Teseq test system gets telecom surge module

Teseq has upgraded its NSG 3060 with a simple waveform module that generates an open circuit voltage test pulse of 10/700us to test ports intended for connection to symmetrical communication lines.

The telecom surge module - the TSM 3751 - is used in configuration with standard test modules, including EFT and combination wave, to provide testing configurations specifically suited to users' applications.

The TSM 3751 enhances Teseq's NSG 3060 test system, which features a modular architecture to cost-effectively meet the needs of basic as well as sophisticated test laboratories.

The module is said to easily fit into the NSG 3060 to provide a fast and convenient test setting that allows users to select source impedance from either 15ohms or 40ohms by simply pressing a button on the generator's colour LCD touch screen.

It can also be placed into an expansion housing controlled by the generator's touch screen or via the Win 6000 software.

The surge module adheres to several industry standards, including IEC/EN 61000-4-5:2005 and IEC 60060-1, ITU-K series and ANSI/IEEE C62.41.

It meets the latest ISC short-circuit current pulse form requirement of 5/320us, easily satisfies IEC requirements up to 4kV and surpasses the UL 1950 safety test recommendation of 7kV.

In addition, when tolerance is taken into account, the TSM 3751 is compliant with ANSI-TIA-968-B, covering the 9/720us pulse form.

The TSM 3751 has a voltage range of 200V to 7,700V in 1V steps as well as positive, negative and alternating polarity with floating pulse outputs.

Minimum repetition time for voltages up to 4,400V is 20sec and 30sec with a voltage range from 4,401V to 7,700V.

Maximum repetition time is 600 seconds.

The TSM 3751 has an asynchronous coupling mode.
