Digitizers Command Reference
Using This Chapter
This chapter describes the Standard Commands for Programmable
Instruments (SCPI) and IEEE 488.2 Common (*) commands applicable to
the E1563A and E1564A Digitizers. This chapter contains the following

Command Types
Commands are separated into two types: IEEE 488.2 Common Commands
and SCPI Commands.
Common Commands
Format
The IEEE 488.2 standard defines the Common commands that perform
functions like reset, self-test, status byte query, etc. Common commands
are four or five characters in length, always begin with the asterisk character
(*), and may include one or more parameters. The command keyword is
separated from the first parameter by a space character. Some examples
of common commands are: *RST *ESR 32 *STB?
SCPI Command Format The SCPI commands perform functions such as making measurements,
querying instrument states, or retrieving data. The SCPI commands are
grouped into command "subsystem structures". A command subsystem
structure is a hierarchical structure that usually consists of a top level (or
root) command, one or more low-level commands, and their parameters.
The following example shows the root command CALibration and its
lower-level subsystem commands:

:LIMit:FAIL?
:LIMit:LOWer[:STATe] ON | 1 | OFF | 0
:LIMit:LOWer[:STATe]?
:LIMit:LOWer:DATA < value>
:LIMit:LOWer:DATA?
:LIMit:UPPer[:STATe] ON | 1 | OFF | 0
:LIMit:UPPer[:STATe]?
:LIMit:UPPer:DATA <value>
:LIMit:UPPer:DATA?
