myScope.WriteString ":TIMebase:REFerence CENTer;POSition 0.00001"

myScope.WriteString ":TIMebase:REFerence CENTer"

myScope.WriteString ":TIMebase:POSition 0.00001"

A second way to send these commands is by placing TIMebase: before the

POSition command as shown in the second part of example 2. The space

after POSition is required.

Example 3:

Selecting

Multiple

Subsystems

You can send multiple program commands and program queries for

different subsystems on the same line by separating each command with a

semicolon. The colon following the semicolon enables you to enter a new

subsystem. For example:

For example:

myScope.WriteString ":TIMebase:REFerence CENTer;:DISPlay:VECTors ON"

Multiple commands may be any combination of compound and simple

commands.

NOTE The colon between TIMebase and RANGe is necessary because TIMebase:RANGe is a

compound command. The semicolon between the RANGe command and the POSition

command is the required program message unit separator. The POSition command does not

need TIMebase preceding it because the TIMebase:RANGe command sets the parser to the

TIMebase node in the tree.

NOTE In the first line of example 2, the subsystem selector is implied for the POSition command in

the compound command. The POSition command must be in the same program message as

the REFerence command because the program message terminator places the parser back

at the root of the command tree.

NOTE The leading colon before DISPlay:VECTors ON tells the parser to go back to the root of the

command tree. The parser can then see the DISPlay:VECTors ON command. The space

between REFerence and CENter is required; so is the space between VECTors and ON.
