Antenna Diversity Measurement System (ADMS)

The Antenna Diversity Measurement System (ADMS) is a high-capacity multi-channel L-band or IF signal recording system.  It is particularly suitable for extended recording campaigns in a mobile environment, as in the Antenna Diversity Measurement Project.
