Error messages
FREQUENCY SWEEP ONLY
When a measurement parameter other than COMPLEX Z-Y (i.e., scalar parameter
measurement) is selected, you attempt to select a display format not available for the
measurement parameter, for example, the complex plane display format (command: FMT
COMP), and, as a result, the command is ignored. When a measurement parameter other
than COMPLEX Z-Y is selected, select a display format from the linear scale format
(command: FMT LINY), the log scale format (command: FMT LOGY), or the percent
format (command: FMT PERC).
131 FREQUENCY SWEEP ONLY
When a sweep parameter other than frequency is specified, you attempt to execute an
equivalent circuit analysis command (CALECPARA and so on). You can execute the
equivalent circuit analysis only when the sweep parameter is frequency.
-105 GET not allowed
A group execution trigger (GET) was received in a program message. (Refer to
IEEE488.2,7.7.)
-240 Hardware error
The program command cannot be executed due to a hardware-related error. This indicates
that an error other than -241 to -249 has occurred.
-241 Hardware missing
The received command or Query complies with the standard but cannot be executed due to
hardware-related reasons (for example, the option is not installed).
-111 Header separator error
The header separator is wrong. This error is displayed when a character other than a
defined header follows the header. For example, when "*SRE 4" is correct, a character
follows the header without a space as "*SRE4".
-114 Headers Suffix out of range
The suffix of the header is out of range. The suffix of a numeral parameter that follows the
SCPI command makes the header invalid.
-224 Illegal parameter value
The value of the parameter is illegal.
-282 Illegal program name
The program name is illegal. This message is displayed, for example, when you attempt to
delete a program name that does not exist, define an existing program name again, or refer
to a program that does not exist.
-283 Illegal variable name
