PurePulse

A flexible and efficient ESD tester capable of testing devices and wafers 

PurePulse is a flexible and efficient ESD tester capable of testing devices and wafers.  PurePulse generators include: Human Body Model (HBM), Machine Model (MM), Transmission Line Pulsing (TLP), Very Fast Transmission Line Pulsing (VF-TLP) and Human Metal Model (HMM).

 

Its 2-pin style setup reduces tester parasitics, it captures waveform data, and can be automated to test thousands of pins.  Our PurePulse system was designed from the ground up to be customized to meet your testing needs, take a look at the features below and schedule a demo with us to learn more.

Why choose GTS?

Innovative and new performance features

GTS offers innovative and new performance features that have been developed with industry leaders, who often have special requirements for their leading-edge products.  We have built TLP systems with unique features for companies including Intel and T.I. and have co-authored papers with organizations like IBM and RFMD (Qorvo).

Flexible probes and TLP configurations

While other companies supply their own probes or only support one brand, GTS can adapt testing to use many commercial probes.  Based on the probe type used, we can provide TDR, TDR-O, TDR-S, TDRT and TDT configurations to meet specific needs such as high voltage parts and MEMS.

Pioneers in the use of Kelvin probes

°K

GTS's Evan Grund wrote the first paper on Kelvin probes for TLP, paving the way for this technique to become almost universally accepted as the best way to measure voltages accurately with both TLP and VF-TLP.  Our VF-TLP focuses on the use of Kelvin probes which we have refined over the years to avoid contact resistance effects. Unless Kelvin probing is used, contact resistance will always be present regardless of the materials used, and will always vary, preventing accurate calibrations and affecting measurements.

Flexible software

GTS has always focused on providing capable and flexible software. This has allowed us to easily adapt to special measurements such as incorporating multiple bias supplies, function generators, different oscilloscopes, and network analyzers. 

Modularity and Expandability

At GTS we have built our TLP systems as modules based on PurePulse family architecture. This means that GTS systems with both TLP and VF-TLP share a control computer and resources such as high voltage supply and SMUs. Other companies that configure their TLP and VF-TLP systems as two separate complete, stand-alone systems require two computers and two scopes in addition to the two pulsers. 

 

GTS PurePulse systems are based on modules, with each module containing a single-board computer.  All modules, scopes, and other equipment communicate on a local network using TCP/IP for reliability.  Other ESD pulse measurement modules (HMM, HBM, and MM) can also be added.  GTS’s design also allows test waveform switching under computer control without the need to re-cable the test system for different tests.

Automation

We integrate our equipment with probe stations, and have GTS has added equipment to Suss, FormFactor (Cascade Microtech) and other prober suppliers. Our partnership with Signatone offers turn-key ESD Workbench systems for automated wafer and packaged part testing.  Maestro software can control the probe station motions and also drive motorized positioners. 

PurePulse Features

What equipment do I need?


The Dronfield Yoga and Wellbeing Studio has mats and other props for you to borrow, although you are welcome to bring your own. For my classes at the Adventure Hub in Bamford, I can provide you with a mat, strap, bricks and blocks if you need them. A blanket is useful for padding and to keep you warm during relaxation. I do encourage you to have your own equipment (I can help you with this).




Do I need to book?


Yes. For classes at the Dronfield Yoga and Wellbeing Studio please click on the link to book on their website. For classes at the Adventure Hub in Bamford please contact me to book you place. Class sizes are limited. Payment can be done via online banking, in cash or card at the venue.




What sort of yoga do you teach?


My classes are based in the Hatha tradition. Hatha Yoga is what comes to mind when you think of yoga in general terms. It involves the breath, the body and the mind. Mindful movements, postures, sequences, breath-work, meditation and relaxation all feature in my 90 minute classes. My classes are for everyone, I offer plenty of variations for postures so that you can find what feels good in your body. One of my mantras is to move in a wide variety of ways and my classes certainly encompass this ideal. I work in blocks of six weeks where a rounded practice is explored through a specific theme. Throughout the weeks movements, postures and dynamic sequences are developed to build strength, flexibility and stability. I also teach Yin Yoga which is a complementary, slower style where seated and laying postures are held for longer periods of time. This works into the deeper tissues of the joints and ligaments. Yin Yoga is an excellent way to improve your mobility and to calm the mind.




Are your classes suitable for beginners?


Yes, beginners and those with experience are most welcome to my classes. I offer lots of variations and alternatives for poses. I ask that you listen to your body and work to your approriate edge, ensuring that what you do is safe and feels good.
