:TIMebase:MODE
(see page 530)
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 (delayed) time base mode, measurements are
made in the delayed 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><NL>
<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.

NOTE If a :DIGitize command is executed when the :TIMebase:MODE is not MAIN, the
:TIMebase:MODE is set to MAIN.
