-128 Numeric data not allowed
An numeric-value-data element (not violating the standard) has been received at a position
where this instrument does not accept one.
O
200 Option not installed
The command received has been ignored because of the mismatch between the contents of
an option for this instrument and the command.
For example, this error occurs when the source attenuator (power range) is set at a value
other than zero (SOUR:POW:ATT command) in a model not having the extended power
output option.
This error is not generated by front key operations.
-225 Out of memory
Insufficient memory is available in this instrument to perform the required operation.
P
-220 Parameter error
When a parameter-related error other than Errors -221 through -229 occurs, that error is
displayed.
-108 Parameter not allowed
The number of parameters exceeds that required for the command.
For instance, when a program message ":SENS1:SWE:TYPE LIN, SEGM" is sent instead
of a correct program message with a command ":SENS1:SWE:TYPE LIN" which requires
a parameter, the instrument receives the message as the number of parameters is invalid.
See the command reference to confirm the required number of parameters.
41 Peak not found
This error occurs when, after specifying a peak and executing the
CALC:MARK:FUNC:EXEC and CALC:FUNC:EXEC commands, the specified peak is
not found in the marker search analysis.
220 Phase lock loop unlocked
This error occurs when the PLL circuit of this instrument becomes unlocked while the
measurement is in progress. The measurement value is not correct. This error may occur
when an external reference out of specification is connected to this instrument. Should an
error occur with an external reference not connected, this instrument is faulty. Contact an
Agilent Technology sales office or the company from which you bought the instrument.
221 Port 1 receiver overload
The input to Test Port 1 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.
