Arguments
<QString> is a t
ime in the form "hh:mm:ss" where hh refers to a two-digit hour
number, mm refers to a two-digit minute number from 00 to 59, and ss refers to a
two-digit second number from 00 to 59.
Examples
TIME "14:00:00" sets the time to exactly 2:00 p.m.
TIME? might return :TIME "14:05:17” indicating the current time is set to 2:05
p.m. and 17 seconds.
TOTaluptime? (Query Only)
This query returns the total number of hours that the oscilloscope has been
powered on since the nonvolatile memory was last programmed (usually sincethe
initial manufacturing process).

TRIGger FORCe
TRIGger?
Arguments
FORCe creates a trigger event. If TRIGger:STATE is set to READy, the acquisition
will complete. Otherwise, this command will be ignored.
Examples
TRIGGER FORCE forces a trigger event to occur.
TRIGger:A
Sets the A trigger level automatically to 50% of the range of the minimum and
maximum values of the trigger input signal. The query returns current A trigger
parameters. The trigger level is the voltage threshold through which the trigger
source signal must pass to generate a trigger event. This command w
orks for the
following cases: Edge Trigger (when source is not AC line or power), Logic
Trigger (when Clock Source is not Off or Logic Pattern is Don't Care), and Pulse
Width Trigger.

Arguments
SETLevel sets the A trigger level to 50% of the range of the minimum and
maximum values of the trigger input signal.
Examples
TRIGGER:A SETLEVEL sets the A trigger level to 50% of the range of the
minimum and maximum values of the trigger input signal.
TRIGGER:A? might return a long response with A trigger parameters,
