1 Introduction
This chapter provides overall information on the Agilent PSA Series
EMI Receiver Option 239, and describes the EMI compliance
measurements made by the analyzer plus an RF Preselector.
Installation instructions for adding this option to your analyzer are
provided in this section, if you purchased this option separately.

Introduction
What Does the EMI Receiver Do?
What Does the EMI Receiver Do?
The EMI Receiver system consists of an Agilent PSA Series Spectrum
Analyzer, an Agilent RF Preselector, an Agilent Signal Generator for
user alignment, and optional accessories needed to prepare the system
for use. Option 239 is an embedded application in the PSA.
The PSA is used as an EMI receiver, controlling the external RF
Preselector, to perform CISPR compliance EMI measurements to test
conducted and radiated emissions.
Conducted emissions testing focuses on signals, present on the AC
mains, that are generated by the equipment under test (EUT). The test
range for these measurements is typically from 9 kHz to 30 MHz.
Radiated emissions testing looks for signals broadcasted from the EUT
through space. The test range for these measurements is typically from
30 MHz to 1 GHz, depending on the regulation.
You can also perform EMI pre-compliance measurements if you do not
have an RF Preselector. PSA EMI measurement keys are not fully
functional without the RF Preselector.

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 You Have Enough Memory to Load All Your Personality
Options?” on page 11.
2. Install the measurement personality firmware into the instrument
memory. Details follow in “Loading an Optional Measurement
Personality” on page 15.
3. Enter a license key that activates the measurement personality.
Details follow in “Obtaining and Installing a License Key” on page
15.
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.

upgrade kits, visit the following web location:

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 15. 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.
Introduction
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

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/
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 14.
2. The PSA shared libraries require 7.72 MBytes.
3. The PSA 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.
Introduction
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 office, 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 14.
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
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.
