Antenna Measurement System AMS Spektrum

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 spectrum measurement box, it is possible to drive along the relevant reception area and to search for reception inter-ferences and analyse problems afterwards.

The spectrum box records the measurement values of a connected spectrum analyser up to four times per second. If necessary, an EMC field probe can be connected, too.

For simplified network configuration, the box includes a DHCP client. The built-in GPS receiver supplies several data for the georeferencing. It is not necessary, but possible to connect a control computer while driving.

Options

Live monitoring on PC or notebook
CAN Bus interface
Connection to an EMC field probe

Recording and Analysis of the HF Spectrum

• Drive testing of car antennas

• Data recording of a connected spectrum analyser

• Standalone recording box without additional computer

• Georeferencing ot the measurement points: GPS status, speed, altitude etc.

• 4 measurement points per second

• Subsequent processing and editing of the measurement point list in an user-friendly analysis software

• Handling of large amounts of measurement data

• Connection to a number of web map services

Analysis Software Functions

• Live monitoring of the measured data

• Integration of streetmaps and satellite images that are available on the internet

• Consolidation of several measurement data sets

• Simultaneous representation of a number of measured variables as different dot sizes, colour gradient, shapes etc. or as bargraphs

• Time-distance plots with comparative function

• Multiple filter criteria to reduce the visualized data set

• Extraction of discrete frequencies from the recorded spectra

• Analysis settings can be stored in profiles for quick access

• Report generation, manually or automatically from templates: Spectra, measurement data diagrams, maps

• Statistical evaluation of the measurement data

•  Analysis of spectrum level differences

•  Computation of a 2D distribution function with interpolation
