Measurement options:

PSV antennas or loads: from 25 MHz do 18 GHz
Noise number: 10 MHz to 26,4 GHz; from 1,6 GHz above only through its own TRX as an intermediate frequency, directly 10 MHz to 1,6 GHz
Performance: do 26GHz, max. the load on individual frequencies will be specified by those interested in measurements
do 26GHz, max. the load on individual frequencies will be specified by those interested in the measurement.

Available measurements 10 GHz 100W WR90 a WR75 a 24 GHz 100W WR42

Measurements are also possible at frequency 47 GHz do 10 W and using a WR22 waveguide. In the case of interest. It must be specified in the request.

Spectrum analyzer: do 26 GHz – 47 GHz on special request
Used device outputs: Connectors N, SMA , 7/16 and R100 waveguides, R120 a R220, ( WR75, WR90, WR42, WR22) in the case of other device terminations, the measurement participant will provide the appropriate reductions.
