Audio board frequency block assignment
Prerequisite(s): FPGA IC programmed
Note:
This part has to be performed only on the first DUT to setup Test Audio Board for the Block.
Momentarily connect audio board TP5 to TP22 (enter Set-up mode)
Note
Entering Set-up mode is not necessary if the Alternate Method is exercised.
Using the test key pad navigate to the "Block" screen.
Press UP or DWN button on the test panel key pad to change unit to desired Block
block= (set freq block 470,19-33, 944 standard 400-999 extended)
Turn DUT Off then back On and check to see if the Block set.
