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 Keysight Technologies sales office or the
company from which you bought the instrument.
If this error occurs, the stimulus signal output is automatically turned to off.
When FOM function or an external signal source is used over 8.5 GHz
frequency measurements, 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.
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 with nothing connected to the test port, this
instrument is faulty. Contact an Keysight Technologies sales office or the
