Source and measurement function
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 four sweep types: fixed sweep, linear sweep, random sweep (arbitrary waveform generation by user programming), 2-slope linear sweep (linear sweep with step value switching).
The minimum pulse width is 50 μs. The minimum cycle is 2 ms, or 500 μs without measurement.
HI/LO Limiter separate setting
In voltage or current source, the HI/LO limiter settings are very important. The 6240B allows separate setting of HI and LO limiters. Furthermore, for the voltage-limiter, both HI and LO limiters can be set homo-polar. This prevents a capacitor or a battery from being over-discharged. Also, it is suitable for evaluating devices that are used at a constant current and do not tolerate reverse voltage application.
The 6240B 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 can omit unnecessary relay ON/OFF operations.
Consequently it prevents throughput reduction due to relay operating time, extends relay lifetime and increases 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.
Low-resistance measurement with pulse current unaffected by heat
The 6240B achieves low-resistance measurement without being affected by self-heating of DUTs by using pulse current application, bringing more precise measured values with little errors.
