Specifications

Query Errors A query error indicates a problem has occurred in the instrument’s output
queue. When a query error occurs, it sets the Query Error bit (bit 2) in the
Standard Event Status Register. Query errors can be caused by the following:
• An attempt was made to read the instrument’s output queue when no
output was present or pending.
• Data in the instrument’s output queue has been lost for some reason.

Error Messages and Causes
Code Message Cause
–101 Invalid character Unrecognized character in specified parameter.
–102 Syntax error Command is missing a space or comma between parameters.
–103 Invalid separator Command parameter is separated by some character other
than a comma.
–104 Data type error The wrong data type (for example, number, character, string
expression) was used when specifying a parameter.
–108 Parameter not allowed Parameter specified in a command which does not require one.
–109 Missing parameter No parameter specified in the command in which a parameter
is required.
–113 Undefined header Command header was incorrectly specified.
–123 Numeric overflow A parameter specifies a value greater than the command allows.
–128 Numeric data not allowed A number was specified for a parameter when a letter is required.
–131 Invalid suffix Parameter suffix incorrectly specified
(e.g. .5SECOND rather than .5S or .5SEC).
–138 Suffix not allowed Parameter suffix is specified when one is not allowed.
–141 Invalid character data The discrete parameter specified is not allowed
(e.g. TRIG:SOUR INT - INT is not a choice).
–160 Block data error The block sent either contained more data then the Flash
ROMS could hold or the block count field disagreed with the
number of bytes actually sent.
–178 Expression data not allowed A parameter other than the channel list is enclosed in
parentheses.
–211 Trigger ignored Trigger occurred from a source other than the specified source.
–222 Data out of range The parameter value specified is too large or too small.
–224 Illegal parameter value The numeric value specified is not allowed.
–240 Hardware error Error was encountered while attempting to erase Flash ROMs
or Flash ROMs failed to respond correctly to the programming
sequence.
–252
Missing media No programmable ROM was found, or hardware malfunction.
–253 Corrupt media An incorrect checksum was read from the programmed
ROMs. This is indicative of a ROM hardware malfunction or a
data transmission error.
–258 Media protected A command was executed with the "RUN/LOAD" switch in the
"RUN" position when it should be in the "LOAD" position.
–310 System error If caused by *DMC, then macro memory is full.
