Command separators

Using a colon ( : )

A colon ( : ) is used to separate a command keyword from a lower- level

keyword. When a colon is inserted between two command mnemonics, the

colon moves the path down one level in the present path (for the specified

root- level command) of the command tree. You must separate command

mnemonics from each other using a colon as shown below:

→ FUNC:RAMP:SYMM 50

An error is generated if you do not use the colon in your command string:

→ FUNC RAMP SYMM 50

→ SYST:ERR?

Typical response:

← –103,"Invalid separator"

Using a semicolon ( ; )

A semicolon ( ; ) is used to separate commands within the same

subsystem, and can also minimize typing. For example, sending the

following command string:

→ FREQ:STAR 10; STOP 1000

... is the same as sending the following two commands:

→ FREQ:STAR 10

→ FREQ:STOP 1000

NOTE

“→” indicates the commands that you send to the U2761A.

“←” indicates the response from the U2761A.

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 168 169
