Fast transient / burst simulator FNS-AX4-A20 / B63

Fast Transient Burst Simulator(FNS) Fast transient / burst simulator FNS-AX4-A20 / B63

It is compact and equipped with new functions to make EMC testing easier.

It is a tester that evaluates the resistance of electronic devices by simulating high-frequency noise that rises quickly due to discharge between contacts of switching devices and arc discharge generated from electronic motors.

In each test mode screen, you can simply push button on/off and simply enter numerical parameters with the numeric keypad. In addition, all test conditions can be set within 1 to 2 screens.
Screen Configuration

Set either "STANDARD" or "MANUAL" from the menu screen, and make various settings such as test voltage, polarity, frequency, injection phase and so on.

Set either “STANDARD” or “MANUAL” from the menu screen, and make various settings such as test voltage, polarity, frequency, injection phase and so on. “MANUAL” also allows you to set the sweep mode injection. You can save up to 30 test conditions. In “SEQUENCE”, you can load the test conditions set in “MANUAL” and combine the test conditions of maximum 18 steps, and create up to 15 programs. You can also pre-check before starting test.
Easy to perform pre-test inspection with pre-check function

Built-in monitor circuit for pre-check in the tester body.

Built-in monitor circuit for pre-check in the tester body. By simply connecting the waveform observation connector and the attached coaxial cable to the CDN OUT or PULSE OUT of the tester, you can easily check whether the pulse is output normally. You can easily perform pre-start inspection without using a dedicated attenuator or oscilloscope.
* Note: this is not a calibration of the tester.
Simple and Easy EUT power line connection

Injection phase indicator on front panel

In order to prevent mistakes in the connection of the power cable during the test, front panel shows the connection destination at a glance. Also an outlet box (option) is available for the simple power connection.
Coupling Balun available for normal mode test

IEC 61000-4-4 standard has the provision of the common mode test only, but noise may enter the equipment in the normal mode in the field and malfunction may occur.

IEC 61000-4-4 standard has the provision of the common mode test only, but noise may enter the equipment in the normal mode in the field and malfunction may occur. ANSI C37.90.1 standard specifies for corresponding normal mode noise testing. FNS-AX4 can now perform the normal mode test complying with ANSI C 37.90.1 standard with an optional dedicated normal mode coupling balun.
Easy to understand "multi-language" test settings

Operation settings are available in English, Japanese, Korean, and Chinese for easy understanding of the test setting and operation.
