Compare
Defines the operator for comparison of the decoded data word with the specified data
word.
The following operators can be set: equal, not equal, greater than, lower than, in range
and out of range.
If the data on the selected channel is not relevant for the trigger condition, select "Don't
care".
The setting is relevant for data and window trigger types.
Remote command:
TRIGger:A:I2S:CHANnel:LEFT:CONDition on page 673
TRIGger:A:I2S:CHANnel:RIGHt:CONDition on page 674
TRIGger:A:I2S:CHANnel:TDM<n>:CONDition on page 674
Data / Data Min. / Data Max.
Define the data words to be compared with the decoded data word. The data format is
decimal. The maximum value is limited by the word length. Consider that audio words
are signed numbers in 2's complement format. For example, an 8-bit data word has a
value range from -128 to 127.
The setting is relevant for trigger types data and window.
Remote command:
TRIGger:A:I2S:CHANnel:LEFT:DMAX on page 673
TRIGger:A:I2S:CHANnel:LEFT:DMIN on page 673
TRIGger:A:I2S:CHANnel:RIGHt:DMAX on page 674
TRIGger:A:I2S:CHANnel:RIGHt:DMIN on page 674
TRIGger:A:I2S:CHANnel:TDM<n>:DMAX on page 675
TRIGger:A:I2S:CHANnel:TDM<n>:DMIN on page 675
Combination
Sets the logical combination to trigger on data words on different channels. The instru-
ment triggers if all conditions are met inside one frame.
"And": the instrument triggers if the data conditions on all selected channels are fulfil-
led.
"Or": The instrument triggers if one of the specified data conditions is fulfilled.
The setting is relevant for trigger types data and window.
Remote command:
TRIGger:A:I2S:FUNCtion on page 675
Window Length
Sets the number of subsequent frames (audio samples) for which the data conditions
are fulfilled.
Remote command:
TRIGger:A:I2S:WINDow:LENGth on page 676
Word Select

ger condition.
