Command Names
Generally all commands of greater than four characters have an alternate abbreviated form
using only the upper case letters and number (if used).
Upper or lower case characters may be used for all commands.
For example, to set the amplitude of RF Generator 1, you could use any of the following
commands:
RFGENERATOR:AMPLITUDE1 -10DBM or
RFGenerator:AMPLitude1 -10DBM
rfgenerator:amplitude1 -10DBM or
rfg:ampl1 -10DBM or
RFG:AMPL1 -10DBM
Programming Format Conventions
Syntax commands and returned data descriptions use the following format conventions.
Upper case
letters
Indicate the shortened acceptable form of a command.
Square
brackets
[ ], indicate that enclosed command or command parameters are optional.
Vertical bar |, indicates that one-and-only-one item separated by the vertical bar can be used at any given
time. The vertical bar is read as “or.” For example, ‘A’ | ‘B’ indicates that either A or B can
be chosen, but not both.
Question
mark
?, indicates a query command. Most commands accept this command when it is entered
immediately after the command name. The returned information (<value>) varies in format
according to the type of the field.
Quoted string Fields that accept quoted string parameters will return the active choice in quotes when
queried. For example if the RF generator Output was set to the RF IN/OUT parameter
(RFG:OUTP “RF IN/OUT”) and the queried (RFG:OUTP?), the return would be “RF IN/
OUT”.
Decimal
numeric data
Fields that accept decimal numeric data will return the current field value as an
exponentiated decimal number.
Floating
numeric data
Fields that accept floating point numeric data will return the current field value as a floating
point number in the current
GPIB units.
Character
data
Fields that accept character data (unquoted strings) will return the queried information
without quotes.
