The settings are relevant for trigger types Data, Window and Frame condition.
"Operator"
Defines the operator to set a specific data word ("Equal" or "Not
equal") or a data range.
"Min data"
Defines the data pattern. The data length is limited to the word length.
Enter the pattern using the bit order defined in the signal configura-
tion. X (don't care) is not allowed.
In binary format, use the following characters: 1; 0; or X (do not care).
To enter the pattern in other formats use the bit pattern editor, see
Chapter 13.1.5, "Bit pattern editor", on page 521.
"Max data"
The second data pattern is required to specify a range with conditions
"In range" and "Out of range".
Remote command:
TRIGger<m>:I2S:TCONdition<n>:CONDtion on page 1599
TRIGger<m>:I2S:TCONdition<n>:DMIN on page 1600
TRIGger<m>:I2S:TCONdition<n>:DMAX on page 1600
Window length
Sets the number of words that is used as time limit for the "Window" trigger type. The
instrument triggers if the data condition is fulfilled on the same channel for the given
number of subsequent frames.
Remote command:
TRIGger<m>:I2S:SOWords on page 1601
Word select: Slope
Sets the edge of the WS or FSYNC signal as trigger condition. The instrument triggers
on the first clock edge after the specified edge.
Figure 13-38: Word select trigger on I²S standard signal with clock polarity "Rising" and "Normal"
WS polarity (left = 0)
The WS edge indicates the start of the left or right channel. The FSYNC edge indicates
the frame start.
Consider the WS / FSYNC Polarity setting in the "Protocol Configuration" dialog box.
