The DC voltage current source/monitor 6253/6254 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 6253/6254 realizes higher precision features such as 5½ digit source resolution, 6½-digit measurement resolution and basis accuracy of ±0.02 %. Furthermore, the 6253/6254 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 functions

6253 Source and Measurement Functions

Voltage/current source and voltage/current/resistance measurement can be selected by specifying the source and measurement functions. 
The 6253/6254 is equipped with A/D twin converters, allowing parallel measurement of voltage and current  

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.

6253 Voltage/Current Source Mode

Variable slew rate (SR) function

6253 Variable Slew Rate (SR) Function

The vairable slew rate function allows the rising time and the falling time to be set to any values.

Four ranges: 10.00 to 99.99 V/s, 100.0 to 999.9 V/s, 1.000 to 9.999 kV/s, 10.00 to 99.99 kV/s

The variable slew rate function is available for current source as well on the 6254. (The 6253 is supported from software revision B00 or later.)

Suspend function

The output OFF state can be selected from three states: STBY (output relay OFF), HiZ (output relay ON and high resistance state), and LoZ (output relay ON and low resistance state). 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.

Output OFF status Output relay Output status Current limit setting value
LoZ ON Vsus, low resistance

VS: Setting current limit (IL)

IS: 3000 digits in the setting current range (10000 digits for the 3 μA range)

HiZ ON Vsus, high resistanc

6253: 100 nA

6254: 3 μA


High-speed response

The output response can be switched between Fast and Slow. When the output response is set to Fast, the 6253/6254 starts up faster than the former models.

HI/LO limit separate setting

6253 HI/LO Limit Separate Setting

In voltage or current source, the HI/LO limit settings are very important. The 6253/6254 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.


【Display screen】
Source voltage (VS), source current (IS),
limit values (HL/LL), measured voltage (VM)
and measurement current (IM) are displayed.
Voltage and current can be measured simultaneously.
【Time setting screen】
Time settings are important for pulse or
sweep source. The time setting screen on the
6253/6254 allows you to make these settings easier
than the former models.
【Graph display screen】
You can easily view measurement results
from the graphically displayed measurement
memory data.
There are two display options: voltage and
current value display and display of the number of memories and measured values.
