completed.
Peak Indicates that the marker facility is currently in search track mode and
configured to detect the peak value. The main marker moves to the
peak value on the trace each time one sweep cycle is completed.
D marker mode
DMkr Indicates that the marker facility is currently in default D marker
mode. In this mode, the D marker keeps track of changes to the trace,
maintaining the same position in terms of the sweep parameter value.
Indicates that the marker facility is currently in fixed D marker mode.
FxdD
In this mode, the D marker is fixed at a certain point on the screen,
without reflecting any changes to the trace. It remains in the same
position in terms of both the sweep parameter and measurement
parameter values.
Indicates that the marker facility is currently in tracking D marker
TrkD
mode. In this mode, the D marker appears in the same position as, and
moves synchronously with, the main marker,

8. Marker Statistics/Trace Bandwidth Analysis Fields

These fields show the marker statistics (average, standard deviation, and peak-to-peak
values) or the results of trace bandwidth analysis (bandwidth, center value, Q peak, DL,
and DR) for Traces A and B. When both features are enabled, they display the marker
statistics only.

9. Limit Line Test Fields

These fields show the results of limit line tests as either "PASS" or "FAIL." By performing
a limit line test, you can determine whether the trace of measurement results falls within
your specified limit line.

10. HP Instrument Basic Status Indicator

Indicates the execution status of HP Instrument BASIC.
* HP Instrument BASIC is currently executing a program or command.
You cannot execute an additional command.
_ HP Instrument BASIC has suspended the execution of a program. You
can resume the program using the CONTINUE command.
? HP Instrument BASIC is waiting for a keystroke to continue the
execution of a program. You cannot execute an additional command.
(blank) HP Instrument BASIC is not executing a program or command. You
can use commands other than the CONTINUE command.

11. dc Voltage/Current Bias Monitor Field

This field shows the monitor value (voltage or amperage) for the dc bias conditions that are
currently in effect. For this field to actually display the monitor value, you must apply dc
bias through the keystroke sequence
