The production solution based on the ¸SMU200A

The new standard in production

Based on the successful ¸SMU200A
platform, the ¸SMATE200A is spe­cifi cally designed for production envi­ronments. As such, the display and front
panel user interface have been removed,
the connectors moved to the rear, and
performance has been optimized for
fastest setting times to improve factory
throughput. Like the ¸SMU200A,
however, the two-generators-in-one
concept has been kept, occupying four
height units – a plus for production
where space is at a premium. All of this
is available without compromising the

excellent RF performance and base­band fl exibility synonymous with the
¸SMU200A.

Speaking of fl exibility, the modular design
concept of the ¸SMATE200A means
that the ¸SMATE200A can easily be
adapted to the needs of any application.
Users have the choice of either 3 GHz or
6 GHz RF outputs in one or two paths and
may opt for up to two completely inde­pendent baseband sources. As in the
¸SMU200A, these sources may be
used to produce complex signals in real-

time or output preloaded waveforms from
the internal arbitrary waveform generator.

In addition to its inherent speed, the
¸SMATE200A also offers a special
function to permit fast switching between
different test signals. The multisegment
waveform function allows users to eas­ily combine waveforms, such as GSM and
WCDMA, during test setup for even faster
tests in production. This is just one of the
¸SMATE200A’s numerous adapta­tions to the special requirements of the
production environment.

Vector Signal Generator ¸SMATE200A 3

Designed for production

Designed for speed, the ¸SMATE200A
is ideal for production lines where time is
critical. In remote control operation via the
IEC/IEEE bus, setting times are <2 ms and
even faster in List mode (<400 µs) where
predetermined changes in frequency and
level outputs may be specifi ed in advance.
New with the ¸SMATE200A, the Fast
Hop mode improves List mode capabil­ity by allowing users to arbitrarily address
up to 10 000 frequency/level pairs in any
sequence via a serial bus, maximizing fl ex­ibility for test engineers. To further reduce
test times, special hardware triggers are
also added, allowing control of frequently
used functions, including RF ON/OFF
and MODULATION ON/OFF. All of these
enhancements are designed to reduce the
total cost of ownership in production envi­ronments.

Setting time after a change in frequency

Instrument size and connectivity are also
crucial elements in production. After all,
lower space requirements mean lower
costs – particularly in a clean-room envi­ronment. Owing to its two-path concept,
the ¸SMATE200A occupies as little
as 50 % of the space required by a sin­gle-channel instrument. To allow easy
rack installation, the ¸SMATE200A is
equipped with rear connectors as stan­dard.

Since production conditions require
robust instruments, the ¸SMATE200A
is designed for longer life. Its wear-free,
electronic attenuator signifi cantly length­ens product life over those instruments
employing mechanical attenuators. Other
measures affording longer life include
an optimized cooling system to keep the
instrument’s internal temperatures as
low as possible even when installed in a
rack with elevated ambient temperature.
Lower temperatures reduce component
stress, thus increasing their lifespan.

4 Vector Signal Generator ¸SMATE200A

In production, one problem facing test

gg

engineers is the tradeoff between test
time and the need to stimulate each
DUT with varying, complex signals. The
¸SMATE200A has the answer: the
multisegment waveform function. This
feature allows users to combine up to
100 waveforms stored simultaneously
in memory, making it possible to switch
between waveforms without fi rst hav­ing to load each one separately. This not
only saves time during setup, but more
importantly reduces the time for switch­ing between waveforms to around 5 µs.
Users even have the option to specify
seamless linking of waveforms to ensure
phase stability – for example, during
receiver tests where resynchronization
can now be avoided.

Another time-saving feature for test
engineers, the Remote Desktop Con­nection of Microsoft’s Windows XP ope­rating system, may be used via Giga­bit LAN interface to check and mod­ify test software as needed with­out having to be physically in front

of the ¸SMATE200A. Of course,
users on site may also access the
¸SMATE200A user interface by
means of the VGA output and a USB
mouse and keyboard, same as for the
¸SMU200A.

Just because the ¸SMATE200A is
designed for speed doesn’t mean it lacks
in performance. The ¸SMATE200A
ships standard with the same excellent
RF characteristics as the ¸SMU200A,
typically –135 dBc/Hz for a 1 GHz car­rier at 20 kHz offset. In addition, users
may opt for the low phase noise option to
achieve even higher phase noise suppres­sion, typically 5 dBc/Hz improvement. The
superior combination of speed and signal
quality makes the ¸SMATE200A the
ideal LO substitute.

This low phase noise performance cou­pled with the highly linear I/Q modulator
lends itself to the ¸SMATE200A‘s
excellent ACLR and EVM measurement
capability. Both parameters are espe­cially important to power amplifi er man­ufacturers – even more so with imple­mentation of advanced, complex mod­ulation schemes. It is also worth men­tioning that excellent ACLR and EVM
characteristics may be achieved simul­taneously using the same test signal.
Again, the advantage is greater mea­surement speed.

Like the ¸SMU200A, the
¸SMATE200A offers internal base­band generation of signals with up to

requisite for generating signals with
good modulation characteristics such as
EVM, and the ¸SMATE200A makes
no compromises. For RF bandwidth
requirements up to 200 MHz, users may
input analog I/Q signals to each RF path
independently. The ¸SMATE200A
offers all of this plus the same high spu­rious suppression that has come to be
known in the ¸SMU200A.

¸SMATE200A not only offers two
independent RF sources, but also up to
two independent baseband generators
whose signals can be digitally added
internally. The result is a single instru­ment containing two units specifi cally
designed to work together. This elimi­nates the need for external cabling, mak­ing setup both simple and compact.

In production, it is not uncommon to
have many lossy elements between
the signal generator and the DUT.
To compensate, the generator must
have suffi cient output power. The
¸SMATE200A with its high-power
output option provides levels of typically
+26 dBm. Opting for the high-power out­put option does not involve replacing the
electronic attenuator. It is thus able to
conserve the wide output level range.

The high-precision level control of the
¸SMATE200A is based on a tem­perature-controlled RMS detector. This
not only translates to high precision,
but also to high level repeatability, typ­ically around 0.05 dB. This characteris­tic is especially important in production,
because it allows the exact same test
conditions to be established repeatedly
over a long period of time.

Connectivity

Versatile connectivity of the
¸SMATE200A combines classic
RF BNC outputs with additional inputs
and outputs through SCSI connectors.
These connectors further simplify and
speed up installation during setup.

An external keyboard and a mouse or
memory stick can be connected via USB
interfaces on the rear panel. Likewise, a
VGA output is available for connecting
an external display.

The ¸SMATE200A can be remote­controlled via GPIB or LAN inter­faces. With the introduction of the
¸SMATE200A, the capability to util­ize a Gigabit Ethernet is offered, yielding
shorter test times during production.

Modular design

Owing to its modular design, the
¸SMATE200A may be adapted
to virtually any requirement. As users
require new functionality, the appropri­ate options may be added later.

Low total cost of ownership is more than
just a motto with the ¸SMATE200A
– it applies to every aspect of the instru­ment, including its three-year calibration
cycle. This translates to signifi cant cost
savings and reduces system down time.
