Key Components:

• MS-156 Male Plug: A specialized connector often used in test equipment and certain RF applications.
• RP-SMA Male Plug: A Reverse Polarity SMA connector, commonly found on Wi-Fi antennas and other RF devices.
• RG174 Coaxial Cable: A thin, flexible coaxial cable suitable for short-distance signal transmission.

Setup Instructions

Follow these steps to properly connect your MS-156 / MS156 cable:

1. Identify Connectors: Locate the MS-156 male plug and the RP-SMA male plug on the cable. Ensure they match the corresponding ports on your devices.
2. Connect MS-156 End: Carefully align the MS-156 male plug with the MS-156 port on your test equipment, oscilloscope, or RF amplifier. Push firmly until it clicks or seats securely.
3. Connect RP-SMA End: Align the RP-SMA male plug with the RP-SMA port on your other device (e.g., antenna, mixer). Gently screw the connector clockwise until it is finger-tight. Do not overtighten, as this can damage the connector or the device port.
4. Verify Connection: Ensure both ends are securely connected and there is no loose play. A proper connection is crucial for optimal signal integrity.

Important: Always power off devices before connecting or disconnecting cables to prevent potential damage.

Operating Guidelines

Once connected, the Amphenol MS-156 / MS156 cable facilitates signal transmission between compatible devices. Its primary applications include:

• RF Testing: Use the cable to connect RF test probes, signal generators, spectrum analyzers, or oscilloscopes for various radio frequency measurements and diagnostics.
• Digital Audio Transmission: While primarily an RF cable, RG174 can be used for certain digital audio applications where coaxial connectivity is required, such as connecting specific audio components.
• Antenna Connections: The RP-SMA end is commonly used for connecting external antennas to wireless devices, routers, or other equipment requiring RP-SMA interface.

Ensure that the impedance of the cable (typically 50 Ohm for RG174) matches the impedance requirements of your connected devices for optimal performance and minimal signal loss.

Care and Maintenance

Proper care will extend the life and performance of your cable:

• Handling: Avoid sharp bends, kinks, or excessive pulling on the cable, especially near the connectors, as this can damage the internal conductors.
• Cleaning: If connectors become dirty, gently wipe them with a clean, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the cable loosely coiled in a dry, cool place away from direct sunlight and extreme temperatures. Avoid tangling with other cables.
• Inspection: Periodically inspect the cable and connectors for any signs of wear, damage, or corrosion. Replace the cable if any damage is observed.

Troubleshooting

If you experience issues with your cable, consider the following common troubleshooting steps:

• No Signal or Weak Signal:
  • Ensure both ends of the cable are securely connected to the correct ports.
  • Check if the connectors are fully seated and tightened (RP-SMA).
  • Inspect the cable for visible damage (kinks, cuts, frayed shielding).
  • Verify that the connected devices are powered on and functioning correctly.
  • Confirm that the impedance of the cable matches the device requirements.
• Intermittent Connection:
  • This often indicates a loose connection. Re-seat and re-tighten connectors.
  • Check for internal damage to the cable that might not be visible externally.
• Physical Damage to Connectors:
  • If pins are bent or housing is cracked, the cable may need replacement.
  • Avoid forcing connectors into incompatible ports.

If problems persist after following these steps, contact customer support or consult a qualified technician.
