As an option a switch box is provided to the High Frequency antennas (Fig.

12.8). With this switch box it is possible to measure with only the receiver in

one HF antenna and only the transmitter in the other HF antenna. This

enables different types of tomographic measurements and velocity analysis

as CMP (Common Mid Point). The data cables from the two antennas are

connected to the switch box and the switch box to the CX Main unit.
