Advantest R6243/6244 DC Voltage Current Source/Monitor

INTRODUCTION

R6243/6244 is a DC voltage and current source/monitor with wide ranges of generation and measurement. R6243: Voltage = 0 to ±110 V, current = 0 to ±2 A R6244: Voltage = 0 to ±20 V, current = 0 to ±10 A The R6243/6244 provide high accuracy with a setting resolution of 4 1/2 digits and a measuring resolution of 5 1/2 digits, a variety of sweep functions and a pulse measuring function for the minimum pulse width of 1 ms. The R6243/6244 can be used a power supply in many applications such as for test system, for evaluations of semiconductors and other electronic parts in R&D, etc.,

● Linear, logarithmic, and random sweep functions for characteristics tests 

● Limiter (compliance), oscillation, overload, and overheat detection functions 

● Synchronous operation function by combining two R6243/6244s or more 

● GPIB for automatic measuring system

Source Modes

The R6243/6244 has four source modes – DC, pulse, DC sweep, and pulse sweep. The sweep can be selected three types of mode such as linear, log, and random (arbitrary waveform generation by user programming).

Source/Measurement Timing

In pulse and sweep modes, the source and measurement timings are synchronous and the measurement is permitted after a specified time from trigger. Setting the measure delay (Td) permits a measurement after a specified time from the end of the pulse such as stress tests.

Range Switching without Discontinuity

The voltage and current source ranges can be changed without lowering the output to zero from the level before switching. This allows no discontinuity at the output and reduces adverse effects on devices with hysteresis or high dielectric constant.

Low Noise

The basic requirements for power supply performance are accuracy of the voltage/current source and measuring against the noise added on the output voltage/current. The R6243/6244 has a minimum-noise design effective for the case susceptible to power noise and input signals of DC amplifier. The R6243/6244 is the perfect power supply for a linear IC, optical device, or mobile communication amplifier.

For a transistor, FET characteristics test

In a transistor or FET characteristics test, two units of R6243/6244 can be used for simultaneous measurement. The R6243/6244 controls the generation timings of the drain and gate voltage to protect a device from stress. It can measure Id and Ig simultaneously. 

● Linear, log, and random sweep functions 

● Pulse measurement (minimum pulse width: 1 ms) 

● Measure delay function for measurement timing control 

● Source delay function for generation timing control

For a battery charge and discharge test

The R6243/6244 is available for a battery charge and discharge test at constant current (CC) or constant voltage (CV) by DC or pulse applications. For a pulse charge and discharge test, measurement is necessary while and after the pulse application. Two units of R6243/6244 can be used in parallel operation for measurement at the above two points and to increase the current capacity up to 20 A. 

● Source sink current up to ±20 A (7 V) 

● 20 A (R6244) and 4 A (R6243) by two units in parallel operation 

● Measurement at pulse HI/LO point 

● Selection of voltage or current measurement
