Conditions
For I

C or SPI bu
s signals, install the DPO4EMBD application module,
except for MDO3000 models, which require MDO3EMBD.
For RS-232, RS
-422, RS-485, or UART bus signals, install the DPO4COMP
module, except for MDO3000 models, which require MDO3COMP.
For I
2
S, Lef
t Justified (LJ), Right Justified (RJ), or TDM bus signals, install
the DPO4AUDIO module, except for MDO3000 models, which require
MDO3AUDIO.
For CAN or LIN bus signals, install the DPO4AUTO or DPO4AUTOMAX
module, except for MDO3000 models, which require MDO3AUTO.
For FlexRay bus signals, install the DPO4AUTOMAX module, except for
MDO3000 models, which require MDO3FLEX.
For Ethernet signals on the MDO4000/B/C and MSO4000B and DPO4000B,
install the DPO4ENET module. Note that ≥350 MHz bandwidth models
are recommended for 100BASE-TX.
For MIL-STD-1553 bus signals, install the DPO4AERO module, except for
MDO3000 models, which require MDO3AERO.
For USB bus signals, install the DPO4USB module, except for
MDO3000 models, which require MDO3USB. Note that 1 GHz bandwidth
models are recommended for high-speed (HS) USB.
A table is available listing the commands enabled by each application module.

FLEXRay specifi
es the FLexRay bus.
AUDio specifies the audio bus.
ETHERnet specifies the Ethernet bus.
MIL1553B specifies the MIL-STD-1553 bus.
TRIGger:A:BUS:B<x>:ARINC429A:CONDition
This command sets the condition (word start, label, matching data, word end, or
error) to b
e used to trigger on CAN bus data. B<x> is the bus number.
Conditions
This command requires installation of a DPO4AERO application module for
MDO4000C models, or MDO3AERO for MDO3000 models.

TRIGger:A:BUS:B<x>:ARINC429A:ERRTYPE
BUS:B<x>:ARINC429A:SOUrce
Arguments
STARt enables triggering on the first bit of a word.
END enables triggering on the 32nd bit of a word.
LABel enables trigger on a matching label.
DATA enables triggering on matching packet data field(s).
LABELANDDATA enables triggering on matching label and matching packet data
field(s).

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

TRIGger:A:BUS:B<x>:ARINC429A:DATA:VALue
Arguments
QString is a quoted string of 19, 21, or 23 bits. The allowable characters are0,
1, and X. The bits specified in the quoted string repla
ce 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
TRIGger:
A:BUS:B<x>:ARINC429A:DATA:HIVALue
"XXXXXXXXXXXXXXX1000" sets the upper limit of the range to
XXXXXXXXXXXXXXX1000.
