter 3

Front-Panel Key and SCPI Command Reference

Measure

Fetch Commands:

:FETCh:<measurement>[n]?

This command puts selected data from the most recent measurement into the output buffer. Use FETCh if you have already made a good measurement and you want to return several types of data (different [n] values, e.g. both scalars and trace data) from a single measurement. FETCh saves you the time of re-making the measurement. You can only FETCh results from the measurement that is currently active, it will not change to a different measurement.

If you need to get new measurement data, use the READ command, which is equivalent to an INITiate followed by a FETCh.

The scalar measurement results will be returned if the optional [n] value is not included, or is set to 1. If the [n] value is set to a value other than 1, the selected trace data results will be returned. See each command for details of what types of scalar results or trace data results are available. The binary data formats should be used for handling large blocks of data since they are smaller and transfer faster then the ASCII format. (FORMat:DATA)

FETCh may be used to return results other than those specified with the original READ or MEASure command that you sent.

Front-Panel Key and SCPI Command

Reference

INITiate Commands:

:INITiate:<measurement>

This command is not available for measurements in all the instrument modes:

• Initiates a trigger cycle for the specified measurement, but does not output any data. You must then use the FETCh<meas> command to return data. If a measurement other than the current one is specified, the instrument will switch to that measurement and then initiate it.

For example, suppose you have previously initiated the ACP measurement, but now you are running the channel power measurement. If you send INIT :ACP? it will change from channel power to ACP and will initiate an ACP measurement.

• Does not change any of the measurement settings. For example, if you have previously started the ACP measurement and you send INIT:ACP? it will initiate a new ACP measurement using the same instrument settings as the last time ACP was run.

• If your selected measurement is currently active (in the idle state) it triggers the measurement, assuming the trigger conditions are met. Then it completes one trigger cycle. Depending upon the measurement and the number of averages, there may be multiple data acquisitions, with multiple trigger events, for one full trigger cycle. It also holds off additional commands on GPIB until the acquisition is complete.

READ Commands:

Front-Panel Key and SCPI Command

:READ:<measurement>[n]?

• Does not preset the measurement to the factory default settings. For example, if you have previously initiated the ACP measurement and you send READ:ACP? it will initiate a new measurement using the same instrument settings.

• Initiates the measurement and puts valid data into the output buffer . If a measurement other than the current one is specified, the instrument will switch to that measurement before it initiates the measurement and returns results.

For example, suppose you have previously initiated the ACP measurement, but now you are running the channel power measurement. Then you send READ:ACP? It will change from channel power back to ACP and, using the previous ACP settings, will initiate the measurement and return results.

• Blocks other SCPI communication, waiting until the measurement is complete before returning the results

If the optional [n] value is not included, or is set to 1, the scalar measurement results will be returned. If the [n] value is set to a value other than 1, the selected trace data results will be returned. See each command for details of what types of scalar results or trace data results are available.

n = 7 Corrected measured trace returns series of floating point numbers that

alternately represent I and Q pairs of the corrected measured trace. The magnitude of each I and Q pair are normalized to 1.0, when the IQ Normalize is turned on. The first number is the in-phase (I) sample and the

second is the quadrature-phase (Q) sample. n = 8 Returns Decoded Bits n = 9 Returns 4 comma-separated scalar values of the pass/fail (0.0 = passed, or

1.0 = failed) results determined by testing the following items. And the

pass/fail is for the peak-hold value. Because the test on peak-hold value

should be greater than the average value, if it fails on the average, it will

fail on peak-hold.
