Commands Listed in Alphabetical Order
Arguments
QString is a quo
ted string of 19, 21, or 23 bits. The allowable characters are 0,
1, and X. The bits specified in the quoted string replace the least significant bits,
leaving any unspecified upper bits unchanged.
NOTE. The size of the QString is dependent on the data field format selected using
BUS:B<x>:ARINC429A:DATA:FORMAT. Also, the store d QString is reset to its
default value whenever the data field format is changed.
Examples
SEARCH:SEARCH<x>>:TRIGger:A:BUS:B<x>:A RINC429A:DATA:VALue
"XXXXXXXXXXXXXXX1000" sets the data field value to
XXXXXXXXXXXXXXX1000.
SEARCH:SEARCH<x>>:TRIGger:A:BUS:B<x>:A RINC429A:DATA:VALue?
might return "XXXXXXXXXXXXXXXXXXX".
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:ERRTYPE
This command specifies the error type when searching on an ARINC429
bus signal. The search condition needs to be set to ERROR (using
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:CONDition).
SEARCH<x>isthesearchnumber,whichisalways1.B<x>isthebusnumber.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:AR INC429A:ERRTYPE
{ANY|GAP|WORD|PARity}
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:AR INC429A:ERRTYPE?
Arguments
ANY sets the error type to match any of the other available error types.
GAP sets the error type to match on gap violations (less than 4 bits idle time
between two packets on the bus).
WORD sets the error type to match on word errors (incorrect number of bits in a
word or bits that violate return to zero transmission).
PARity sets the error type to match on parity errors (parity value results in even
parity count for a word).
