Colons and commas can be combined in the same statement to list separate ranges of
o
elements. For example, "1:32, 64:128" means all elements between 1 and 32, and all
elements between 64 and 128.
Constant Offset: Sets a constant offset for the elements specified in the Elements field. I n
l
consecutive increments, it is important to position the Tx and Rx elements relative to each other
(because they are defined as 1:128/1:64), to allow for the absolute positioning of the base elements.
Variable Offset: (Only available when the Tx/Rx event is within an Element Loop) Sets whether the
l
Element loop offset is added to the constant offset when calculating offset increments. This is a drop-
down list with two choices:
Loop: Loop Name: Adds the offset specified in the Element Loop settings to the Constant
o
Offset value.
None: Uses only the Constant Offset value.

Transducer Preview
The graphic at the bottom of this flyout is a preview for which transducer elements are currently selected.
The blue bar represents selected transmit elements.
l
The green bar represents selected receive elements.
l
The arrows show that the elements are changing within the loop, using the variable offset option.
l
They do not appear if the variable offset option is not used.
Set PRI
A Set PRI block sets the pulse repetition interval (PRI) for Tx/Rx events. It applies to events differently,
depending on where it is placed in the pulse sequence.
If it is placed outside a loop (blue block), then it applies to every Tx/Rx event that takes place after it,
l
including events that are in loops.
If it is placed inside a loop (blue block), then it applies to all Tx/Rx events within that loop, but does
l
not apply to events outside that loop.
Interface
When a Set PRI block is selected, the following details appear:
