Sampling target
The probe item to be sampled with the digital oscilloscope is set in the probe settings. 16 channels can be set for probe items
in word data, and 16 channels can be set for bit data for each sampling settings file. The following data is set in the probe
settings.
*1 Refer to device list for the range of devices that can be set. (Page 75 Device List)
Trigger settings
Trigger condition settings
Trigger conditions are set to turn ON the trigger. The following items are set in the trigger condition settings.
■Data conditions
• Trigger mode setting
Select the conditions used to turn ON the trigger with trigger conditions set for each channel.
The establishment of trigger conditions set for each channel is judged with either the OR condition or AND condition. OR
and AND conditions cannot be combined and used for each channel.
• Trigger conditions
Trigger conditions are set for each channel. The number of channels for which trigger conditions are set is 16 channels in
word data, and 16 channels in bit data. (for number of probe settings)
Type Range
Word data Servo control data Selected from probe item list.

Condition Details
OR condition The trigger turns ON if any of the conditions for each channel data are established.
AND condition The trigger turns ON if all of the conditions for each channel data are established.
(1) Bit trigger pattern
Pattern Details
No setting
ON When the channel value is ON
OFF When the channel value is OFF
When the channel value changes from OFF to ON
When the channel value changes from ON to OFF
(2) Word trigger pattern
These are the conditions when compared with the value specified for the trigger reference value (trigger value).
Pattern Details
Increase direction When the channel value changes from a value smaller than the trigger value to the trigger value or greater
Decrease direction When the channel value changes from a value greater than the trigger value to the trigger value or smaller
Increase or decrease direction When the channel value changes from a value smaller than the trigger value to the trigger value or greater, or from a
value greater than the trigger value to the trigger value or smaller
