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.)
