I2S Triggering and Serial Decode
In addition to the standard Time column, the I2S Lister contains these
columns:
• Left Channel — displays the left channel data.
• Right Channel — displays the right channel data.
• Errors — highlighted in red and marked with an "X".
Aliased data is highlighted in pink. When this happens, decrease the
horizontal time/div setting and run again.
Searching for I2S Data in the Lister
The oscilloscope's search capability lets you search for (and mark) certain
types of I2S data in the Lister. You can use the
[Navigate]
key and controls
to navigate through the marked rows.

2 In the Search Menu, press the Search softkey; then, turn the Entry knob
to select the serial slot (Serial 1 or Serial 2) on which the I2S signals
are being decoded.
3 In the Search Menu, press Search ; then, select from these options:
• = (Equal) — finds the specified audio channel's data word when it
equals the specified word.
•
!= (Not Equal)
— finds any word other than the specified word.
•
< (Less than)
— finds when the channel's data word is less than the
specified value.
• > (Greater than) — finds when the channel's data word is greater than
the specified value.
•
>< (In Range)
— enter upper and lower values to specify the range to
find.

to find.
