DC Voltage Current Source/Monitor
6253

Best for development or evaluation of high-precision electronic components
by wide source range and 6½-digit measurement resolution

The DC voltage current source/monitor 6253 is suitable as power source for evaluation of semiconductors and other electronic components and as power source of characteristic systems. In addition to high accuracy, high stability and low noise of our strengths, the 6253 realizes higher precision features such as 5½ digit source resolution, 6½-digit measurement resolution and basis accuracy of ±0.02 %. Furthermore, the 6253 can support various applications by the sweep functions, high-speed pulse measurement function with a minimum pulse width of 25 μs, the variable integration function and the newly adopted variable slew rate function.

Source and measurement functions

Voltage/current source and voltage/current/resistance 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 five sweep types: fixed sweep, linear sweep, log sweep, random sweep (user programmable sweep) and multi-slope linear sweep.

Variable slew rate (SR) function

The rising time and the falling time can be set to any values. (Variable SR)
Four ranges: 10.0 to 99.9 V/s, 100 to 999 V/s, 1.00 to 9.99 kV/s, 10.0 to 99.9 kV/s

Suspend function

The 6253 can select from three output OFF statuses: STBY (output relay OFF), HiZ (output relay ON and high resistance), and LoZ (output relay ON and low resistance). Using this function will prevent throughput reduction due to relay operating time, and extend relay lifetime dramatically, increasing product reliability.
In addition, the setting of a suspend voltage (voltage in HiZ and LoZ status) can prevent transient current from being generated when connecting voltage sourcing devices such as batteries.

HI/LO limit separate setting

In voltage or current source, the HI/LO limit settings are very important. The 6253 has a function that can set the HI and LO limits individually. Furthermore, for the voltage limit, both HI and LO limits can be set homo-polar. This prevents capacitors or batteries from being over-discharged. Also, it is suitable for evaluating devices such as LDs that are used at a constant current and do not tolerate reverse voltage application.
