Test and Measurement
3G base station test system
Racal Instruments Wireless Solutions (RIWS) has announced its enhanced and upgraded 3G base station test system, the 6413A. It has been designed to help network operators test their networks prior to roll-out and to guarantee continued quality of service.
Traditional base station test systems focus on transmitter testing mainly because receiver testing is complex and difficult. The 6413A's lub control is a unique feature allowing network operators to carry out receiver and transmitter testing. Operators that conduct transmitter-only tests or just use a test mobile to make test calls risk failing to meet their expected quality of service.
The new 6413A is more compact for increased portability and is easier to use than its predecessor, the 6413, incorporating embedded touch-screen technology.
Data acquisition software
Acqiris offers a stand-alone multichannel acquisition software package, AcqirisMAQS. The package simplifies the monitoring and control of advanced data acquisition systems with multiple data channels and can be used for the remote operation of multiple acquisition systems at various locations.
With AcqirisMAQS any PC or laptop can be set up as a client to control multiple digitizer channels connected to an instrument server, a PC or processor that contains one or more Acqiris digitizer modules. Digitizer control is achieved via an Ethernet connection, simple crossover cable, or in any networked environment over the Ethernet. Client machines can have master control or combined master and monitoring rights on the server machine, allowing multiple clients to obtain data from the same digitizer systems simultaneously, while allowing one system-defined master client to change system parameters.
Pricing for AcqirisMAQS starts at $1990 for a master-only, single-user license. A free demo version of the software is available.
7 GHz probe
