Error number: -112
-112 Program mnemonic too long
The length of header is exceeding than 12 characters. The length of header would here
refer to the length of the series of characters that are separated with the use of columns (:).
Refer to IEEE488.2,7.6.4.1 for further details.
-113 Undefined header
Though the grammatical structure does not provide any problems, a command not defined
by E4991A has been received. For example, when a message; "DISP:TRAC1:X:AUTO"
has been sent toward the correct program message; "DISP:TRAC1:Y:AUTO", it will be
received by E4991A as an undefined command. Refer to the command reference and check
the correct commands.
-120 Numeric data error
Error that was caused by numeric data (including the numeric data other than 10 decimal
numbers) has occurred. From error numbers - 121 to - 121 unspecified numeric error has
occurred.
-121 Invalid character in number
There were invalid characters toward the received data and type. For example, within the
10 decimal numeric data, an alphabet is found, or within 8 decimal numeric data, 9 was
found.
-123 Exponent too large
Absolute figure of the exponent has exceeded to over 32,000. (Refer to IEEE488.2,
7.2.4.1)
-124 Too many digits
Mantissa’s number of digits in the 10 decimal numeric data element is exceeding over 255,
except the preceding 0. (Refer to IEEE488.27.7.2.4)
-128 Numeric data not allowed
On the position where E4991A would not receive numeric data element, the numeric data
element has been received. For example, when a message; "CALC1:FORM 3" has been
sent toward the correct program message; "CALC1:FORM RS", the numeric data element
will be received by E4991A as invalid. Refer to the command reference and check the
parameter that should be used for this command.
-131 Invalid suffix
Suffix (here meaning Unit) is not following the sentence structure defined by IEEE488.2,
7.7.3.2, or the suffix is not appropriate for E4991A. For example, when a message;
"SOUR:VOLT:STAR 10dbm" has been sent toward the correct program message;
"SOUR:VOLT:STAR 10mV", the suffix will be regarded by E4991A as invalid. Refer to
the command reference and check the unit that should be used for this command.
-134 Suffix too long
Suffix (here meaning Unit) display is written in over 12 characters. (Refer to IEEE488.2,
7.7.2.4)
-138 Suffix not allowed
After the numeric data in which the suffix (here meaning Unit) can not be inputted, the
suffix have been added. For example, when a message; "DISP:TRAC1:Y:PDIV 0.01rad"
has been sent toward the correct program message; "DISP:TRAC1:Y:PDIV 0.01", the
suffix will be regarded by E4991A as invalid. Refer to the command reference and check
