Command Separator A colon (:) always separates one command from the next lower level command as shown below:
ROUTe:SCAN:MODE VOLT
Colons separate the root command from the
(ROUTe:SCAN) and the
Abbreviated The command syntax shows most commands as a mixture of upper and Commands lower case letters. The upper case letters indicate the abbreviated spelling
for the command. For shorter program lines, send 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 MEASure, then MEAS and MEASURE are both acceptable forms. Other forms of MEASure, such as MEASU or MEASUR will generate an error. You may use upper or lower case letters. Therefore, MEASURE, measure, and MeAsUrE are all acceptable.
Command keywords can be entered in their full form, as shown above, or can be entered in their short form. In this manual, the entry required in short form commands is always capitalized. The short form is generally used for examples in this manual.
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 this excerpt from the [ROUTe:] subsystem shown below:
[ROUTe:]
SCAN <channel_list> :MODE <mode> :MODE?
:PORT <port>
Both the root command [ROUTe:] is an implied command. To set the instrument’s scanning list, you can send either of the following command statements:
ROUTe:SCAN (@100:115) | or SCAN (@100:115) |
Note You must include a space between the keywords and any parameters.
