3.4 Hardware Configuration

Follow this procedure to setup the boards and equipment.

  • Connect TSW14J56
    • Plug in 5V power cable to TSW14J56
    • Set voltage to 5.0V (or up to 5.5V)
    • Make sure current limit is set for 3.5A or higher
    • Connect PC to EVM through USB connection
    • Make sure power switch on the board is on

  • Plug in FMC Interface Board to TSW14J56

    • Plug in external 491.52MHz Wenzel Oscillator (or equivalent) to J3 CLKINP SMA connector
    • Plug in cable from USB2ANY to connector labelled “USB2ANY”
    • Plug in 5V power cable; set voltage to 5.2V (make sure current limit is 5A or greater)
    • Plug PC to FMC Interface Board through USB connector
    • Verify jumpers placed at J6 location K, L, N
    • Jumper J6 location M selects programming to LMK or LMX device. Initially, verify that jumper is not placed.

  • Plug in TIDA-010260 Reference Design to the FMC Interface Board.

    • Connect fan power to “Fan Power” connector on the interface board
    • Make sure additional cooling fans are on and blowing over the AFE7950-SP board
    • Connect TXA output to Spectrum Analyzer
    • Connect Signal Generator through BPF to RXA input

  • Spectrum Analyzer Setup

    • Set center frequency to: 2210MHz
    • Set frequency span to: 5MHz
    • Ref Level: 8.8dBm
    • RBW: 3kHz
    • VBW: 3kHz
    • Attn: 28dB
