11.3.2 Adjustment of ASIC values

With the ASIC Control screen open, use the TAB key on the P C keyboard to tab along until the

required parameter is highlighted.

Note; Only parameters within the Rx or Tx mode can be accessed.

Once the required parameter is highlighted, make adjus tments using the PgUp and PgDn keys on the

PC keyboard.

For the transmitter, the following parameters can be adjusted ( see Figure 11-4):
