5 Commands by Subsystem

:TIMebase:MODE

(see page 658)

Command Syntax

:TIMebase:MODE <value>

<value> ::= {MAIN | WINDow | XY | ROLL}

The :TIMebase:MODE command sets the current time base. There are four

time base modes:

• MAIN — The normal time base mode is the main time base. It is the

default time base mode after the *RST (Reset) command.

• WINDow — In the WINDow (zoomed or delayed) time base mode,

measurements are made in the zoomed time base if possible; otherwise,

the measurements are made in the main time base.

• XY — In the XY mode, the :TIMebase:RANGe, :TIMebase:POSition, and

:TIMebase:REFerence commands are not available. No measurements are

available in this mode.

• ROLL — In the ROLL mode, data moves continuously across the display

from left to right. The oscilloscope runs continuously and is untriggered.

The :TIMebase:REFerence selection changes to RIGHt.

Query Syntax

:TIMebase:MODE?

The :TIMebase:MODE query returns the current time base mode.

Return Format

<value> ::= {MAIN | WIND | XY | ROLL}

Example Code

' TIMEBASE_MODE - (not executed in this example)

' Set the time base mode to MAIN, DELAYED, XY, or ROLL.

' Set time base mode to main.

myScope.WriteString ":TIMEBASE:MODE MAIN"

Example program from the start: "VISA COM Example in Visual Basic" on

page 744

NOTE

If a :DIGitize command is executed when the :TIMebase:MODE is not MAIN, the

:TIMebase:MODE is set to MAIN.
