Each number represents how many time segments (each segment on the graph is a unit of time, as
l
defined in the Frequency text field) the voltage lasts for.
The symbol next to the number defines whether the voltage is positive, negative, or zero.
o
A plus symbol (+) is for positive voltage.
l
A minus symbol (-) symbol is for negative voltage.
l
No symbol is for neutral voltage.
l
Examples:
o
"5" means a neutral voltage for 5 Tx clock cycles (shown as 5 columns and dots on the
l
graph).
"+5" means a positive voltage for 5 segments.
l
Use commas to separate segments.
l
For example, "+5,-5" means positive voltage for 5 Tx clock cycles, then negative voltage for 5
o
cycles.
Looped sequences are defined with square brackets.
l
The contents of the loop are contained in square brackets.
o
The number of times the loop is repeated is defined by placing a number after the closing
o
square bracket.
For example, "[+5,-5]2" means a loop that consists of positive voltage for 5 segments, then
o
negative voltage for 5 segments, and is repeated twice (5 positive, 5 negative, 5 positive, 5
negative).
Pulse Sequences
A pulse sequence is the sequence of actions and transmit/receive events carried out by the system. This
includes transmit events, receive events, and modifiers associated with those events.
The sequence is built by assembling and configuring a series of interlocking blocks. Each block represents
an event, or an action applied to an event.
