15.5: Trace Time, Sample Rate and Single Trace
Trace Time sets the length of the recorded trace.
Sample Rate is the rate at which the signals are sampled. The rate depends on the trace
time, the number of channels selected, and which variables are being traced.
Single Trace puts the scope in a single trace mode of operation. In this mode, the trigger
is not re-armed after a trace until the user presses the Record button. Single Trace is
automatically set by the generators in certain cases.
15.6: Scope Display Parameters
The user can set the line style and other scope screen preferences. Right-click on the
