Page Agilent Basic Programs Programmable Instruments commands available to program the power supply. This program sets the output voltages and currents for 30! This program also shows how to use "state storage" to store the instrument configuration in memory.
This program uses low-level SCPI commands to program the 30! Page ' also shows the use of a trigger received over the GPIB interface to ' initiate a single trigger. This program uses the status registers to generate an 30! Set the power supply to an output for three outputs ! Page Chapter 7 Tutorial Tutorial Page Tutorial The Agilent EA is a high performance instrument capable of delivering clean dc power. But to take full advantage of the performance characteristics designed into the power supply, certain basic precautions must be observed when connecting it for use on the lab bench or as a controlled power supply.
Page Overview Of Agilent EA Operation To keep the voltage across the series resistance low, some supplies use preregulation before the rectifier bridge. Figure shows a controlled transformer tap as used in the Agilent EA.
This is one of several techniques using semiconductors for preregulation to reduce the power dissipated across the series element. Page The Agilent EA contains three linear regulated power supplies. Each is controlled by a control circuit that provides voltages to program the outputs. Each supply sends back to the control circuit voltages representing outputs at the terminals. Under certain fault conditions, the power supply can not operate in either CV or CC mode and becomes unregulated.
The operating point of one supply will be either above or below the line R. This line represents a load where the output voltage and the output current are equal to the voltage and current setting.
Page Unregulated State Normal mode voltage noise is in the form of ripple related to the line frequency plus some random noise. Both of these are of very low value in the Agilent EA. Careful lead layout and keeping the power supply circuitry away from power devices and other noise sources will keep these values low. Simplified Diagram of Common Mode and Normal Mode Sources of Noise When the load changes very rapidly, as when a relay contact is closed, the inductance in the hook up wire and in the power supply output will cause a spike to appear at the load.
Any output terminal may be grounded, or an external voltage source may be connected between any terminal output and ground. Large load capacitors may cause ringing in the power supply's transient response. It is possible that certain combinations of load capacitance, equivalent series resistance, and load lead inductance will result in instability.
Page Chapter 7 Tutorial Connecting the Load Reverse Current Loading An active load connected to the supply may actually deliver a reverse current to the supply during a portion of its operating cycle. An external source can not be allowed to pump current into the supply without risking loss of regulation and possible damage. Page Remote Programming Chapter 7 Tutorial Remote Programming Remote Programming During remote programming a constant-voltage regulated power supply is called upon to change its output voltage rapidly.
The most important factor limiting the speed of output voltage change is the output capacitor and load resistor. Figure Page Chapter 7 Tutorial Remote Programming If no load resistor is attached to the power supply output terminal, then the output voltage will rise linearly at a rate of C when programmed upward, and , the shortest possible up-programming time.
Speed of Response -Programming Down Figure shows that when the power supply is programmed down, the regulator senses that the output voltage is higher than desired and turns off the series transistors entirely. Page Reliability A fan internal to the Agilent EA is essential to keep internal temperatures low.

Supplemental characteristics, which are not warranted but are descriptions of performance determined either by design or testing. The service guide contains procedures for verifying the performance specifications. Output Voltage Overshoot During turn-on or turn-off of ac power, output plus overshoot will not exceed 1 V if the output control is set to less than 1 V.
