Error messages

Invalid string data

The parser (syntax analysis program) expects a separator, but a character other than a

separator is sent. For example, although “;” should be used to separate two sent program

messages such as “MEAS IRIM;FMT LOGY”, the semicolon (;) for separating the program

messages is missing as “MEAS IRIM FMT LOGY”.

-151 Invalid string data

Character string data is expected but the given string data are invalid for some reason.

(Refer to IEEE488.2,7.7.5.2.) For example, the END message is received before the end

quotation mark character appears.

-131 Invalid suffix

The suffix does not meet the syntax defined in IEEE488.2,7.7.3.2 or is inappropriate for

the Agilent 4294A.

132 LIST SWEEP ONLY

When a sweep type other than the list sweep is specified, you attempt to execute a

command to specify all segments (entire sweep range) as the search range setting

(SEARNG FULL) or a command to specify a certain segment as the search target

(SEGMNUM <value>) and, as a result, the command is ignored. Before setting the search

range for the list sweep, specify the list sweep as the sweep type (command: SWPT LIST).

124 LIST TABLE EMPTY OR INSUFFICIENT TABLE

When the list sweep table is empty or insufficient, you attempt to select LIST as the sweep

type (command: SWPT LIST) and, as a result, the command is ignored. Before selecting the

list sweep as the sweep type, set the list sweep table correctly.

-250 MASS STORAGE ERROR

A mass storage error other than -257 occurs.

88 MATH FUNCTION NOT VALID FOR PERCENT FORMAT

When the percent format is selected as the display format, you attempt to change the

setting of data operations. In the percent format, data operations are fixed to delta %

(command: MATH DELP), and thus you cannot change the data operation setting to DATA

(command: MATH DATA), DATA-MEM (command: MATH DMNM), or DATA/MEM

(command: MATH DDVM).

105 MEASUREMENT PARAMETER NOT FOR ANALYSIS

When a measurement parameter other than |Z|-q is set, you attempt to execute a waveform

analysis command (for example, OUTPCERR?) and, as a result, the command is ignored.

Before executing a waveform analysis command, set the measurement parameter to |Z|-q

(command: MEAS IMPH).

-258 Media protected

You attempt to save/delete data to/from the storage device or initialize the media, but the

media is write-protected, and, as a result, the operation cannot be executed. This message is

displayed, for example, when you have specified the floppy disk drive as the storage device

1 2 ... 441 442 443 444 445 446 447 448 449 450 451 ... 468 469
