N sample acquisition mode is activated when the analog input exceeds the specified threshold
value. The analog threshold trigger is activated when the input signal exceeds a set voltage value,
either higher or lower. This trigger can also be utilized to detect instantaneous changes in a
continuous voltage signal. The user has the flexibility to specify the desired trigger condition.
In N-Sampl Acquisition Mode, the following parameters need to be specified:
 Channels：Select the number of channel to be enabled.
 Trigger：Select Analog threshold trigger as the trigger type.
 Sample Rate：Specify a value of the sample rate from 0 to 128000.
 Sample Count：Specify a value of the target sample from 0 to 15000000. 0 means keep collecting
data until stop command is received.
 High Level/Low Level：Specify a value of the analog threshold trigger high/low level from +10 to
-10.
 AI Mode：Select the analog threshold trigger conditional and specify a value of the left/right
