RIGOL RPL1116 Logic Analyzer Probe User Manual

1. Introduction

The RIGOL RPL1116 is a 16-channel logic analyzer probe specifically designed for use with RIGOL DS1000Z series oscilloscopes. It enables real-time multi-channel digital signal capture and analysis, providing high sensitivity and accuracy for effective detection and diagnostics in complex logic systems. This manual provides instructions for the proper setup, operation, and maintenance of your RPL1116 logic analyzer probe.

3. Setup Instructions

Follow these steps to properly connect and prepare your RPL1116 logic analyzer probe for use.

1. Connect RPL1116 to the Oscilloscope

   Connect the active logic probe head to the main cable input. Then, connect the main cable output to the digital signal input terminal on the front panel of your RIGOL DS1000Z series oscilloscope.

2. Connect Signals Under Test to RPL1116

   You can connect any number (up to 16) of the signals under test to the RPL1116 according to your test requirements. Ensure that the amplitude of the input signal does not exceed the maximum working voltage range of the probe. The RPL1116 provides two connection methods for convenient and flexible detection:

   • Method 1: Direct Lead Connection
     Connect the signals under test directly through the probe leads. You can easily identify the corresponding channel of each signal by the channel label on the probe leads and the color information on the probe head.

     Note:

     Crosstalk or ground bounce may occur if channels share a single ground lead. It is recommended to add one ground wire to the signal lines of each channel and twist them together for better signal integrity.

   • Method 2: Grabber Connection
     Building on Method 1, you can attach a grabber to each lead and then connect the grabber to the device under test. This provides a more secure and flexible connection to test points.

4. Operating Instructions

Once the probe is physically connected, configure the oscilloscope for proper signal acquisition.

3. Set the Probe Parameters

   Press the LA button on the front panel of the oscilloscope to enter the probe setting menu. Within this menu, you can view and adjust the following parameters:

   • Threshold Level: The threshold levels for channels D0-D7 and D8-D15 can be adjusted independently.
   • Waveform Size: Applicable to all channels. Note that the 'L' (Large) waveform size option is only available when the number of active channels is no more than 8.
   • Channel Label: Assign labels to individual channels for easier identification.
   • Probe Calibration: Access the calibration function.

   Note:

   When connecting the probe to the oscilloscope for the first time, or if the ambient temperature changes by more than 5 degrees Celsius, it is recommended to calibrate the probe zero using the auto-calibration function in the LA menu. Ensure all signals are disconnected from the RPL1116 input terminal during calibration.

4. Function Inspection

   After completing the above operations, the signal under test should be displayed on the corresponding digital channel on the oscilloscope screen. If no signal is displayed:

   • Adjust the oscilloscope to select proper general settings, such as the trigger mode and timebase.
   • If the problem persists, recheck all electrical connections and parameter settings.
   • Try using other probes (e.g., an analog probe) to verify the signal state at the test point.

5. Maintenance

• Cleaning: Use a soft, dry cloth to clean the probe and its accessories. Do not use abrasive cleaners or solvents.
• Storage: Store the probe in a clean, dry environment within the specified storage temperature range (-20°C to 60°C, 0~90%RH). Protect it from dust, moisture, and extreme temperatures.
• Handling: Handle the probe and its leads with care to avoid physical damage. Do not bend cables sharply or apply excessive force to connectors.

6. Troubleshooting

If you encounter issues while using your RPL1116 probe, refer to the following common problems and solutions:

• No Signal Displayed on Oscilloscope:
  • Verify that the RPL1116 main cable is securely connected to both the active logic head and the oscilloscope's digital input.
  • Ensure the test leads and grabbers are properly connected to the signals under test.
  • Check the oscilloscope's settings: adjust trigger mode, timebase, and ensure the digital channels are enabled and properly configured.
  • Perform probe calibration as described in the operating instructions.
  • Test the signal source with a known working probe (e.g., an analog probe) to confirm the signal is present and valid.
• Incorrect or Distorted Waveforms:
  • Ensure proper grounding. Add ground wires to each signal line and twist them to reduce crosstalk and ground bounce.
  • Verify that the input signal amplitude is within the probe's maximum working voltage range (±40V).
  • Check the threshold level settings in the oscilloscope's LA menu.
  • Recalibrate the probe.
• Probe Not Recognized by Oscilloscope:
  • Ensure the oscilloscope is a compatible RIGOL DS1000Z series model.
  • Check the physical connection of the main cable to the oscilloscope's digital input port.
  • Restart the oscilloscope.
