  • Channel 2: 0 to 25 V, 0 to 1 A
  • Channel 3: 0 to -25 V (negative output), 0 to 1 A
• Load and Line Regulation:
  • Voltage: <0.01% + 2mV
  • Current: <0.01% + 250µA
• Ripple & Noise (20 Hz to 20 MHz):
  • Voltage RMS: 0.35 mV
  • Peak-to-Peak: 3 mV
• Programming Accuracy (at 25°C ±5°C):
  • Voltage: 0.05% + 10 mV
  • Current: 0.1% + 10 mA

1. Initial Setup:

   • Ensure the power supply is turned off before making any connections.
   • Connect the power cord to the power supply and plug it into an appropriate AC outlet.

2. Connecting to a Circuit:

   • Use appropriate cables to connect the output terminals to your circuit.
   • Ensure that the polarity matches your circuit requirements.

3. Setting Output Values:

   • Power on the E3631A.
   • Select the desired channel using the front panel buttons.
   • Adjust the voltage and current settings using the knobs or keypad.

4. Monitoring Outputs:

   • The LCD display shows the set values and actual output for voltage and current.
   • Monitor these values to ensure they match your circuit requirements.

• Safety: Always follow standard safety procedures when working with electrical equipment.
• Load Matching: Ensure that the power supply's maximum output ratings are not exceeded by the connected load.
• Cooling: Allow sufficient ventilation around the power supply to prevent overheating.
• Grounding: Properly ground the power supply to avoid electrical hazards.

• No Output Voltage:

  • Check if the power supply is turned on and properly connected to the AC source.
  • Verify that the output terminals are securely connected to your circuit.
  • Ensure that the output settings are correctly adjusted for your needs.

• Inaccurate Output Voltage or Current:

  • Calibrate the power supply regularly to maintain accuracy.
  • Check for any load variations or circuit issues that may affect the readings.

• If the power supply does not turn on, check the fuse and replace it if necessary.
• For output stability issues, verify that the power supply is not being overloaded or overheated.
• If the problem persists, refer to the Agilent E3631A service manual or contact technical support.

Q: Can I use all three outputs simultaneously? A: Yes, the E3631A is designed to provide three independent outputs that can be used at the same time.

Q: How do I set the power supply to output a negative voltage? A: Use Channel 3, which is specifically designed to provide a negative output voltage up to -25V.

Q: What is the warranty period for the Agilent E3631A? A: The standard warranty period is typically one year, but it may vary by region. Check with Agilent for specific warranty information.
