Indicators
Activity Indicators:
Provided in the Configuration, State Format, and Timing
Format menus for identifying high, low, or changing states on the inputs.
Markers:
Two markers (X and 0) are shown as dashed lines on the display.
Trigger:
The trigger is displayed as a vertical dashed line in the timing waveform
display and as line 0 in the state listing display.
Marker Functions
Time Interval:
The X and 0 markers measure the time interval between one point
on a timing waveform and trigger, two points on the same timing waveform, two
points on different waveforms, or two states (time tagging on).
Delta States (State Analyzer Only): The X and 0 markers measure the number of
tagged states between one state and trigger, or between two states.
Patterns: The X and 0 markers can be used to locate the nth occurrence of a
specified pattern before or after trigger, or after the beginning of data. The 0
marker can also find the nth occurrence of a pattern before or after the X marker.
Statistics: The X to 0 marker statistics are calculated for repetitive acquisitions.
Patterns must be specified for both markers and statistics are kept only when both
patterns can be found in an acquisition. Statistics are minimum X to 0 time,
maximum X to 0 time, average X to 0 time, and ratio of valid runs to total runs.
Run/Stop Functions
Run:
Starts the acquisition of data in a specified trace mode.
Stop:
In single trace mode or the first run of a repetitive acquisition, STOP halts
the acquisition and displays the current acquisition data. For subsequent runs in
repetitive mode, STOP halts the acquisition of data and does not change current
display.
Data Display/Entry
Display Modes:
State listing; timing waveforms; interleaved, time-correlated
listing of two state analyzers (time tagging on); time-correlated state listing and
timing waveform display (state listing in upper half, timing waveform in lower half,
and time tagging on).
Timing Waveform:
Pattern readout of timing waveforms at X or 0 marker.
Bases: Binary, Octal, Decimal, Hexadecimal, ASCII (display only), and
User-defined symbols.
