Channel Notation
The following notation guidelines apply to the contents of the Channel text field within the Manage
Waveform Channels submenu.
Note: This notation also applies to the transmit and receive element selection in
the Pulse Sequences panel, when the aperture is set to Custom. In that panel, it is
used to select elements instead of channels.
Define groups of channels by using the format <start channel>:<step size>:<end channel>.
l
<start channel> is the starting point for the group ("1" for channel 1). The channel specified is
o
included in the group.
<step size> is the number of channels that are skipped before the next channel is selected
o
("1" to count every channel, "2" to count every second channel). If not specified, this field
defaults to 1.
<end channel> is the end point for the group ("128" for channel 128). The channel specified is
o
included in the group.
If the step size in the statement is omitted (such as <start channel>:<end channel>), the
o
system uses a default step size of 1 (every channel).
Individual numbers specify single channels (such as "1" for channel 1)
l
Use commas to separate individual channels or groups of channels (such as 1, 3, 5 for channels 1, 3,
l
and 5)
For example, an entry of "1:2:128" selects all odd channels. This statement selects all channels between 1
and 128 with a step size of 2, which means it selects every second channel after channel 1 (1, 3, 5, etc. until
reaching channel 127).
