In the oscilloscope programmer's documentation, the short form of a

command is indicated by uppercase characters.

Programs written in long form are easily read and are almost

self- documenting. The short form syntax conserves the amount of

controller memory needed for program storage and reduces I/O activity.

Simple Command Headers

Simple command headers contain a single mnemonic. :AUToscale and

:DIGitize are examples of simple command headers typically used in the

oscilloscope. The syntax is:

Simple command headers must occur at the beginning of a program

message; if not, they must be preceded by a colon.

When program data must be included with the simple command header

(for example, :DIGitize CHANnel1), white space is added to separate the

data from the header. The syntax is:

Compound Command Headers

Compound command headers are a combination of two or more program

mnemonics. The first mnemonic selects the subsystem, and the second

mnemonic selects the function within that subsystem. The mnemonics

within the compound message are separated by colons. For example, to

execute a single function within a subsystem:

:<subsystem>:<function><separator><program data><terminator>

For example, :CHANnel1:BWLimit ON

Common Command Headers

Common command headers control IEEE 488.2 functions within the

instrument (such as clear status). Their syntax is:

*<command header><terminator>
