This section lists the steps to create and send a DAC pattern from the TSW14J5x board.

1. Click on the HSDC Pro DAC tab. Figure 7-1 shows a brief description of the DAC tab.

3. How to create and send a sinusoid is outlined in the steps that follow:
   1. Select AFE79xx_2x2TX_44210 in the device-specific initialization option. Click Yes if prompted to download the firmware (FW). The default option is to run the board in the transceiver mode of operation, which enables simultaneous operation of the TX and the RX and FBRX. The FW used in transceiver mode has the letters XCVR in its name.
   2. Enter 491.52 M as the data rate and 0.9 for a scaling factor.
   3. Create a sinusoid by entering the frequency in the Tone Generator section of the HSDC Pro window.
   4. Press Send to transmit the DAC pattern to the TRF1208-AFE7950-EVM. Figure 7-3 shows the resulting message with the lane rate and reference clock expected in the FPGA. Click OK.

Figure 7-4 shows an example setup with a 100-MHz sinusoid.

Alternately, a pattern file (for example, LTE) can be loaded and sent using the Load External Pattern File button.

The DAC setup is now complete.
