68 Agilent E8462A Relay Multiplexer Command Reference
Note There is a space between the second level command (for example, CLOSe) and the
<channel_list>.
Command
Separator
A colon (:) always separates one command from the next lower level command as
shown below:
ROUTe:SCAN:MODE?
Colons separate the root command from the second level command
(
[ROUTe:]SCAN), and the second level from the third level (SCAN:MODE?).
Abbreviated
Commands
The command syntax shows most commands as a mixture of upper and lower case
letters. The upper case letters indicate the abbreviated spelling for the command.
For shorter program lines, send only the abbreviated form. For better program
readability, you may send the entire command. The instrument will accept either the
abbreviated form or the entire command.
For example, if the command syntax shows
DIAGnostic, then DIAG and
DIAGNOSTIC are both acceptable forms. Other forms of DIAGnostic, such as
DIAGN or DIAGNOS will generate an error. You may use upper or lower case letters.
Therefore,
DIAGNOSTIC, diagnostic, and DiAgNoStIc are all acceptable.
Implied
Commands
Implied commands are those which appear in square brackets ([ ]) in the command
syntax. (Note that the brackets are not part of the command and are not sent to the
instrument.) Suppose you send a second level command but do not send the
preceding implied command. In this case, the instrument assumes you intend to use
the implied command and it responds as if you had sent it. Examine the portion of
the
[ROUTe:] subsystem shown below:
[ROUTe:]
CLOSe? <channel_list>
The root command [ROUTe:] is an implied command. To make a query about a
channel's present status, you can send either of the following command statements:
ROUT:CLOSe? <channel_list> or CLOSe? <channel_list>
Common
Command Format
The IEEE 488.2 standard defines the Common commands that perform functions
like reset, self-test, status byte query, etc. Common commands are four or five
characters in length, always begin with the asterisk character (*), and may include
one or more parameters. The command keyword is separated from the first
parameter by a space character. Some examples of common commands are shown
below:
*RST *ESR 32 *STB?
Linking
Commands
Linking IEEE 488.2 Common Commands with SCPI Commands. Use only a
semicolon between the commands. For example:
*RST;OUTP:TTLT4 ON or ARM:COUNt 25;*WAI
