    QST test. ESD option consists of EPS-100 and waveform module. EPS-100 is a power supply, capable of producing +/- 100V with 0.003V resolution. It is universal for all waveform modules. Due to calibration for more precise HBM and MM amplitude, the waveform module may require voltages slightly higher than 100, which is not supported by EPS-100.

    ESD option is ready. You can fire single pulses from File HardwareConfig EPS100Lib User menu, or run an ESD Sweep test. If you are installing the EPS-100 option on the new PC, you need to install the NIDAQmx 9.7 software. The NIDaqmx Core link is available on www.us-isi.com...

    EPS-100 Manual Integral Solutions Int’l August 22, 2013 4. Charge Device Model (CDM) 4.1 Mechanical Alignment According to CDM standard, the head’s suspension must be grounded. In most cases suspension holder serves that purpose, while in other, the suspension is pressed against CDM chassis by flex clamp.

    EPS-100 Manual Integral Solutions Int’l August 22, 2013 4.2 Monitoring Waveform CDM waveform module charges the head to desired voltage and then grounds it, which creates a very fast current transient from the charge accumulated on the head. The pulse is very fast with the rise time up to 500pS and pulse width up to 1nS.
