Header Types

There are three types of headers:

• "Simple Command Header" on page 54

• "Compound Command Header" on page 54

• "Common Command Header" on page 55

See Also • "Combining Commands in the Same Subsystem" on page 55

• "Duplicate Mnemonics" on page 55

Simple Command Header

Simple command headers contain a single mnemonic. AUTOSCALE and

DIGITIZE are examples of simple command headers typically used in this

oscilloscope. The syntax is:

For example:

":AUTOSCALE"

When program data must be included with the simple command header

(for example, :DIGITIZE CHAN1), white space is added to separate the

data from the header. The syntax is:

For example:

":DIGITIZE CHANNEL1,FUNCTION2"

Compound Command Header

Compound command headers are a combination of two 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"
