3.11 DxSTRB Timing Adjustment
1. By default, the current firmware used by HSDC Pro sends a square wave instead of a pulse for the DxSTR
signals. The DAC requires a pulse for DxSTR that needs to be a width that is a multiple of 4 LVDS clock
cycles. To correct for this, do the following in HSDC Pro GUI:
a. Click on the
Instrument Options tab located in the top left of the DAC main page.
b. Click on IO Delay .

3-9 . Click the Write Registers button. Enter x10000004 for the RegAddress in the Read section. Click the
Read Registers button. Verify x8000 was written to this address. Close this window.
