Basic Operation

6.8 Select Trigger Source (Trig Source)

For the IT6000B series power system, the List and data logging functions can

be triggered for running by the following methods:

• Immediate: Perform a trigger operation immediately.

• Manual: Default value, indicates the trigger occurs when the

[Shift]+[On/Off] (Trigger) keys are pressed from the front panel.

• Bus: Indicates the trigger occurs via the communication cables. When the

trigger command *TRG is received, the IT6000B instrument generates a

trigger.

• Voltage (only available in DLogTrig Source): Voltage trigger.

When the DC terminals detect that the voltage reaches the trigger voltage

setting value and is within the range of the upper and lower trigger limits, a

data recording operation is triggered.

– Level: Trigger threshold.

– Up-Level: Trigger upper limit value.

– Down-Level: Trigger lower limit value.

• Current (only available in DLogTrig Source): Current trigger.

When the DC terminals detect that the current reaches the trigger current

setting value and is within the range of the upper and lower trigger limits, a

data recording operation is triggered.

– Level: Trigger threshold.

– Up-Level: Trigger upper limit value.

– Down-Level: Trigger lower limit value.

• External: Indicates the trigger occurs via the pin 4 of the digital I/O interface

(P-IO).

For details, see 6.11.4 IO–4. Ext-Trig, Not-Invert.

The List function and the data logging function have the same steps for select-

ing the trigger source. They need to be set separately in different menu items

(ListTrig Source and DLogTrig Source). Therefore, this section takes the List

trigger source setting as an example to introduce the operation steps.

1. Press the composite keys [Shift]+[P-set] (System) on the front panel to en-

ter the system menu.

2. Press the Up/Down key or turn the knob to select the ListTrig Source and

press [Enter].
