List Displays; Figure 6-11 . Typical List Display Of Timing Activity - HP 1630A Operating And Programming Manual

Model 1630A/D/G
Timing Measurements
List Displays
List displays can be obtained when timing measurements are being performed . Figure 6-11 is a typical list of
timing information captured from a logic software system . The time column shows the absolute time interval
between each line of information and the trigger line .
The message "Continuous Trace in Process" appears at the top of the display when in the [Continuous] trace
mode . In this mode, the analyzer makes a continuous series of single traces, updating the display after it
completes each trace. The content of the list will change after each new trace is completed if the display is
updated with new information . To stop a continuous trace, press the STOP[] key. This causes the analyzer to
complete the trace it has in progress and not to start a new trace.

Display Control Fields
Base :
hexadecimal, decimal, octal, binary, ASCII (for labels from 6 to 16 bits), and
user (values assigned in [User Base] menu) . User values not specified are
shown in hexadecimal numbers.
[Mark] : places asterisk beside each line number that has values specified in [Mark]
line .
[Show] :
shows only those lines on screen that have values specified in [Show] line .
Line no . :
inverse-video field can be changed to any line number in memory . Display
window will shift to area in memory which includes selected line .
Display Information:
Blanked while analyzer gathers activity . If timing activity is captured at a slow
rate, top line will show amount of memory still to be filled . After trace
complete, up to 16 lines of activity from memory will be on screen . Every label
defined in Format Specification will be on screen (subject to max screen
width) . Labels can be reordered by placing cursor in the base field under a
label and pressing the blue SHIFT key plus LABEL right-arrow or left-arrow
key.
Roll Indicator:
arrow(s) in upper right-hand corner . Indicate whether display window can be
positioned up, down, left, or right by ROLL keys .
Time column :
shows absolute time between each sample and trigger line .
