The radiating spherical dipole provides a reliable, electrically isolated, and -most importantly- repeatable and accurate signal test source for technical applications. The spherical dipole is comprised of two hemispheres, which form the radiation element of a spherical dipole antenna. Operation of the spherical dipole, and functional status, is provided through optical fiber interconnections back to the Control Unit. Both Spherical Dipoles available with the PSDS are interchangeable and operate with the same Control Unit. With the combination of two interchangeable spherical dipole antennas, the PSDS covers the frequency range of 100 kHz to 2.5 GHz. The SD-50 covers the frequency range of 100 kHz to 50 MHz, and the SD-2500 covers the frequency range of 10 MHz to 2.5 GHz.
