In input: display the state applied to Pin (binary bit 0 or 1).
Out output: binary bit 0 or 1 can be set.
11.2.2 Digital input
Select Digital In, Pin 1-Pin3 can be set as digital input.
Polarity: Set the Pin polarity to positive or negative.
In: display the state applied to Pin (binary bit 0 or 1).
11.2.3 Trigger output
Select Trigger Out, Pin1-Pin3 can be set as trigger output. This function is used in
conjunction with the list output (BOST/EOST).
The Pin assigned this function will output a pulse signal of about 5ms.
Polarity: Set the Pin polarity to positive or negative, that is, the trigger output pulse is
positive or negative.
Trigger output operation example:
1. Connect Pin1 to the display device
Pin1 is connected to the input terminal of the oscilloscope as the trigger output terminal,
and the common ground terminal is connected to the ground of the display device.
2. IO function settings
Pin1 function select "Trigger out", Pin1 polarity is set to positive. Refer to the "
Output List "
chapter to set the output list, and check "BOST" or "EOST".
3. Trigger output
Turn on the channel output and execute the list output "Run/Stop". After the trigger occurs,
the oscilloscope displays a positive pulse at each trigger response point set.
11.2.4 Trigger input
Select Trigger In, Pin 1-Pin3 can be set as trigger input. This function is used in conjunction
with the list output (trigger source is set to DIO Trigger In under the property menu). When
an external digital signal is input from the specified Pin, a trigger occurs and the output is
set according to the list.
Polarity: Set the Pin polarity to positive or negative.
In input: display the relative status of the input level.
Trigger input operation example:
1. Connect Pin1 to a digital signal generator
Pin1 is used as the trigger input interface, and the common ground is connected to the
ground of the digital signal generator.
2. IO function settings
Pin1 function select "Trigger in", Pin1 polarity is set to positive. Refer to the "
Output List "
chapter to set the output list, and select "DIO Trigger In" as the trigger source in the
"Properties".
