NSG 4070, The improved version of NSG 2070 is a multifunctional EMC immunity testing system. The NSG 4070 has a very wide frequency range (from 9 kHz to 1 GH2) using module structures with external or internal amplifiers, making it widely applicable: including testing according to IEC 61000-4-6, various high current injection applications, signal generators and power meters for testing systems in IEC61000-4--3. IEC61000-4--20. IEC 61000-4-21 applications, etc. Due to its powerful and easy-to-use firmware, the NSG 4070 can operate independently without the need for an external computer or control software. Of course, it can also be remotely controlled for system operations. By inserting the USB memory into the panel, new test and measurement data can be transferred and saved to generate a test report.
