Source and measurement functions
Voltage/current source and voltage/current measurement can be selected by specifying the source and measurement functions.
Voltage and current source mode
There are four source modes; DC, pulse, DC sweep, pulse sweep. Then, the sweep modes are classified into three sweep types: linear sweep, log sweep and random sweep (user programmable sweep).
The 6243/6244 can generate patterns necessary for device test without exchanging data with an external controller, and read out measurement results from the memory after the test. However, it cannot generate pulses across polarities.
Source and measurement timing
In the pulse and sweep modes, the source and measurement timings are synchronous, and measurement can be done after a specified time from source value application. Setting the measurement delay (Td) allows measurement after a specified time from the end of pulse application as stress test.
Range switching without discontinuity
The voltage and current source ranges can be changed without lowering the output to zero from the level before switching. This allows no discontinuity at the output and reduces adverse effects on devices with hysteresis or high dielectric constant.
The performance of a power supply basically depends on the accuracy of source voltage/current and the quantity of noise superimposed to them. The 6243/6244 adopts a minimum noise design effective for input signals of a DC amplifier and other cases susceptible to power noise. This model is the perfect power supply for linear ICs, optical devices or mobile communication amplifiers.
