Coverage Mapping

There is a growing demand for low cost

coverage mapping solutions. Anritsu’s

Coverage Mapping measurements option

provides wireless service providers, public

safety users, land mobile radio operators,

and government officials with indoor and

outdoor mapping capabilities.

Outdoor Mapping

With a GPS antenna connected to the

instrument and a valid GPS signal, the

instrument monitors RSSI and ACPR levels

automatically. Using a map created with

Map Master, the instrument displays maps,

the location of the measurement, and a

special color code for the power level.

The refresh rate can be set up in time

(1 sec, minimum) or distance. The overall

amplitude accuracy coupled with the GPS

update rate ensures accurate and reliable

mapping results.

Indoor Mapping

When there is no GPS signal valid, the

Spectrum Master uses a start-walk-stop

approach to record RSSI and ACPR levels.

You can set the update rate, start location,

and end location and the interpolated

points will be displayed on the map.

Export KML Files

Save files as KML or JPEG. Open KML files

with Google Earth™. When opening up

a pin in Google Earth, center frequency,

detection method, measurement type, and

RBW are shown on screen.

Map Master™

The Map Master program creates

maps on your PC compatible with the

Spectrum Master. Maps are created by

typing in the address or by converting

existing JPEG, TIFF, BMP, GIF, and PNG

files to MAP files. Utilizing the built-in

zoom in and zoom out features, it is easy

to create maps of the desired location on

your PC and transfer to the instrument

with a USB flash drive. Map Master also

includes a GPS editor for inputting latitude

and longitude information of maps from

different formats.
