Used in setting the AGC amplifier gain.
Perform gain setting while monitoring the MIRR signal’s (peak) - (bottom) signal. The 37H command
can be used to output the value of a MIRR signal from the ATEST pin before A/D conversion. In
addition, in order to monitor amplitude stably, make adjustments by using the 34H command to
maximize the time constant.
Used in setting the RF amplifier output DC voltage.
Can be cancelled using DEQO in the 36H command.
