Summary
SCPI Command Reference 5-6
Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com
The SCPI language defines several different data formats to be
used in program messages and response messages.
Commands that require numeric parameters will accept all
commonly used decimal representations of numbers including
optional signs, decimal points, and scientific notation. Special
values for numeric parameters like MINimum, MAXimum, and
DEFault are also accepted.
Engineering unit suffixes with numeric parameters (e.g., mV,
KV, mA, KHz) can also be sent. If only specific numeric values
are accepted, the function generator will ignore values which
are not accepted and will generate an error message. The
following command is an example of a command that uses a
numeric parameter:
SENSE:VOLT1:RANGE:UPPER 5.75
Discrete parameters are used to program settings that have a
limited number of values (e.g., trigger delay is applied to INPut
or OUTput or NONE).

mixed. Query responses always return the short form in all
upper case letters. The following command uses discrete
parameters:
:VXI:CONF:MON:DELAY:STATE {INPut|OUTput|NONE}
Boolean parameters represent a single binary condition that is
either true or false. The EMS accepts "OFF" or "0" for a false
condition. The EMS accepts "ON" or "1" for a true condition.
The instrument always returns
setting is queried. The following command uses a boolean
parameter:
:DISPLAY:TEXT:STATE { OFF | ON | 0 | 1 }
Table 5-1 summarizes the complete SCPI command tree
available to program the EMS. Refer to Section 4 in this
manual for more complete details on each command.
