ILLUMINATOR is the gold standard for portable RF test transmitters and signal generators. Wideband operation up to 6 GHz addresses all test transmitter needs even over unlicensed bands for LTE-U, LAA, and CBRS Band. Combined with ultra-portable handheld form factor and innovative touch interface for maximum ease of use, ILLUMINATOR serves laboratory and field applications including DAS and Small Cells radio planning and testing. Using modulated signals enables versatile applications vital to validate carrier configuration before deployment and avoid pilot pollution. Built-in optional wideband power amplifier extends capabilities for missions requiring high power CW test transmitter for oDAS test, design, and outdoor CW model calibration.
