Willtek STABILOCK 4032
In excess of 5000 STABILOCK 4032 radio
test sets are currently in use worldwide.
This success has been due to the versatile
design, simple operation and wide variety
of system tests which can be made with
the “universal” test set.
Applications range from high-speed production tests and quality measurements
to servicing and commissioning tests. The
wide variety of hardware modules and
software options covering frequency
ranges up to 2.3 GHz, provide comprehensive capability of analog and digital
cellular, cordless and two-way radio
systems.
Additional capability includes base station
measurements and paging tests.
Systems include TETRA Digital Trunked
Radio, Tetrapol as well as CDMA base
station testing at 800 MHz and
1900 MHz. The GSM Option of the
STABILOCK 4032 now is also capable of
testing dual-band mobiles.
Please refer to individual data sheets for
further details of system performance.
Built-in spectrum analyzer
Detailed spectrum analysis from 2 MHz to
1 GHz (standard) or up to 2.3 GHz
(optional). Additional option for highspeed sweep and a host of useful
functions.
AUTORUN
Simple, BASIC-oriented programming
language for fully automated tests.
Ready-written programs are available for
all popular mobile telephone systems.
IEEE-488 interface
Fitted as standard. Ensures remote control
via controller or program downloads from
LAN servers.
High-speed measurements
Special firmware for final testing during
production cuts measuring times by
around 30%.
Reliability
All subassemblies are burnt-in tested,
with plug-in modules and SMD
technology.

Analzyer (Typical Performance)
Audio Generator and Analyzer (Typical Performance)
Typical performance is derived from the standard deviation of many hundreds of production
units operating under normal environmental conditions of 20°C.
Specifications below apply for the basic 4032 up to 999.99 MHz. When the FEX (Frequency Extension) option is fitted
please see *section at the end. Please refer to individual data sheets for performance of options.
