IP Plus function
The IP Plus function improves the Intermodulation
Distortion (IMD) quality by optimizing the direct
sampling system performance.
This function optimizes the Analog/Digital Converter
(ADC) against distortion when you receive a strong
input signal. It also improves the Third-order Intercept
Point (IP3) while minimizing the reduction of the
receiver sensitivity.
Touch [IP+] on the side menu to turn the IP Plus
function ON or OFF.
ON: Prioritizes the IP quality.
OFF: Prioritizes the receive sensitivity.
