2.11.1.5 Verify Configuration of FPGA Screens
When configuring an exciter for the first time, it is useful to check the setting s in the
FPGA screens. The exciter manual gives detailed information on settings but the values
on FPGA screen 4/5 are especially importatant.Values shown in Figure 2-11 are typical
for 6 MHz operation but may need to be updatedto meet on-site operational
requirements.
Figure 2-11 FPGA Configure 4/5
FPGA Configure 4/5 consists of registers whose values are written immediately to the
FPGA when changed through the GUI.
FPGA re-initialization shall occur automatically after any FPGA Configure 4/5 register is
changed.
The parameters of the FPGA Configure 4/5 screen are as follows.
• Bandwidth: 5MHz / 6MHz / 7MHz / 8MHz.
• National Length: Unsigned Decimal, range dependent on bandwidth:
0-245 5MHz, 0-295 6MHz, 0-345 7MHz, 0-395 8MHz. XXX Define
• Pos. Pilot Length: 2 / 6 / 10 / 14 – not bandwidth dependent. XXX Define
• WID: Unsigned Decimal, range 0-15. XXX Define
