Port 2 receiver overload
NOTE When FOM function or an external signal source is used over 8.5 GHz frequency
measurements with E5071C-Over 8.5 GHz Options, there is a possibility that overload
detection and power trip occurs even if you measure the devices under the maximum input
level. In that case, turn OFF the overload & power trip detect function after ensuring the
value of input power level.
222 Port 2 receiver overload
The input to Test Port 2 exceeds the maximum input level. The measurement value is not
correct. When a DUT is an amplifier or the like, this error may occur, damaging the
receiver in the worst case. Should this error occur with a passive part used as the DUT or
with nothing connected to the test port, this instrument is faulty. Contact an Agilent
Technology sales office or the company from which you bought the instrument.
If this error occurs, the stimulus signal output is automatically turned to off.

223 Port 3 receiver overload (for 4 Port Option only)
The input to Test Port 3 exceeds the maximum input level. The measurement value is not
correct. When a DUT is an amplifier or the like, this error may occur, damaging the
receiver in the worst case. Should this error occur with a passive part used as the DUT or
