After input signal
from SSG, press
[

adjustment value.
[PC test mode]
After input signal
from SSG, press
[Apply] button to
store the
adjustment value.
Adjust with the
analog signal.
*8: Because “RSSI at -80dBm adjust” of NXDN Narrow is adjusted by adjusting “RSSI at -80dBm adjust [Analog Narrow]”, it is not necessary to adjust
“RSSI at -80dBm adjust” of NXDN Narrow.
