(CALCulate:LIMit) and the second level from the third level (LIMit:FAIL?).
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 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 CALCulate, then CALC and
CALCULATE are both acceptable forms. Other forms of CALCulate, such as
CALCU or CALCUL will generate an error. Additionally, SCPI commands are case
insensitive. Therefore, you may use upper or lower case letters and commands of the
form CALCULATE, calculate, and CaLcUlAtE are all acceptable.
Implied commands are those which appear in square brackets ([ ]) in the command
syntax. (Note that the brackets are not part of the command; do not send them 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 partial
SENSe subsystem shown below:
[SENSe:]
VOLTage[:DC]:RANGe < range >|MIN|MAX
VOLTage[:DC]:RANGe? [MIN|MAX]
The root command SENSe is an implied command; so is the third level command
DC. For example, to set the digitizer's DC voltage range to MAX, you can send one
of the following three command statements:
SENS:VOLT:DC:RANG MAX
VOLT:DC:RANG MAX
VOLT:RANG MAX
