N6705C Four-Channel Configuration

This setup is recommended for multi-event synchronization testing for both signaling and normal operation. Normal operation is defined as the operation upon successful connection.

This four-channel configuration requires the following setup:

  • Channel 1: Connect DUT
  • Channel 2: Connect X8712AD RF event detector
  • Channel 3 and 4: Custom wiring and/or custom sensors with voltage or current response to synchronize the events.

Channel 1 is fixed as 'Battery Emulator' module and is used to power up the DUT and monitor the total current drain.
Channel 2 may use 'Power Detector' module with the X8712AD RF event detector connected to capture the RF signal transmitted or received by the DUT.


  1. Follow the instructions from step 1 to 7 in the Connect an Over-the-Air DUT in Self Advertising or Test Mode section.

  2. There are two options to set up the connection in Channel 3 and 4:

    1. Connect the 2-wire cable to the device subcircuit power lines for events synchronization.

    2. Connect to the voltage or current responding sensors without having physical connection to the DUT.

  3. If you are using a voltage based sensor in Channel 3 and a current based sensor in Channel 4 to synchronize the events, connect your voltage-based sensor to Channel 3 using V+ and V- 2-wire configuration to the output binding post terminals. Do the same to connect the current-based sensor to Channel 4.

You have completed the hardware setup based on this example.
