29 I2S Triggering and Serial Decode
If you select an "Armed" value that is equal to or greater than the "Trigger"
value, the "Trigger" value will be increased so that it is always greater than
the "Armed" value.
• Decreasing value — similar to the description above except the trigger occurs
on a decreasing data word value, and the "Armed" value is the value to
which the data must rise in order to re-arm the trigger.
6 Press the Base softkey and select a number base for entering data values:
• Binary (2's complement).
When Binary is selected, the Bits softkey appears. This softkey opens the I2S
Bits Menu for entering data values.
When the trigger qualifier requires a pair of values (as with In Range, Out of
Range, Increasing value, or Decreasing value), the first softkey in the I2S Bits
Menu lets you select which value of the pair.
In the I2S Bits Menu, press the Bit softkey and rotate the Entry knob to select
each bit; then, use the 01X softkey to set each bit value to zero, one, or
don't care. You can use the Set all Bits softkey to set all bits to the value
chosen on the 01X softkey. Don't care values are only allowed with Equal or
Not Equal trigger qualifiers.
• Signed decimal.
When Decimal is selected, the softkey(s) to the right let you enter decimal
values with the Entry knob. These softkeys can be Data, <, >, or Threshold
depending on the selected trigger qualifier.

If the setup does not produce a stable trigger, the I2S signal may be slow enough that the
oscilloscope is AutoTriggering. Press the [Mode/Coupling] key, then press the Mode softkey
to set the trigger mode from Auto to Normal.
