Invalid string data
F. Messages
The parser (a syntactic analysis program) had been expecting a delimiter, but a character
that is not a delimiter has been sent.
-151 Invalid string data
Character string data has been expected, but the character string data that appears is invalid
for some reason (see 7.7.5.2, IEEE488.2). The END message is received before the ending
quotation mark character appears, for example.
-131 Invalid suffix
The suffix does not comply with the syntax defined in 7.7.3.2, IEEE488.2. Or it does not
suit 4294A.
L
53 Log sweep requires 2 octave minimum span
The span of sweep range is not satisfied the requirement for logarithmic sweep. The sweep
type is automatically changed to linear sweep when this error occurs.
For example, this error occurs when, with the start and stop frequency are set 1 MHz and 2
MHz respectively, the sweep type is changed to logarithmic sweep.
Set the stop frequency to more than four times as many as the start frequency. And then
select logarithmic sweep.
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.
75 Multiport test set not enabled
This error occurs when multiport test set calibration is performed while test set control is
not enabled.
N
56 Not enough points for connector model
This error occurs when the connector measurement function of the SRL measurement is
performed with the number of measurement points less than 101. Use at least 101 points.
52 No valid memory trace
This error occurs when there is no valid memory trace data and :DISP:
WIND:TRAC:MEM ON or DISP:WIND:TRAC:STAT ON is received or parameters other
than “NORM” is set with CALC:MATH:FUNC.
-120 Numeric data error
