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 Options 313, 314, 413, and 414 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 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.
224 Port 4 receiver overload (For Options 413 and 414 only)
The input to Test Port 4 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.
73 Power meter not settled
The measurement value of the power meter is unstable, or it goes outside the tolerance.
This error occurs when the power meter's measurement value does not become stable
within about 10 seconds during measurement for power calibration data or that for
scalar-mixer calibration data.
This error also occurs when the power calibration value exceeds the set tolerance.
In addition, it occurs when the power meter fails to respond for any reason, such as
power-down for example, during measurement under the same conditions.
Ensure a firm connection of the power sensor.
241 Power on test failed
This error occurs when the power-on test fails, indicating a failure of this instrument.
Contact an Agilent Technology sales office or the company from which you bought the
instrument.
61 Power unleveled
The out power level exceeds available range.
For example, if the level after correction exceeds the power level that can be outputted
when correcting the power level with the power calibration and power slope feature, this
error occurs.
Check that the power level is set correctly, the power calibration has been performed
correctly and the correction value of the power slope is set correctly.
