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 source function with a minimum pulse width of 25 μs, the variable integration function and the newly adopted variable slew rate function.

• Source and measurement range
  ±2 A at ±32 V
  ±1 A at ±64 V
  ±0.5 A at ±110 V
• Sink-enabled bipolar output

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.

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). Consequently, unnecessary relay ON/OFF operations can be omitted. 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.

The output response of the 6253 can be switched between Fast and Slow. When the output response is set to Fast, the 6253 starts up faster than the former models.
