SCPI Command Basics 5-24
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.
TRIG:DELAY 0.035
When a real, non-integer value is returned in a reply from the
1256, the floating point notation will be used. The only non-integer
values
returned
TRIGGER:DELAY and the OUTPUT:DELAY. The values will be a
number between 0.0 and 10.0. At most, 6 digits follow the decimal
point.
Integer values may be sent in the command using decimal, octal,
hexadecimal, or binary values. The default base for values is
decimal.
To specify a hexadecimal value, use the prefix #H. To specify an
octal value, use the prefix "#Q". To specify a binary value, use the
prefix "#B". The following values are all equivalent.
123
#B1111011
#H7B
#Q173
When an integer value is returned In a reply from the 1256, the
value will be a decimal number.
Discrete parameters are used to program settings that have a
limited number of values. Parameters are NOT case sensitive. As
an example of the discrete parameter, the TRIGGER:SOURCE
command is specified as:
:TRIGger
:SOURce
Meaning the parameter must be one of the following:
BUS
HOLD
IMM
IMMEDIATE
EXT
Note that, just like command keywords, discrete parameters may

1256
123 decimal
1111011 binary = 123 decimal
7B hex = 123 decimal
173 octal = 123 decimal
{ BUS | HOLD | IMMediate | EXT }
