SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:ETHERnet:CONDition
Arguments
SFD — Start of frame delimiter.
MACADDRess — MAC addresses field.
MACLENgth — MAC length/type field.
IPHeader — IP header field. This argument is only available when PROTOCOL
issettoIPv4(usingthecommandBUS:B<x>:ETHERnet:PROTOcol).
TCPHeader — TCP header field. This argument is only available when
PROTOCOL is set to IPv4 (using the command BUS:B<x>:ETHERnet:PROTOcol).
DATa — TCP/IPv4 or MAC protocol client data field. Use the command
BUS:B<x>:ETHERnet:PROTOcol to specify either TCP/IPv4 or OTHER. If the
protocol is set to
OTHER, then DATa refers to the MAC client data.
EOP — End of Packet field.
IDLe — Idle field.
FCSError — Frame Check Sequence Error (CRC) field.
QTAG — IEEE 802.1Q (VLAN) control information field. In order to use
QTAG as a trigger condition, the frame type must be set to QTAG (using
TRIGger:A:BUS:B<x>:ETHERnet:FRAMETYPe ).
Examples
TRIGger:A:BUS:B1:ETHERnet:CONDition MACADDRess sets the trigger
field to
MACADDRess.
TRIGger:A:BUS:B1:ETHERnet:CONDition? might return DATA.
TRIGger:A:BUS:B<x>:ETHERnet:DATa:HIVALue
When the Ethernet trigger condition is set to DATa, and the qualifier is set to
either
INrange orOUTrange, this command specifies the upper data value of the
range. (Use the command TRIGger:A:BUS:B<x>:ETHERnet:DATa:VALue to
specify the lower limit of the range.) The default is all X’s (don’t care).
B<x> is
the bus number B1-B4.
Conditions
This command requires a DPO4ENET application module for DPO/MSO4000B
and MDO4000/B/C models.

TRIGger:A:BUS:B<x>:ETHERnet:QUALifier
Arguments
QString is a quoted string whose length varies depending on the size setting, up
to 32 bits. (Use the command TRIGger:A:BUS:B<x>:ETHERnet:DATa:SIZe to
specify the s
ize.) 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
TRIGger:A:BUS:B1:ETHERnet:DATa:HIVALue
“XXXXXXXXXXXXXXXXXXXXXXXX00001000” sets the upper limit of the
range to XXXXXXXXXXXXXXXXXXXXXXXX00001000 (when the trigger
condition is set to
DATa, and the qualifier is set to INrange or OUTra nge).
TRIGger:A:BUS:B1:ETHERnet:DATa:HIVALue?
might return
“XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX”
TRIGger:A:BUS:B<x>:ETHERnet:DATa:OFFSet
When the Ethernet trigger condition is set to DATa, this command specifies where
in the data field to look for the data trigger value. It specifies the offset into the
data field, in bytes, where the value will be matched. The default is —1 (don’t
care).
B<x> is the bus number B1-B4.
Conditions
This command requires a DPO4ENET application module for DPO/MSO4000B
and MDO4000/B/C models.

Commands Listed in Alphabetical Order
Arguments
<NR1> is an inte
ger whose minimum and default values are -1 (don't care) and
maximum is 1,499.
Examples
TRIGger:A:B
US:B1:ETHERnet:DATa:OFFSet 36
sets the data offset to 36
bytes.
TRIGger:A:BUS:B1:ETHERnet:DATa:OFFSet? might return –1, indicating
that the data offset value is the default value, –1, meaning “don’t care”.
TRIGger:A:BUS:B<x>:ETHERnet:DATa:SIZe
When the Ethernet trigger condition is set to DATa, this command specifies the
number of contiguous TCP/IPv4/MAC client data bytes to trigger on.
B<x> is
the bus number B1-B4.
Conditions
This command requires a DPO4ENET application module for DPO/MSO4000B

TRIGger:A:BUS:B<x>:ETHERnet:QUALifier
Arguments
The minimum and default values are 1 and maximum is 16, except when the
qualifier is set to Inside Range or Outside Range. In these cases, the maximum
size is 4.
Examples
TRIGger:A:BUS:B1:ETHERnet:DATa:SIZe 4 sets the oscilloscope to trigger
on 4 contiguous data bytes.
TRIGger:A:BUS:B1:ETHERnet:DATa:SIZe? might return 6, indicating that
the oscilloscope is set to trigger on 6 contiguous data byte
s.
TRIGger:A:BUS:B<x>:ETHERnet:DATa:VALue
When the Ethernet trigger condition is set to DATa, and the qualifier is set to
LESSthan, MOREthan, EQual, UNEQual, LESSEQual or MO REEQual,
this command specifies the value to trigger on. When the Ethernet trigger
