More About Oscilloscope Commands 43
Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 1613
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:
<program mnemonic><terminator>
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:
<program
mnemonic><separator><progra
m
data><terminator>
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>
No space or separator is allowed between the asterisk (*) and the command
header. *CLS is an example of a common command header.
