Agilent 6014a Power Supply Paper Capacitor
Introduction
The Agilent DSO6014A oscilloscope is a high-performance instrument used for various applications in the fields of electronics, engineering, and research. However, like any electronic device, it can be prone to failures, especially if not properly maintained. One common issue that can arise in the power supply of the Agilent 6014A is the failure of the paper capacitor. In this article, we will discuss the replacement of the paper capacitor in the power supply of the Agilent 6014A oscilloscope.
Understanding the Problem
The paper capacitor in the power supply of the Agilent 6014A oscilloscope is a critical component that helps to filter and regulate the power supply. However, over time, the paper capacitor can degrade and eventually fail, leading to a range of problems, including:
- Power supply instability: A failed paper capacitor can cause the power supply to become unstable, leading to fluctuations in the voltage and current output.
- Oscilloscope malfunction: A faulty power supply can cause the oscilloscope to malfunction, leading to inaccurate readings and potentially damaging the instrument.
- Fire risk: In extreme cases, a failed paper capacitor can cause a fire, especially if the capacitor is located in a confined space.
Identifying the Paper Capacitor
The paper capacitor in the power supply of the Agilent 6014A oscilloscope is typically located in a hard-to-reach area, making it difficult to identify. However, there are a few ways to determine if the paper capacitor has failed:
- Visual inspection: Look for signs of physical damage, such as cracks, burns, or discoloration, on the capacitor.
- Multimeter test: Use a multimeter to measure the capacitance and resistance of the capacitor. A failed capacitor will typically show a low or zero capacitance reading.
- Power supply test: Use a power supply test kit to measure the output voltage and current of the power supply. A failed capacitor will typically cause the power supply to become unstable.
Replacing the Paper Capacitor
Replacing the paper capacitor in the power supply of the Agilent 6014A oscilloscope requires some technical expertise and specialized tools. Here are the steps to follow:

Before starting the repair, make sure to disconnect the power supply from the oscilloscope. This will prevent any accidental electrical shocks or damage to the instrument.
Step 2: Locate the Paper Capacitor
Use a multimeter or a capacitor tester to locate the paper capacitor in the power supply. Once located, take note of the capacitor's part number and value.
Step 3: Remove the Old Capacitor
Use a screwdriver or a wrench to remove the old capacitor from the power supply. Be careful not to touch any of the electrical components or wires.
Step 4: Install the New Capacitor
Install the new capacitor in the power supply, making sure to connect it to the correct terminals. Use a multimeter or a capacitor tester to verify that the new capacitor is functioning correctly.
Step 5: Reassemble the Power Supply
Reassemble the power supply, making sure to reconnect all the electrical components and wires.
Step 6: Test the Power Supply
Use a power supply test kit to test the output voltage and current of the power supply. Make sure that the power supply is functioning correctly and that the new capacitor is not causing any issues.
