Version:
    Last Modified: March 25, 2021

    Before you begin this procedure, create a PXIe-657x interface using the Digital Pattern Editor and configure the interface using the Semiconductor Device Control Add-On.

    Ensure that you open your Semiconductor Device Control Add-On project in a large panel before configuring interfaces and functions.

    Complete the following steps to configure a dEVM RFFE custom function for a PXIe-657x interface.

    1. Click Conf I/F to open the Hardware Configuration tab of the large panel.
    2. In the configuration section of the Hardware Configuration tab, select the PXIe-657x interface that you want to add a custom function to and click Add Function.
    3. Select Custom from the Function Type list, and select dEVM_RFFE from the list of custom functions. Enter the name of the custom function, and click Add.
    4. Select the new custom function in the list to display the configuration options.
    5. Configure the pin settings for the custom function.
      1. Select the pin group from the Pin Group drop-down menu.
      2. Select the clock pin from the Clock Pin drop-down menu.
      3. Select the data pin from the Data Pin drop-down menu.
      4. Select the bus number using the Bus drop-down menu.
    6. Configure the pattern settings for the custom function.
      1. Select the timing file from the Timing File Name drop-down menu to satisfy clock polarity and phase requirements for the custom function.
      2. Select the voltage level file from the Levels File Name drop-down menu.
    7. Configure the RFFE settings for the custom function.
      1. Enter the clock frequency in the Clock Rate (KHz) input.
      2. Enter the 4-bit slave address of the RFFE device in the Slave Address input.
      3. Select the command type of register transactions from the R/W Command drop-down menu.
    8. Configure the time domain reflectometry (TDR) settings for the custom function.

      Refer to the NI Digital Pattern Help for more information about configurin TDR.

      1. Enter the TDR factor to be applied to the data pin in the Data Pin TDR(ns) input.
      2. Enter the TDR factor to be applied to the clock pin in the Clock Pin TDR(ns) input.
    9. Configure the time settings for the custom function.

      Script files containing these commands override those entered in the Hardware Configuration tab.

      1. Enter the time delay after the on-command is sent to the DUT in the t1(us) input.
      2. Enter the time delay after the off-command sequence is sent to the DUT in the t2(us) input.
      3. Enter the time delay between when the RF measurements end and the DUT is turned off in the t3(us) input.
      4. Enter the time during which the RF stimulus signal is applied from the vector signal generator, and measurements are made by the vector signal analyzer in the tRF(us) input.
    10. Configure the trigger settings for the custom function.
      1. Select the trigger type from the Trigger Type drop-down menu.
      2. If using a DIO trigger, select a trigger pin from the pin map for the trigger line from the Trigger Pin drop-down menu.
      3. Enter the pulse width in nanoseconds in the Pulse Width(ns) input.
      4. If using a backplane trigger, select the event used to trigger from the Trigger Event drop-down menu.
