Application E xamples

The need for performance arbitrary waveform generation is broad and
spans over a wide array of applications. With the AWG7000 Series,
Tektronix’ 3
represent a new benchmark in performance, sam ple rate, signal fidelity,
and timing resolution.

The ability to create, generate, or replicate either ideal, distorted, or
“real-life” signals is essential in th e design and testing process. Signal
generati
multilevel, and mixed signals; wideband RF, and fast-changing signals are
just some of the cap abilities of the AWG7000 Series.

Pre/De-Emphasized Signal Generation

With increasing transmission speeds and to compensate for frequency
characteristics of “lossy” media, the technique of pre/de-emphasis is
increasingly applied. Serial data standards such as PCI Express and others
have also included pre/de-emphasis tests as a requirement to meet the
respective compliance test specification.

The basic the ory of pre-empha sis is that for any series of bits of the same
value, the first bit always has a higher voltage level than the following
bits. By
compensated thus the signal fidelity at the receiver side increased.

serial data standards. It also enables users to generate 3-level signals as
required for SATA Out-of-Band (OOB) testing .

The direct generation of such signals provides an increased signal quality
and avoids cumbersome signal generation using multiple channels and a
power combiner. See Figure 1.

Multilevel Signal Generation

The requirements for serial interfaces are continuously increasing. Higher
and higher data rates are required, and the performance of cables and
circuits is moving closer to their theoretical limits. One technique to increase
the data rate without increasing the transition rate is by applying multilevel
signals, wherein a signal can assume more than the standard binary 2
levels.

ultilevel signaling one can think of multilevel discrete amplitudes of a

signal. This phenomenon is known as Pulse Amplitude Modulation or PAM.
A 4PAM signal, a signal with 4 different amplitudes, increases the data rate
by four without increasing the transition rate of the signal. Multilevel signals
are not only applied for data transmission. Multilevel memory chips, storing
more than a single bit in an individual memo ry element, are being produced

Signal Generation for Storage Device Testing

Increasing capacity requirements for storage devices leads to the
development of new and faster read-and-write strategies for magnetic as
well as optical storage devices. Multilevel coding of data for storage on
optical disks is also being considered as an efficient way to increase storage
capacity.

The AWG7000 Series, with its ability to generate an accurate reproduction
of the readandwrite signals, enables users to design, develop, and test the

orage devices. With sample rates up to 20 GS/s, and the generation

of up to 6 signals (2 analog plus 4 marker) with a clock timing resolution of
100 ps, the AWG7000 Series represents a new benchmark in the industry.

Wideband RF-signal Generation

image require test equipment that can provide enough sample rate and

resolution to recreate even the most complex RF behavior. The latest digital
RF technologies often exceed the capa bilities of current test equipment to
generate wide-bandwidth and fast-changing signals that are increasingly
seen in many wireless applications such as radar, UWB, and others.

The AWG7000 Series enables the direct generation of RF signals and
their output throu gh the D/A converter for signals up to a carrier frequency
of 5 GHz and a bandwidth of 5.8 GHz. The direct generation of IF or
RF signal

s avoids I/Q degradations and lengthy adjustments associated
with traditional generation using I/Q modulators. The AWG7000 Series with
its maximum sample rate of 20 GS/s is the sole solution that allows a direct
RF signal ge neration for up to 5 GHz. See Figure 4.

RFXpress (RFX100)

RFXpress is a s of tware package that synthesizes digitally modulated
baseband, IF, and RF signals. It takes IQ, IF, and RF signal ge nerat ion to
the next level and fully exploits the wideband signal generation capabilities
of Arbitrary Waveform Generators (AWGs). Supporting a wide range of
modulations, as well as the symbol map functions, the software allows you
to define your own modulation.

UWB-WiMedia signal creation, a software module for RFXpress, has the
capability to digitally synthesize and generate RF signals in Band Groups 1
and 2 of the UWB s pectrum. As per the latest WiMedia specification, signals
will band hop in real-time over 1.5 GHz modulation bandwidth including all

the different preamble synchronization sequences, cover se quences, TFCs,
and band g
with band hopping in eith er IQ or IF. The conformance mode enables you
to generate all signals that co nform to WiMedia’s specifications, while the
custom mode allows you to adjust the signals for stress and margin testing.

roups. All six band groups (BG1 to BG6) can be generated

SerialXpress®(SDX100)

SerialXpress enables creation of exact waveforms required for
thorough and repeatable design validation, margin/characterization, and
conformance testing of high-speed serial data receivers. It considerably
simplifies the signal creation and Jitter simulations, thus reducing overall

ment and test time. In addition to supporting generation of Jitter

develop
(Random, Periodic ( sinusoidal), ISI, and DCD) SerialXpress also supports
SSC, pre-emphasis, and noise addition. This allows the user to create a
combination of various impairments simultaneously to stress the receiver.

Both RFXpress and SerialXpress are powerful easy-to-use software
packages to synthesize RF and high-speed serial data signals respectively
for a rbitrary waveform gen erators (AWG). It runs as an integral part of the
AWG7000 Series arbitrary waveform generators or from an external PC.
