<WHITE SPACE>
is ignored except in command identifiers. e.g. ‘
∗
C LS’ is not equivalent to ‘
∗
CLS’.
<WHITE SPACE>
is defined as character codes 00H to 20H inclusive with the exception of the NL
character (0AH).
The high bit of all characters is ignored.
The commands are case insensitive.
Command List
This section lists all commands and queries implemented in this instrument. The commands are
listed in alphabetical order within the function groups.
Note that there are no dependent parameters, coupled parameters, overlapping commands,
expression program data elements or compound command program headers; each command is
completely executed before the next command is started. All commands are sequential and the
operation complete message is generated immediately after execution in all cases.
The following nomenclature is used:
<rmt>
<RESPONSE MESSAGE TERMINATOR>
<nrf>
A number in any format. e.g. 12, 12.00, 1.2 e1 and 120 e-1 are all accepted as
the number 12. Any number, when received, is converted to the required
precision consistent with the use then rounded up to obtain the value of the
command.
<nr1>
A number with no fractional part, i.e. an integer.
The commands which begin with a
∗
are those specified by IEEE Std. 488.2 as Common
commands. All will function when used on the RS232 interface but some are of little use.
