observe voltage, current, and power online for a long time. To use
this feature:

1. Connect the IT-N6900 to the DUT using the appropriate
   cables.
2. Turn on the power supply.
3. On the IT-N6900 interface, select the trend analysis
   function.
4. Observe the voltage, current, and power readings on the HD
   screen in real-time.
5. To save test data, insert a U disk into the USB port and
   configure the data recording interval.

List Programming

The IT-N6900 has a LIST programming function that allows users
to create output change sequences. To use this feature:

1. Access the IT-N6900 programming interface.
2. Create a sequence file by editing the steps for voltage,
   current, time, and cycle.
3. Save the sequence file.
4. Select the desired sequence file for output.
5. The IT-N6900 will output the specified sequence according to
   the programmed steps.

CC&CV Priority

The IT-N6900 supports CC and CV priority modes. To select the
desired mode:

1. Access the IT-N6900 settings menu.
2. Select either CC or CV priority mode.
3. In CC priority mode, there will be no voltage overshoot.
4. In CV priority mode, there will be no current priority.

Foldback Protection

The IT-N6900 provides multiple protection functions, including
OVP/UVP/OCP/OPP/OTP/Foldback. To configure Foldback protection:

1. Access the IT-N6900 settings menu.
2. Enable the Foldback protection function.
3. Set the working mode and protection delay time.
4. When the power supply CV/CC is switched, the output will be
   turned off to protect sensitive DUTs from voltage and current
   overshoot.

Data Logging Function (Trend Analysis)
IT-N6900 supports trend analysis function, allowing end users to observe voltage, current and power online for a long time. Users can save test data in U disk, and the time interval of data recording can be set, which is especially suitable for long-term aging test of production lines or R&D laboratories. HD screen with graphic display, users can observe the abnormal situation of the test in real time.

List programming

V

The LIST programming function of IT-N6900 can provide a maximum of 100 steps of sequence output, and a total of 10 sequence files can be edited. The user can generate various output change sequences by editing the steps such as voltage, current, time and whether to cycle the steps of each single step. The parameters include time units.

CC&CV priority

T1 T2 T3 T4 T1 T2 T3 ……

T

IT-N6900 has CC/CV priority function, which is suitable for complex applications with high speed or no overshoot test requirements. In CV priority mode, you can get faster voltage rising. In CC priority mode, the output current has no overshoot, which can be used to test the DUT of constant current operating characteristics. It is good for applications such as laser testing, integrated circuit testing, charge and discharge testing, power transient simulation and characterization of automotive electronics, etc.

CV priority no voltage overshoot

CC priority no current priority

Foldback
IT-N6900 supports multiple protection functions such as OVP/UVP/OCP/OPP/OTP/Foldback. The Foldback protection function is mainly used to turn off the output when the power supply CV/CC is switched, so as to protect the DUTs which are sensitive to voltage and current overshoot. You can set the working mode and the protection delay time. If the current working mode is changed, the protection will be triggered when the time is up and the output will be turned off.
