Figure 3-42 FPGA Configure 3/5
FPGA Configure 3/5 consists of registers whose values are written immediately to the
FPGA when changed through the GUI.
FPGA re-initialization shall occur automatically after any of these registers are changed.
The parameters of the FPGA Configure 3/5 screen are as follows.
• Transmitter Delay: (Time in microseconds – see below for calculations)
• NTWK Geog Delay: (Time in microseconds – see below for calculations)
The value for Transmitter Delay shall be displayed in integer microseconds with a valid
range and the value for the FPGA register value calculated (rounded up to the next integer
value) as shown in the following table:
The value for Network Geographic Delay shall be displayed in integer microseconds with
a valid range and the value for the FPGA register value calculated (rounded up or down to
the next integer value) as shown in the following table:
