The single portable box is produced by IZT and Enkom. They cooperate together for the digital broadcast coverage analysis. This device is able to analyze the UKW FM, HD Radio, DRM/DRM+, DAB/DAB+/DMB, ATSC, DVB-H/DVB-T, DVB-T2 and Tetrapol networks. The R3301 is used to connect with the receiver and RF recorder, and an Enkom measurement and and the analysis software suit which is named Permit.

Four receiver channels and an integrated GPS receiver which is for time and location reference is contained in the 30cm touch screen R3301. When it comes to the data-recording, an integrated server and four swappable hard drives are contained in it. They can separately offer more than 500Gbyte capacity by default. "This corresponds to more than six hours of continuous recording with up to 24Msample/s, which is sufficient for simultaneous recording of the complete range of FM stations or multiple DAB or DVB-T constellations," said IZT.



With an AC/DC power supply and short-term battery backup, the device is able to record, illustrate and analyse RF and quality parameters, including the spectrum, channel impulse response, single strength, constellation, modulation error ratio, bit error rate and radiation patterns.

The band occupancy is decided by the device automatically and the measurement results are displayed on a map interactively. " PerMIT is suited for coverage and mobile measurements," claimed IZT. "The range of options also includes connectable sensors for measuring position, direction, temperature, altitude, angle, displacement and user-specific results. In addition, measurement runs can be compared on the basis of stored measurement results."

IZT us a leader company in innovative, high-performance products for capturing, modifying and generating radio signals. ENKOM AG is a leading supplier which has the products and services relating to the planning and implementation of radio network infrastructure.
