6.3.10 Data2Clock trigger
Access: [TRIGGER] > "Setup" tab > "Type = "Data2Clock""
With the "Data2Clock" trigger you can analyze the relative timing between two signals:
a data signal and the synchronous clock signal. Many systems require, that the data
signal must be steady for some time before and after the clock edge, for example, the
data transmission on parallel interfaces. With this trigger type, you can also test the
time correlation of sideband and in-band signals.
This trigger type is also known as setup/hold trigger.
The trigger occurs if the data signal crosses the data level during the setup and hold
time. The reference point for the time measurement is defined by clock level and clock
edge.
Clock source
Selects the input channel of the clock signal.
Remote command:
TRIGger<m>:DATatoclock:CSOurce[:VALue] on page 1183
TRIGger<m>:SPATtern:CSOurce[:VALue] on page 1190
Clock edge
Sets the edge of the clock signal to define the time reference point for the setup and
hold time:
"Positive"
Rising edge, a positive voltage change.
"Negative"
Falling edge, a negative voltage change.
"Both"
Both the rising and the falling edge.
Remote command:
TRIGger<m>:DATatoclock:CSOurce:EDGE on page 1183
Clock level
Sets the voltage level for the clock signal. Both "Clock level" and "Clock edge" define
the starting point for calculation of the setup and hold time.
Remote command:
TRIGger<m>:DATatoclock:CSOurce:LEVel on page 1184
