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.
Typical performance is derived from the standard deviation of many hundreds of production units operating under normal environmental conditions of 20°C.
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.
