Use the following list to setup the dual DAC one data bank per channel:
- Change the frequency of the signal generator connected to EXT_DACCLK (SMA J2) to
1.6 GHz. Change the frequency of the signal generator connected to LMK IN (SMA
J25) to 400 MHz.
- Press the DAC RESET switch.
- Click on the DAC12DL3200EVM Low
Level View tab.
- Click on the “File” icon and
navigate to “EXT_CLK_Mode1_NRZ_Dual_DAC.cfg” and click on “OK” to load the LMK
and DAC registers.
This
configuration file will setup the DAC to operate in dual channel mode, 1
bank of LVDS data only for each DAC, with outputs available on CHA and
CHB.
- In the HSDC Pro GUI, in the
device drop-down menu, select "DAC12DL3200_MODE1_12b_sync_istrb”. If the
firmware is already loaded, skip the next step.
- When prompted, click Yes
to update the firmware. After the firmware is downloaded, do the DxSTR register
write mentioned in the DxSTRB Timing Adjustment section.
- Enter 1.6 GHz for the Data
Rate.
- In the I/Q Multitone
Generator window in the lower left of the GUI, enter the following
parameters: # of tones "1", tone center "500 MHz" then click "Create
Tones".
- Click on "Send" in the upper left of the main GUI page to send the test tone to
the DAC EVM. There should now be a 1 GHz output tone on CHA and CHB SMA
connectors J1 and J4.
