Clock Source
Use the clock source (CSOurce) command to select the clock source,
trigger level, and edge polarity for your clock. Before the trigger circuitry
looks for a setup or hold time violation, the clock must pass through the
voltage level you have set.
CSOurce
Use CSOurce to select the channel you want to use for the clock source.
LEVel
Use LEVel to set voltage level on the clock waveform as given in the data
book for your logic family.
RISing or
FALLing
Use RISing or FALLing to select the edge of the clock the oscilloscope
uses as a reference for the setup or hold time violation trigger.
Time
Setup Time
Use SETup to set the amount of setup time used to test for a violation.
The setup time is the amount of time that the data has to be stable and
valid prior to a clock edge. The minimum is 1.5 ns; the maximum is 20 ns.
Hold Time
Use HOLD to set the amount of hold time used to test for a violation.
The hold time is the amount of time that the data has to be stable and
valid after a clock edge. The minimum is 1.5 ns; the maximum is 20 ns.
Setup and Hold
Use SHOLd (Setup and Hold) to set the amount of setup and hold time
used to test for a violation.
The setup time is the amount of time that the data has to be stable and
valid prior to a clock edge. The hold time is the amount of time that the
data waveform has to be stable and valid after a clock edge.
The setup time plus hold time equals 20 ns maximum. So, if the setup
time is 1.5 ns, the maximum hold time is 18.5 ns.
Available trigger conditioning includes HOLDoff and HYSTeresis (Noise
Reject).
