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>:ARINC429A:DATA:VALue
"XXXXXXXXXXXXXXX1000" sets the data field value to
XXXXXXXXXXXXXXX1000.
SEARCH:SEARCH<x>>:TRIGger:A:BUS:B<x>:ARINC429A: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.

{ANY|GAP|WORD|PARity}
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A: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).

SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:HIVALue
When the search condition is set to LABel, and the qualifier is set
to either INrange or OUTrange, this command specifies the upper
value of the range for a match on the label field. (Use the command
SEARCH:S
EARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:VALue
to specify the lower value of the range). The default is all X's (don't care).
SEARCH<x> is the search number, which is always 1. B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:VALue
Arguments
QString is a quoted string of 8 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.
Examples
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:HIVALue
"XXXX1000" sets the upper limit of the range to XXXX1000.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:HIVALue?
might return "XXXXXXXX".

SEARCH:SEARC
H<x>:TRIGger:A:BUS:B<x>:ARINC429A:LABel:QUALifier
This command specifies the qualifier to be used when searching on the ARINC429
label field. The search condition must be set to LABel or LABELANDDATA.
The default q
ualifier is "Equal to". SEARCH<x> is the search number, which
is always 1. B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

Arguments
LESSthan sets label qualifier to less than.
MOREthan sets the label qualifier to greater than.
EQual sets the label qualifier to equal.
UNEQual sets the label qualifier to not equal.
LESSEQual sets the label qualifier to less than or equal.
MOREEQual sets the label qualifier to greater than or equal.
INrange sets the l
abel qualifier to in range.
OUTrange sets the label qualifier to out of range.
NOTE. If the sear
ch condition is set to LABELANDDATA, the label qualifier will
be locked to EQual until the search condition is changed again.
