4 - 80 COMMAND REFERENCE

SENSe:SWEep:OFFSet:TIME

Syntax: SENSe:SWEep:OFFSet:TIME <NRf> MINimum MAXimum

<NRf>	The trigger delay time in seconds. A negative value
	causes a pre-trigger view time, whereas a positive
	value causes a post-trigger delay time.
MINimum	Selects the minimum possible pre-trigger view time.
MAXimum	Selects the maximum possible post-trigger delay time.

Query form: SENSe:SWEep:OFFSet:TIME? [MINimum MAXimum]

Response: <NR3>

<NR3> The trigger delay time in seconds.

If MINimum was specified, the minimum pre-trigger view time is returned.

If MAXimum was specified, the maximum post-trigger delay time is returned.

Description:

Controls the trigger delay time for the Main Time Base sweep.The trigger delay time may be positive (post-trigger) or negative (pre-trigger). The post-trigger delay time delays the data acquisition after a trigger. The pre-trigger view time allows for pre-trigger acquisition data. If the oscilloscope is in the analog mode, error -221 "Setting conflict;Digital mode required" is generated.

After a *RST command, the trigger delay is set at a pre-trigger view time of 5 milliseconds (5 divisions). Because the sweep time is set to 10 ms after a *RST, the trigger point is positioned in the middle of an acquisition.

Example:
Send → *RST	Resets the instrument.
Send → SENSe:SWEep:TIME 5E-3	The sweep_time becomes
Send → SENSe:SWEep:OFFSet:TIME -0.001	5 ms; MTB = 0.5 ms/div.
	The pre-trigger view time
Send → SENSe:SWEep:OFFSet:TIME 0.001	becomes 1 ms (-2 div).
	The post-trigger delay time
	becomes 1 ms (+2 div).

Front panel compliance:

The SENSe:SWEep:OFFSet:TIME command is the remote equivalent of the front panel TRIGGER POSITION key.
