Commands Listed in Alphabetical Order
This command sets a global delay time (or distance) for all channel waveforms
between the trigger event and the horizontal reference point for the Main timebase,
which is set with the HORizontal:MAIn:REFPoint command. The minimum
position you can set is limited to one of two settings, depending on the current
hardware con
fi guration:
If there are no sampling modules on extender cables, the minimum horizontal
position is set to the insertion delay of the module having the highest insertion
delay speci
fi cation. This is the typical value, not the actual hardware
minimum value (insertion delay, or the minimum time from an external
trigger event to the
fi rst acquired sample).
If there are one or more sampling modules on extender cables, then the
minimum horizontal position is set to the combined insertion delay and
extender delay of the module having the highest combination of insertion
delay speci
fi cation plus attached extender delay. The minimum horizontal
position governs the smallest horizontal position you can set. Changing
the main timebase position can affect the position of each Mag timebase;
however, Mag timebase positions cannot affect the main timebase position.
Refer to the illustration below for a diagram of the relationships of horizontal
position, horizontal reference point, time of
fi rst point, and time of last point.
