Tescom TC-3000A
Bluetooth Tester
TESCOM
TC-3000A Bluetooth Tester eliminates the need
for several costly testers by combining key
RF and Protocol test & measurement functions
in one convenient box. Designed for a wide range
of applications in R&D, manufacturing, QA
and service, this feature-packed powerful instrument
is simple to use, lightweight and portable,
and may be operated with all standard AC voltages.
In addition to Bluetooth testing applications,
TC-3000A may be used for non-Bluetooth RF testing
along the 2.4GHz ISM band.
System
Architecture:
TC-3000A is made up of two main blocks, a RF/DSP
module and a host CPU module, and is connected
by a host controller interface (HCI) that is
identical to Bluetooth system architecture.
The RF/DSP module provides an RF interface to
DUT, performs physical measurements and manages
the Bluetooth link. The internal host CPU (PC),
which runs on a Linux platform, takes care of
user interface (UI) functions including display,
key input and I/O controls for RS-232C, USB,
PCMCIA, LAN and other standard peripheral devices.
The adoption of an open OS minimizes unnecessary
constraints on system optimization. This simple,
elegant system architecture takes advantage
of both the power of DSP and the convenience
of a PC.
Custom Protocol Stack:
The TC-3000A Bluetooth protocol stack has been
developed with in-house technology in order
to gain total control of the performance and
feature set of the tester. Its unique protocol
stack architecture positions ¡®queues¡¯
between protocol layers, making it conceptually
simple and easy to apply. This approach helps
guarantee the system¡¯s long-term
supportability, while efficiently handling future
customization and enhancement requirements.
Versatility of TC-3000A:
TC-3000A can interface with DUT through
most known HCI interfaces. Additionally, the
RF/DSP module can relinquish control to an external
PC through standard HCI, allowing for an emulated
Bluetooth development environment. Remote connection
through TCP/IP allows the efficient control
of multiple testers from a PC located practically
anywhere in the world.
Speed test mode:
It is essential to minimize the test
time in manufacturing. TC-3000A is capable of
skipping the time-consuming INQUIRY procedure
by reading the Bluetooth device (BD) address
directly through HCI. Test configurations can
be edited to reduce the number and time of tests.

Bluetooth
Test Platform
TC-3000A combined with a TESCOM
quality test fixture provides predictable RF
coupling and shielding performance, to offer
an economical, quality Bluetooth test platform
for production, service or R&D environments.
Since most Bluetooth devices
use sealed antenna due to their size, final
RF tests must be done over the air (OTA). In
case of module or PCB testing, contact probes
may also be used. In either case, testing must
be completed under an adequately RF isolated
condition with reliable RF coupling. A simple
isolation box that disregards internal resonance
and shielding qualification will result in unreliable
RF test data. All TESCOM isolation boxes are
designed to minimize this problem. In practice,
OTA coupling over a wide frequency band exhibits
some level of frequency slope due to antenna
bandwidth or cable connector reflections. This
channel-dependent residual slope may need calibration
to guarantee the accuracy of TX power measurement.
TEM Cell TC-5060A/B
TEM Cell is a broadband radiation test cell
that provides both high isolation and predictable
RF coupling. The total coupling loss through
typical DUT antenna to TEM Cell output is around
30dB at Bluetooth frequencies. With the additional
filtered data port and power lines, the desktop-size
TC-5060A/B offers an ideal radiation test platform
for small RF devices, such as Bluetooth devices.
Shield Box
TESCOM's popular absorber-lined Shield Boxes
are widely used for RF test fixtures in R&D,
service or manufacturing worldwide. These manual
or pneumatic boxes with device fixtures can
handle many different types of devices, such
as PC assemblies, RF modules or final products.
Various RF signal connection methods, such as
probe heads, OTA couplers or special connectors,
can also be supplied by TESCOM. Most units also
include the pneumatic operation option, which
relieves operator fatigue in manufacturing.
High isolation and the absence of in-band resonance
in every TESCOM boxes improve test repeatability.
