Despite its compact external dimensions, the CR 4000 has two seperate antennas for VHF and SHF emissions. A switch on the front of the unit can be used to switch between the two frequencies. The transmission power of the calibrator is freely scalable in 5 db-steps from -85 dBm up to -40 dBm. If the battery capacity is no longer sufficient, the CR 4000 can also be operated via an external power supply with a standard USB cable.
