The SRM basic unit is fitted with a multi-pole socket in addition to the standard N connector. What is this used for?
The multi-pole antenna plug that is provided in addition to the N connector contains, among other things, an EEPROM in which the antenna data_antenna type, correction values as determined by calibration_are stored. The same is true of the hybrid coaxial extension cables supplied by Narda STS which have the calibration data stored in the multi-pole plug. When you plug this into the corresponding socket on the SRM, the device automatically detects the antenna or cable and takes the correction values into account in the result. The multi-pole antenna plug also performs the switching operations for triaxial antennas.
