This adjustment is performed in order to adjust the transmission
distance of RF signal for DIAT communication.
Connection:

1. Connect the oscilloscope to TP815 (RF AMP OUT) and GND

on the DIAT TRANSMITTER board.

2. Connect DIR-T1 to  DIR-T1  jack (J910).
3. Confirm trigger is locked.
4. Adjust RV801 on the DIAT TRANSMITTER board so that

the center of waveform becomes 2.2 to 2.4 Vp-p.

VOLT/DIV : 500 mV
TIME/DIV : 500 ns

level : 2.2 to 2.4 Vp-p
