Source Measure Unit GS610 Generation and Measurement Timing (Source Measure Cycle) Source measure cycle (source & measure at 1 ms minimum) As shown in the figure below, the GS610 is capable of synchronizing the generation and measurement at any operation mode. Generation is started after a source delay with respect to an internal/external trigger. Then, after the time it takes for the source level to stabilize (measure delay) the measurement is carried out over a given integration time. This function is necessary when making measurements by waiting for the load response after applying a pulse....

Zero Generation Function of Voltage and Current The zero generation function of the GS610 enables the generation of the voltage/current zero value as well as the switching of the output condition between high and low impedance. In the zero generation condition, the voltage application or current supply to the load can be stopped with the output relay turned ON. This function avoids the problems of chattering and contact life of the output relay and reduces the ON/OFF operation time of the output. Zero generation of voltage • Low impedance: The current limiter is set to the specified value. •...

Then, constant h is determined from the slope of each characteristics data. In the IB-IC characteristics measurement, a GS610 for base current IB output and a GS610 for collector current IC measurement are operated in sync to measure the characteristics. The VCE-IC characteristics measurement is possible using one GS610 by connecting the GS610 between the emitter and the collector, applying VCE,...

Applications Charge/Discharge Characteristics Measurement of Secondary Batteries (Lithium-Ion or Nickel-Hydride) The GS610 can be used to simulate the charge/discharge operation of secondary batteries such as lithium-ion and nickelhydride batteries. In boost charge operation, constant current charge is carried out using large current in the range of approximately 2C to 5C (2 to 5 times the battery capacity). When the battery voltage reaches a given value, a switch is made to constant voltage operation. In constant voltage charge operation, the charge current gradually decreases. When it decreases...
