Antenna Measurement System AMS DVB-T

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 DVB-T measurement box,  it is possible to drive along the relevant reception area and to analyse problems afterwards.

Four antennas can be connected to only one measurement box simultaneously. The DVB-T box records up to four measurement points per second. An external spectrum analyzer 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.

Options

Connection to a spectrum analyzer
Live monitoring on PC or notebook
CAN Bus interface

Measurement, Recording and Analysis of the Signal Quality

• Drive Testing of car antennas

• Standalone measurement box without additional computer

• Up to four DVB-T antennas simultaneously

• Well-priced solution for antenna tests under real-life conditions

• Recording of SNR, MER, BER, carrier-offset, AGC

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

• 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

• Computation of a 2D distribution function with interpolation

• Analysis of the energy integral
