channel offset
0 to (channel length – word length) bits
channel delay

Trigger
trigger events
data, window, word/sync, error condition
data setup
define individual value and condition for
each audio channel; condition =, ≠, >, <,
inside range, outside range, don’t care;
trigger when “all” or “any” audio channel
conditions are met in single audio frame
window setup
audio channel setup same as data setup;
user-defined window length up to
4 000 000 000 frames
word/sync setup
rising edge, falling edge
Decode
displayed signals
bus signal, stacked bus signal, logic signal
color coding of bus signal
color-coded audio channels
displayed format of data
hex, signed decimal, binary, ASCII
frame table
decode results displayed as tabulated list
with timestamp; frame navigation; data
export as CSV file
track of audio waveform
displays audio channel content as a
waveform that is time-correlated to the
source signals; user can activate, scale
and position each audio channel
individually
