Page 6: Introduction
Ch10~Ch22 Figure 1: Single-channel Concept Via a SEEG 100E, the system produces arbitrary waveforms (streamed from the PC with digital to analogue conversion) at up to ±1V, which is then applied to a precision 500:1 divider to produce the voltages at up to ±1mV level (2mVpp). The SEEG 100E contains resistor/capacitor networks, dc offset, and relay switching to provide the full range of single channel performance tests in IEC standard. -

Page 11: Cautions
• WhaleTeq does not recommend to connect test equipment with DUT to conduct Electrostatic Discharge (ESD) test. This may cause unexpected damages to test equipment. Please contact WhaleTeq for alternatives before ESD test. -
Page 12: Pc Software Mode
• When the installation is completed, SEEG software would be executed automatically. User can also execute SEEG software via selecting “All Programs” → “WhaleTeq” → “WhaleTeq SEEG” in Windows startup program manager. Relative to normal PC processing, there is no special use of PC speed. However, there has been noted a slow increase in system RAM usage over long periods of time up to 30-40MB (related to MS Windows “garbage collection”). -
