Measuring System 3100
Although every measurement test setup is different, and many times requires special solutions, GRANTE Corporation offers a standard setup for single polarized measurements, called MS 3100.
MS 3100 is equipped with four attenuator elements (two fixed and two variable attenuators) to achieve homogeneous frequency-dependent behaviour. Fixed attenuators (2×20 dB = 40 dB) protect the Rx modules of the ODUs from high power levels, while variable attenuators (2×(0…30) dB) – together with the fixed ones – model free-space attenuation and fading in the dynamic range of 40 to 100 dB (different dynamic range is available upon request).
Small attenuation values may be used for testing normal operation, while fading may also be simulated by increasing the overall attenuation of the fine-tunable variable attenuators.
The spectrum of the microwave link may be monitored via optional coaxial probes.
Besides testing single-ODU (1+0) link configurations, one may connect direct mounted hybrid combiners to the ODU interface to investigate (1+1) hot standby systems.
