Advantest R6244 DC voltage/current source/monitor

Advantest R6244 DC voltage/current source/monitor

DC voltage/current source monitor ideal for electronic circuit/component evaluation by flexible source and measurement 

Wide ranging source/measurement 6243 Voltage: 0 to ±110V Current: 0 to ±2A 6244 Voltage: 0 to ±20V Current: 0 to ±10A 

5½-digit display with 1μV/100pA (6243), 1μV/1nA (6244) resolution in measurement 

Pulse measurement with a minimum pulse width of 1ms 

Sink-enabled bipolar output

The 6243/6244 provides high accuracy with 4½-digit source resolution and 5½-digit measurement resolution, a variety of sweep functions, and a pulse measuring function with a minimum pulse width of 1ms. Thus, it can be used for a wide range of applications as a power source for evaluation in research and development of semiconductors and other electronic components or for characteristic test systems in a production line

For Characteristic Test for Transistor and FET

Synchronized operation of the two units of the 6243/6244 allows characteristic test of a transistor or FET. Id and Ig can be measured simultaneously, as controlling the source timings of drain voltage and gate voltage to protect a device from stress. 

● Linear, log and random sweep functions 

● Pulse measurement with a minimum pulse of 1ms 

● M e a s u r e m e n t d e l ay function for measurement timing control 

● Source delay function for source timing control

For Battery Charge/Discharge Test

The 6243/6244 is available for battery charge and discharge test at constant current (CC) or constant voltage (CV) by DC or pulse application. In a pulse charge and discharge test, measurement must be done at the time of and after the pulse application. Using two units will allow measurement at the two points above and increase the current capacity up to 20A. 

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

● 20A (6244) and 4A (6243) by two-unit parallel operation 

● Measurement at pulse HI/LO points 

● Selectable from voltage measurement or current measurement

Low Noise

The performance of a power supply basically depends on the accuracy of source voltage/current and the quantity of noise superimposed to them. The 6243/6244 adopts a minimum noise design effective for input signals of a DC amplifier and other cases susceptible to power noise. This model is the perfect power supply for linear ICs, optical devices or mobile communication amplifiers.

For Temperature Dependence Test of Diode VF

In a characteristic test on a power diode, applying pulse current is effective for avoiding the influence of self-heating. The current pulse sweep function and pulse-synchronous voltage measurement ensure accurate VF characteristic test at large current.

For DC/DC Converter Characteristic Test

The following functions are effective for DC/DC converter characteristic test: 

● Parallel measurement of input current and output voltage/current by using two units 

● Electronic load capable of operation down to 0V (General electronic loads do not operate at 0.8V or less.) 

● Large output current up to 10A (7V) (6244)
