Couple levels (Trigger level and hysteresis coupling)
Sets the trigger levels and hysteresis values for all channels to the values of the cur-
rently selected trigger source. The function affects only the levels defined for the
selected condition. The hysteresis of the external trigger input is an independent value,
and it is not affected by level coupling.
In trigger sequences, another coupling of trigger levels is possible: "Couple sequence
thresholds" on page 249.
Remote command:
TRIGger<m>:SCOupling on page 1273
Setup time
Sets the minimum time before the clock edge while the data signal must stay steady
above or below the data level.
The setup time can be negative. In this case, the hold time is always positive. If you set
a negative setup time, the hold time is adjusted by the instrument.
Remote command:
TRIGger<m>:SETHold:STIMe on page 1272
Hold time
Sets the minimum time after the clock edge while the data signal must stay steady
above or below the data level.
The hold time can be negative. In this case, the setup time is always positive. If you set
a negative hold time, the setup time is adjusted by the instrument.
