SCPI Parameter Types
The SCPI language defines several data formats to be used in program messages and
response messages.
Numeric Parameters
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 such as MIN,MAX and DEF are also
accepted. You can also send engineering unit suffixes with numeric parameters (e.g., M, k,
m or u). If a command accepts only certain specific values, the instrument will
automatically round the input numeric parameters to the accepted values. The following
command requires a numeric parameter for the range value:
VOLTage:DC:RANGe {<range>|MIN|MAX|DEF}
Because the SCPI parser is case-insensitive, there is some confusion over the letter "M"
(or "m"). For your convenience, the instrument interprets "mV" (or "MV") as millivolts,
but "MHZ" (or "mhz") as megahertz. Likewise "MΩ" (or "mΩ") is interpreted as megΩ.
You can use the prefix "MA" for mega. For example, "MAV" is interpreted as megavolts.
Discrete Parameters
Discrete parameters are used to program settings that have a limited number of values
(like IMMediate, EXTernal or BUS). They have a short form and a long form just like
command keywords. You can mix upper- and lower-case letters. Query responses will
always return the short form in all upper-case letters. The following example requires
discrete parameters for the temperature units:
UNIT:TEMPerature{C|F|K}
Boolean Parameters
Boolean parameters represent a single binary condition that is either true or false. For a
false condition, the instrument will accept "OFF" or "0". For a true condition, the instrument
will accept "ON" or "1". When you query a Boolean setting, the instrument will always
return "0" or "1". The following example requires a Boolean parameter:
DISPlay:STATe {ON|1|OFF|0}
