P- Series power sensor is connected the error –241, “Hardware missing”
occurs.
If the calibration was not carried out successfully the error –231, “Data
Questionable; CAL ERROR” occurs. If you are using an N1912A the
error message specifies which channel failed calibration.
If there is no sensor connected, the error –241, “Hardware Missing”

If this command is set to ON and TRIGger[SEQuence[1]|2]:COUNt
is set to a value >1, the error –221, “Setting conflict” occurs.
If this command is set to ON (for dual channel, at either measurement
channel) when a P- Series power sensor is connected (for dual channel,
at either measurement channel) and is in the wait- for- trigger state for
external trigger buffering, the error –224, “Illegal parameter value”
occurs.
