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 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 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

6253 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.

Display

Time settings are important for pulse or
sweep source. The time setting screen on the
6253 allows you to make these settings easier
than the former models.
【Graph display screen】
