Programming instructions

Commands and Queries
The following tables facilitate easy access to each command and query for
the HP 54645A/D Oscilloscopes. The commands and queries are divided into
separate categories with each entry alphabetized.
The arguments for each command list the minimum argument required. The
part of the command or query listed in uppercase letters refers to the short
form of that command or query. The long form is the combination of the
uppercase and lowercase letters. The NR1 and NR3 formats refer only to the
Query Return values. Input arguments are not restricted by these formats.
These commands also show specific information about how the command
operates on a particular oscilloscope model. For additional information, refer
to the online Oscilloscopes Programmer’s Reference.
