Setting Up the Display of Measurement Results
Monitoring the dc Bias Level
trace is currently active.
Traces A and B are each associated with a field called "Marker Statistics/Trace Bandwidth
Analysis." Each of these fields can be used to display one of three types of marker-based
monitoring information: the test signal voltage level, the test signal current level, and the
dc bias level (voltage or current). For more information on marker-based monitoring of the
test signal level, refer to "Monitoring the Test Signal Level (AC)" on page 189.
The Marker Statistics/Trace Bandwidth Analysis field for each trace is used to display one
of three types of information: (1) the level value monitored at the marker position, (2) the
marker statistics, and (3) the results of trace bandwidth analysis; the parenthesized
numbers denote the precedence among these information types when more than one of
them are enabled at the same time.
