ADCMT DC Voltage Current Source/Monitor 6241A / 6242

High-performance DC voltage current source/monitor capable of pulse source/measurement with a minimum pulse width of 50 μs

The 6241A/6242 is a DC voltage and current source/ monitor capable of 4½-digit generation and 5½-digit measurement with high accuracy of ±0.02 %.
The instrument has two slope linear sweep, linear sweep, fixed sweep and random sweep functions, and is also capable of pulse measurement with a minimum pulse width of 50 μs and low voltage/current measurement with a resolution of 1μ V/100 pA. Thus, it can be used for a wide range of applications for evaluation in R&D of semiconductors and other electronic components, or for characteristic tests in a production line.
The sink-enabled bipolar output, the individual HI/LO limiter function and the suspend function are effective in evaluation of batteries and power ICs.

Features

 

Source and measurement function

Voltage/current source and voltage/current/resistance measurement can be selected by specifying the source and measurement functions.

 

Voltage/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 (user programmable sweep), two 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.

 

Individual settings of HI/LO limiters

In voltage/current source, the HI/LO limiter settings are very important. The 6241A/6242 has a function that can set the HI and LO limiters individually. 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 such as LDs that are used at a constant current and do not tolerate reverse voltage application.

 

Suspend function

The 6241A/6242 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 action, which reduces deterioration of the throughput due to relay operation time and improves the life span of the relay. In addition, the setting of a suspend voltage (voltage in HiZ and LoZ status) prevents transient current sink that occurs at a connection of a voltage output device such as a battery.

 

Sample hold measurement

Sample hold measurement is available in the pulse mode and the pulse sweep mode. Measurement holds an input signal immediately before pulse falling edge, and A/D conversion is implemented for integration time of 100 μs. In this case, the setting measurement delay time is ignored.
