IP plus (IP+) Feature:
This feature improves the receiver IMD (Intermodulation Distortion) by making the best use of the direct sampling architecture.
It optimizes the level of the ADC (Analogue/Digital Converter) for strong input signals in order to reduce distortion. It also minimizes the reduction in sensitivity for weak signals and improves IP3 (3rd order intercept point).

Push FUNCTION.
The FUNCTION window opens.
Touch IP+.
Every touch toggles the IP+ feature ON or OFF.
ON for better IP (linearity), OFF for better sensitivity.

Push EXIT to close the FUNCTION window.
The IC-7300 IP+ (Intercept Point Plus) feature activates on-chip Dither and Randomization in the ADC. IP+ has two selectable modes; ON (optimum linearity) and OFF (optimum sensitivity).
