Keysight 6633B DC Power Supply

The Keysight 6633B Power Supply is an economic and easy-to-use unit. While using this model, the user should take into account that if more than one meter is utilized or if a meter and an oscilloscope are used, they can be connected to the terminals with a pair it leads to avoid impacts of mutual coupling. For constant voltage DC testing, connect only to +S and -S, since the unit regulates the output voltage that appears between S+ and S-, and not between output terminals (+) Also (-). Coaxial cables or a protected two-wire cable can be utilized to eliminate noise in the test cables.

The power-on self-test sequence tests the majority of the digital and DAC circuits. If the supply fails the self-test, the display "ERR" annunciator will come on. Afterwards, the user could inquire the unit to find out what the error(s) are. When an error is detected, the output is not disabled, so the user can still try to program the supply to help troubleshoot the unit.

In the 6633B, the CV/CC annunciators are especially supportive when troubleshooting a unit with no output. If the unit does not need output voltage or current and one of the annunciators is part of the problem in the control circuit associated with that annunciator, this would be useful. In case the voltage and current are programmed for positive values, there might not be output voltage and the CV annunciator is on. This demonstrates that the issue will likely be in the Voltage enhancer circuit.
