NL The new line character (0AH)
NL^END The new line character with the END message
^END The END message with the last character of the message
Responses from the instrument to the controller are sent as
<RESPONSE MESSAGES>.
A
<RESPONSE MESSAGE> consists of one <RESPONSE MESSAGE UNIT>
followed by a <RESPONSE MESSAGE TERMINATOR>.
A
<RESPONSE MESSAGE TERMINATOR> is the new line character with the END
message NL^END.
Each query produces a specific
<RESPONSE MESSAGE> which is listed along with
the command in the remote commands list.
<WHITE SPACE> is ignored except in command identifiers (thus, for example,
*
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 not case-sensitive.
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>
<cpd> <CHARACTER PROGRAM DATA>: a short mnemonic or string such as
ON or OFF.
<nrf> A number in any format. For example, 12, 12.00, 1.2e1 and 120e-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.
[…] Any item(s) enclosed in these square brackets are optional parameters. If
they enclose more than one item then all or none of the items are required.
The commands which begin with an asterisk (
*
) are those specified by IEEE Std. 488.2
as Common Commands. All will function when used on the RS232 interface but some
have little applicability here.
Channel Selection
Most commands act on a particular channel of the generator. The following command is
used to select the required channel. Subsequent commands will change only the specified
parameter on the selected channel.
