13.Waveform Comparison /
Waveform and Displacement Comparison Mode
13-1. Function
In the Waveform Comparison mode, waveforms changing with time (or displacement)
are sampled to make High/Low Limit Comparisons based on the sampled waveforms.
Sequential comparisons can be made with dynamically changing waveforms.
The point where the High/Low Limit Waveform is exceeded for the first time is
displayed on the graph with a "+" mark.
Also, any one of hold operations: Sample Hold, Peak Hold, and Valley Hold can be
executed simultaneously with the Waveform Comparison operation.
13-2. Setting and Operating Method
1. Decide Channel Number Selection in Code Setting, and set the following items.
・
Select Analog CH
(in the Waveform Comparison mode. CH1 is fixed in the Waveform and Displacement
Comparison mode. See "7-4. X/Y-axis Setting by Operation Mode and Input CH"
P41.)
・
Level Axis Select
("Y-axis" is fixed in the Waveform Comparison mode. See "16-2-9. Level Axis Select
/ Waveform Start Level / Waveform Termination Level / Hold Start Level" P113.)
・
Waveform Start Level
(unnecessary when used with the input signal "Capture start by external signal" ON.
See "16-2-9. Level Axis Select / Waveform Start Level / Waveform Termination Level
/ Hold Start Level" P113.)
・
Waveform Termination Level (unnecessary when used with the input signal "waveform
termination level operation" OFF. See "16-2-9. Level Axis Select / Waveform Start
Level / Waveform Termination Level / Hold Start Level" P113.)
・
For executing any hold operation, also set the following two items.
(See "13-7. Hold Operation" P78.)
i.
Hold Setting (See "16-2-4. Hold Setting" P105.)
ii. HI-HI Limit / LO-LO Limit (See "16-2-7. High Limit / Low Limit / HI-HI/LO-
LO Mode / HI-HI Limit / LO-LO Limit" P109.)
