ntroduction

Standard Agilent Technologies ESG family RF signal generators incorporate a road array of capa ilities for testing

oth analog and digital communications systems. Adding flexi le options provides a test solution that will evaluate

the performance of a communication system to the requirements of nearly all current and proposed air interface

standards. Many test functions can e customized to meet the needs of proprietary and other nonstandard wireless

protocols as well. This guide descri es how you can configure your instrument to address a wide variety of tests—

from altering nearly every aspect of a digital signal or signal operating environment to creating experimental signals.

This flexi ility, along with an architecture that accepts future enhancements, makes the ESG family an excellent

choice for wireless communication system testing now and in the future.

ESG family of

RF signal generators

The ESG family consists of four

series:

ESG-A series: analog instruments

ESG-AP series: analog instruments

with high spectral purity.

ESG-D series: digital and analog

instruments.

instruments with high spectral

purity.

Refer to ta le 1 for a list of the

model num ers and their associated

capa ilities including frequency

range, spectral purity, and modula-

tion capa ility.

In keeping pace with ever-changing

digital communication standards,

Agilent Technologies is the leading-

edge supplier of the latest signal-

generator technology. To meet your

evolving needs, Agilent Technologies

constantly enhances the ESG family

with the option of turning off any

com ination of tones. Adjust the

frequency spacing etween the tones

and the phase of each individual

tone to maximize measurement

accuracy.

gated, or segment advance triggering

with up to a one-hour delay time.

Markers1

Trigger other events at specific points

in the playbac of a waveform.

Define marker locations in a

segment during the waveform-

generation process, or from the

front panel. Activate or deactivate

markers for each segment using the

sequence ta le editor. A marker

can also e tied to the RF lanking

feature of the ESG to simulate

ursted signals.

www.agilent.com/find/esg.

Option UND (continued)

Bluetooth1

Test Bluetooth components and systems

with standards-compliant signals.

Specify Bluetooth device address,

active mem er address, and payload

data for a DH1 packet type. Three

payload data formats are availa le:

8- it pattern, truncated PN9 sequence,

and continuous PN9 sequence. When

continuous PN9 is selected, clock and

gate signals with delay control are

also generated. These signals can e

used to extract the continuous PN9

payload data from the DH1 packet

when performing receiver it-error-

rate tests using Option UN7 (internal

BER analyzer).

The Bluetooth personality offers a

variety of impairments to synthesize

non-ideal signals for receiver testing.

Availa le impairments include modu-

lation index, sym ol timing error,

carrier frequency offset, linear and

sinusoidal carrier frequency drift,

and AWGN. Define the urst shape y

specifying the num er of sym ols per

ramp to test a receiver’s response to

different transmitter urst profiles.

Option UN8 also offers a Bluetooth

predefined modulation format, how-

ever, Bluetooth packets are not creat-

ed. Instead a data pattern is selected

or downloaded to Option UN8 and

that data pattern is then Bluetooth

modulated.

For more information, refer to

Performing Bluetooth RF Measure-

ments Today, Application Note 1333,

Multicarrier1

Characterize multicarrier compo-

nents y applying multiple digitally

modulated carriers. Generate up to

64 modulated carriers in a 15 MHz

andwidth. Adjust the frequency and

power offset of each carrier to meet

test requirements. Select from pre-

defined modulation formats or create

a custom format. Define a custom for-

mat y choosing the modulation type,

filter and sym ol rate. Custom modu-

lation types include a variety of PSK,

QAM, FSK and MSK. The data used

on each carrier is random.

Pre-defined formats include:

1. New features available with firmware revision B.03.20 and higher.

Real-time /Q baseband

generator, Option UN8

Option UN8 simulates mo ile or ase

station transmissions of common digi-

tal communication standards. The

real-time I/Q ase and generator

supports DECT, GSM, NADC, PDC,

PHS, TETRA, and CDMA communi-

cation standards. Data for these

standards can e generated internal-

ly or supplied externally. After set-

ting the frequency and amplitude

of your signal, TDMA standards

are availa le with the touch of one

utton. Alternatively, you can mix

and match modulation types, sym ol

rates and filters to create custom

platforms for developing new or

proprietary communication standards.

Description

Option UN8 is one of two internal

ase and generator cards for the

ESG family. This real-time I/Q

ase and generator uilds digitally

modulated signals y mixing and

matching modulation types, sym ol

rates and filters. It is provided on

a user-installa le card that can e

added to the B version of any existing

ESG or any new instrument.

Different personalities may e

purchased separately to provide

specific modulation formats.

Option UN8 is a standard option

with 1 Mega yte of RAM to store

custom data. To increase the RAM

to 8 Mega ytes, Option UN8 can e

ordered in conjunction with Option

UN9 (Option UN8 consists of two

cards). Option UN9 replaces one of

these cards to provide 8 Mega ytes

of RAM.

Key features

ntuitive menu

Easy selection of predefined

standards.

Common communication standards

(NADC, GSM, PDC, PHS, DECT,

TETRA) are introduced at the first

menu level. The second level provides

flexi le access for asic configuring

of data, timeslots, and framing.

Mix and match modulation types,

symbol rates and filters

Create custom platforms for

developing new or proprietary

communication standards.

The real-time I/Q ase and generator

(Option UN8) ena les simple genera-

tion of complex signals. It is easy to

mix and match a modulation type

from one standard with a filter type

from another. For example, generate

a CDPD signal y selecting an NADC

format and su stitute a 0.5 GMSK

modulation instead of the standard

p/4 DQPSK modulation or generate

PWT, a DECT variant, y su stituting

π/4 DQPSK modulation in the DECT

standard. Implement and recall

non-standard solutions easily.

Unlimited modulation types using FSK,

/Q and differential table editors

Define modulation formats specific

to application needs or impair the

standard modulation formats for

stress testing.

Select modulations from a menu of

PSK, MSK, QAM or FSK modulation

types.

Define the constellation of your choice

with up to 16 values of I and Q. Add

impairments such as origin offset,

EVM, phase error, and quadrature

error to the I/Q definition to test

design ro ustness. Before generating

the modulated signal, display the I/Q

state map for a quick visual check.

You can build asymmetric FSK formats such as FLEX with the FSK table editor.

Customize modulations or perform margin testing with the /Q table editor.

Option UN8 (continued)

Symbol rates up to 12.5 MHz

Specify rates to cover the existing

communications systems and new

third-generation systems.

If you want to create a new modula-

tion scheme, the real-time I/Q

ase and generator sym ol rate

can e specified from 50 Hz to

12.5 MHz. This range covers existing

communications systems such as

GSM at 270.833 Ksps and NADC at

24.3 Ksps and new emerging wide-

and communication systems.

nternal data generator

Generate PN (pseudo-random noise)

sequences or repeating patterns.

Internally generate PN9, PN11,

PN15, PN20 and PN23 (pseudo-

random noise) sequences or fixed

4- to 64- it repeating patterns. Other

data patterns can e downloaded

into memory or generated in real-time,

through the data/clock/sync inputs.

Burst shaping

Create custom burst to simulate

unique traffic patterns.

Adjust urst rise/fall time and delay

through softkeys under the chosen

TDMA protocol. Customized or

standard ursts may also e

provided externally through the

external 1 input.

Select or build your own filters to

control bandwidth and modulation

quality.

Nyquist, root Nyquist, Gaussian and

IS-95 FIR filters are all availa le.

or the BT ( andwidth time product)

for a Gaussian filter from 0.1 to 1.

The FIR ta le editor ena les you

to uild your own filters or add

impairments such as static fading

in the channel. Test new designs in

the manufacturing environment y

using the same filter and signal

impairments. Changing the filter

factor can also e used to intentional-

ly change signal characteristics such

as EVM. This is a useful tool to test

receivers under real-life conditions.
