Missing parameter
M
-109 Missing parameter
The number of parameters is less than that required for the command, or the parameter has
not been entered. For example, the command SENS{1-6}:SWE:POIN requires one more
parameter.
Therefore, when a message "SENS1:SWE:POIN" is sent to a correct program message
"SENS1:SWE:POIN 201" this instrument receives the former message as an invalid one
because all parameters have not been entered. Enter command parameters correctly.
N
70 No GPIB system controller
The GPIB system controller is not set properly.
This error occurs when USB/GPIB interface is not connected or the interface setting is
improper, during the measurement for power calibration data or for that in scalar-mixer
calibration.
It also occurs when USB/GPIB interface is not connected or the interface setting is
improper, though the control of the external signal source is enabled.
Ensure the connection of USB/GPIB interface and its setting.
52 No valid memory trace
This error occurs when you have executed either DISP:WIND:TRAC:MEM ON command
to display memory trace, or any other command to enable data caqlculation using memory
trace (CALC:MATH:FUNC command with other than NORM is specified), though no
valid data exists in memory trace.This error is not generated by front key operations.
-120 Numeric data error
An error resulting from the numeric value data (including numeric value data having no
decimal point representation) has occurred. A numeric value error other than Errors -121
through -129 has occurred.
-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.
It also occurs when you try to enable the time domain function in a model not having the
time domain option.This holds true for the frequency offset option.
This error is not generated by front key operations.
