Antenna Measurement System AMS DAB

For testing the signal quality of car antennas under real life conditions, the mobile antenna measurement system AMS is a powerful and well-priced solution. With the DAB measurement box, it is possible to drive along the relevant reception area and to analyse problems afterwards.

Two antennas can be connected to only one measurement box simultaneously; when using two additional DAB tuners, up to four antennas can be connected. The DAB box records up to four measurement points per second. An external spectrum analyser can be connected to search for interfering signals or similar problems.

For simplified network configuration, the box includes a DHCP client. It is available with an internal or external GPS module. It is not necessary, but possible to connect a control computer while driving. If required, you can connect an external cockpit panel for remote control of the box on the road.

Options

Cockpit panel for monitoring and configuration
Connection to a spectrum analyzer
Live monitoring on PC or notebook
CAN Bus interface
