IWR1443BOOST: CW output

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: IWR1642BOOST, IWR1443

Hi Experts,
I would like CW output for Tx with IWR1443BOOST and IWR1642BOOST.
Could you please let me know how I can set the parameters for OOB.

For example, it is 78.5GHz continuous output with 100% duty.

Thank you very much for your kind support.

  • Hello Hitoshi,

    You would use the mmWave DataCapture demo described in section 3.4  for mmwave SDK 1.05 (it is being updated soon to 1.1)

    When you program for Data capture for either 14xx or 16xx, there is an MSS UART that is opened on the PC over USB. 3.4.2 for IWR1443

    You would modify the default configuration below modified from capture_demo_script_lvds_cont_mode.txt)

    # continuous mode -  dfeDataOutputMode 2

    # channel cfg - Rx mask all, Txmask Tx1;Tx2, 0 - channelCfg 15 3 0

    #  DFEoutput mode 16bits, ADC&DFE complex 1x - adcCfg 2 1

    #  adcbufCfg - 0 0  (depends on device 0-1443; 1 1642) 1

    # contModecfg - start freq 78.5 ;  Tx output power backoff 0; Txphase shift 0; digOutksps 5000; hpf1 0; hpf2 0; rxgain 42; tx enable (1 or 3); adcsamples 1024

    # setHSI LVDS (CSI - diff format 1443) 1443; 1642

    flushCfg

    dfeDataOutputMode 2

    channelCfg 15 1 0

    adcCfg 2 1

    adcbufCfg 0 0 0 1

    lowPower 0 0

    contModeCfg 78.5 0 0 5000 0 0 42 1 1024

    setHSI LVDS

    sensorStart

    Note: there are some specific differences for 1443, 1642, this is initially for 1443.

  • Hi Joe,
    Will test it.
    Thank you.
