Error Messages
• For dual channel power meters: if the master is changed to IMM, BUS or
HOLD, error –221 “Settings Conflict” occurs. In such situations the
slave’s TRIG:SOUR must be changed so that it is no longer a slave.
• For dual channel power meters: setting the trigger source to INT1,
INT2 or EXT when the trigger source of adjacent channel is INT1, INT2 or
EXT in different mode (NORMal or AVERage), error –221 “Settings
Conflict” occurs.
• For dual channel power meters: if only a channel is connected with
P- Series power sensor, sensor mode is AVERage and trigger source is
EXT, setting the trigger source of adjacent channel to INT1, INT2 or
EXT, error –221 “Settings Conflict” occurs.
• If the source is changed to INT1, INT2 or EXT and SENS:SPEED has a
value of 200, error –221 “Settings Conflict” occurs.
• If the source is changed to INT1, INT2 or EXT and SENS:DET:FUNC is
set to AVERage, error –221 “Settings Conflict” occurs.
• If the source is set to INT1 or INT2 when connecting the N1920 sensor
in average mode, error –221 “Settings Conflict” occurs.
