Weiss Gallenkamp supply 14 ''Mini'' Test Chambers

The mini test chambers, offer an optimum solution with great test space volume, when only limited space is available.

Cambridge Silicon Radio have purchased 14 VTM 7004 ''Mini'' Test Chambers from Weiss Gallenkamp, and have recently placed another order for 14 of the same model.

CSR is the leading global provider of personal wireless technology and its product portfolio covers Bluetooth, FM receivers and Wi-Fi (IEEE802.11). CSR offers developed hardware/software solutions, based around its silicon platforms, that incorporate fully integrated radio, baseband and microcontroller elements. CSR''s customers include industry leaders such as Apple, Dell, LG, Motorola, NEC, Nokia, Panasonic, RIM, Samsung, Sharp, Sony, TomTom and Toshiba. The chambers will be used to test the latest in Bluetooth technology.

The mini test chambers, offer an optimum solution with great test space volume, when only limited space is available. Limited laboratory space and the necessity of installing testing systems directly at the workspace are factors demanding compact and silent running equipment. Temperature testing chambers of the mini-series fulfil these requirements. Temperature conditioning efficiency renders this compact and yet very quiet series of systems suitable for universal applications.

The major characteristics of this range are:

Optical conformity and the assignment of reliable materials and well-proven features For monitoring and controlling the test chamber is equipped with a powerful 32-bit control system M!NCON/32.

The terminal with LCD-display "MINCONTROL" offers input and display of values and states. IP54 certified switch cabinet Enhanced performance temperature fluctuations

Enhanced performance temperature changing rates

Extremely quiet
