Level Trigger Settings
To specify the details of the level trigger, click Level Trig – Property in Trigger dialogue.
The settings in the above dialog box are such that recording starts when the input signal of channel 2
crosses from a value lower than +50% of the specified input range to one that is higher than +50%, AND,
the channel 3 signal crosses from a value that is lower than +50% to a higher one. Recording stops when
the input signal of channel 2 crosses over from higher than -20% of the specified input range to lower than
-20%.
Channel selection
In the list of channels, click the desired channel. Alternatively, select the channel from the drop-down list box
in the lower left of the window.
Select the cross direction:
Up: The condition is regarded as having been satisfied when the input signal crosses from less than the
specified level to a level that is higher. The condition is regarded as not having been satisfied if the specified
level was already higher when the recording-standby status was entered.
Down: The condition is regarded as having been satisfied when the input signal crosses from a higher than
specified level to one that is lower. The condition is regarded as not having been satisfied if the specified
level was already lower when the recording-standby status was entered.
Ignore: The channel is not monitored for the level trigger.
Level settings
The full scale of the specified input range is set at 100% on both the plus and minus sides. You set the
monitoring level for these in the range from -99% to +99%. Enter a minus sign (-) for minus values. In the
above dialog box, when the input range is 10 V, 50% becomes 5 V and -20% becomes -2 V.
Logic
When multiple channels are monitored for Start and Stop, specify whether these are combined using a
logical AND or logical OR.
■ If you specify AND, the channels to be monitored should be in the same slot.
