6181C

The 6181C is a constant current source. It is an electronic test equipment. It has such circuit that is capable to deliver and absorb electrical current. This current is independent of the voltages across the terminal. The 6181C comes with the special guard supply. It is used to prevent to internal leakage currents. These leakage currents can cause degradation in regulation characteristics. The positive output voltage is kept equal to the guard voltage. It helps to isolate volt meter at the front panel from the supply. It helps to mitigate degradation at the output.

The 6181C current source is transistorized completely. It makes it workable for bench or rack operation. It has voltage and current control options at front panel. The voltage control is used to limit output voltage in constant current mode. The current control is used to limit output current in voltage limit source mode of supply. The 6181C also incorporates a single meter to measure voltage and current. The front panel has a meter switch to select between voltage and current. It has the capability to measure output current in three different ranges. The output voltage is measured in only one range.

The 6181C comes with remote programming capability. It is accomplished by use of external voltage source or resistor. The output current can be programmed in the up and down direction with the help of this method. The user can also monitor the output voltage of 6181C from an external source. It makes use of an accurate differential meter or voltmeter. It has the full-scale current rating of 0 to 250 mA. The voltage rating for 6181C is 0 to 100 volts. It also has the capability to measure dynamic impedance and voltage breakdown.
