DC Voltage Current Source Monitor
6253
- Source and measurement range
Voltage: 0 to ±110 V, Current: 0 to ±2 A - 5½ source digits and 6½ measurement digits
(measurement resolution: 100 nV/1 pA) - High-speed pulse source with the minimum pulse width of 25 μs
- Variable slew rate function: 10.0 V/s to 99.9 kV/s
- Variable integration function
- Sink-enabled bipolar output
- Voltage and current parallel measurement by twin A/D converters
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 functions
Voltage/current source and voltage/current/resistance measurement can be selected by specifying the source and measurement functions.
The 6253 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.
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). 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 | 100 nA |
| STBY | OFF | Open | － |
High-speed response
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.
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.

Applications
DC/DC converter evaluation
The following functions are effective for DC/DC converter characteristic test.
- The input current and the output voltage or current can be measured simultaneously by synchronizing two units of the 6253.
- ±Source and ±sink by bipolar output
The 6253 allows 0 V sink which is unavailable by normal electronic load.
Protection of overshoot at capacitive load
When a capacitive load is connected, overshoot occurs at the rising or falling edge and the DUT may be damaged or the output becomes unstable. Using the variable slew rate (SR) function of the 6253 will alleviate voltage waveforms and protect overshoot.
Diode VF temperature dependence evaluation
Pulse current application is effective for power diode characteristic test to avoid the influence of self-heating. By using the current pulse sweep function and voltage measurement in synchronization with pulses, precise VF characteristic test is available even with large current.
Average current measurement 【Variable Integration Function】
The 6253 allows you to set the integration time arbitrarily from 100 μs to 1000 ms. This makes it measure easily the average current consumption of mobile phones and LCDs.
As any integration time of the AD converter itself can be set and analog integration is adopted, there are no omissions in waveforms differently from digital integration, resulting in precise average measurement.
