CAUTION
• The maximum input level of the AUX Input connector
The maximum input level of the AUX Input connector is
+20 dBm. If a signal whose level exceeds the specified
value is input, the internal circuit of the MT8801C may be
damaged.
• AUX Output connector
The AUX Output connector is the dedicated output con-
nector of the signal generator in the MT8801C. If a trans-
mitter signal is input in the AUX Output connector, the in-
ternal circuit may be damaged.
