The sources of the serial bus are channel signals: use BUS<m>:...:SOURce
commands.
●
Decoding is enabled: BUS<m>[:
STATe] is set to ON.

TRIGger<m>:MDIO:TYPE <Type>
Selects the trigger type for MDIO analysis.
Parameters:
<Type> STARt | STOP | DATA
ST
ARt
Sets the trigger to the start of frame (SOF) field. The start of
frame condition and the trigger instant is the end of the pream-
ble. Trigger pattern: preamble (32 bits "1")
STOP
Sets the trigger to the end of frame (EOF) field. The trigger
instant is after the last data bit. Trigger pattern: preamble
(32 bits "1") + 32 bits "X"
DATA
Sets the trigger to the data field. For more information on the
data condition, see MDIO in the Ethernet standard. The trigger
instant is at the end of the frame after the last data bit, as indica-
ted in the GUI. Trigger pattern: preamble (32 bits "1") + 2 bits
"ST" (Start of Frame Code) + 2 bits "OP" (Frame Type Code, or
"OpCode") + 5 bits "PHYAD/PRTAD" (Physical Layer Entity
Address / Port Address) + 5 bits "REGAD/DEVAD" (Register
Address / Device Address) + 2 bits "TA" (turnaround time, X bits)
+ 16 bits "DATA/ADDRESS"
*RST: STARt
TRIGger<m>:MDIO:ST <StartCode>
Selects the start of frame code of the frame pattern; available only in trigger type
"Data".
Note that Clause 22 is coded by "01", while Clause 45 is coded by "00", thus the lower
Clause number is represented by the higher parameter value.
Parameters:
<StartCode> ST00 | ST01 | ST0X
ST00
Clause 45
