For example, :LISTout[:STATe] {0|1|OFF|ON}
Integer
Unless otherwise specified, the parameter can take any valid integer value.
Note: Do not set decimal as parameter, otherwise it may occur error.
Real
Unless otherwise specified, the parameter can take any valid integer value.
Discrete
Parameter can only take some specified numbers or characters.
For example, the parameter in the command :SOURce:Mode {NORMal|SER|PARA} can only be NORMal, SER
o r PARA.
ASCII String
String parameter contain all ASCII string sets. Strings must begin and end with paired quotes; it can use single
or double quotation marks. The quotation and delimiter can also be part of a string by typing it twice and not
adding any characters.
For example, set IP: SYST:COMM:LAN:IPAD "192.168.1.10"
Shorthand Rule
All commands are case sensitivity. If command writes in abbreviation format, all capital letters in the command
should input completely.
Data Return
Data return is divided into single data and batch data. The single data return is the corresponding parameter type, in
which the real return type is express in scientific notation. The part before e retains three figure behind the decimal
point, and the e part retains three figure; the batch return must be obey IEEE 488.2# string data format, ‘#’+ the
length of character bits [fixed to one character] + ASCII valid value+ valid data+ end mark [‘\n’]
For example, #3123xxxxxxxxxxxxxxxxxxx\n represents 123 strings batch data return format, ‘3’ presents “123”
occupies three character bits.
Note: If return data is invalid data, use * to represent it.
