To configure the

Tx Data Rate

(in kbps), on the top line select the digit of Data Rate to be edited

using the

arrow keys. Press

ENTER

when done.

The maximum limits for the Tx Data Rate are

16 kbps

9.98 Mbps

. The resolution is

1 bps

The actual minimum and maximum data rates are dependent on Framing mode, Interface type,
Modulation type and FEC Code Rate. If the user changes any of the higher-priority parameters –
causing the data rate to become invalid – the

Tx Data Rate

is adjusted automatically. The upper

range of data rate will also be dictated by the FAST option(s) installed.

To configure the

Tx Symbol Rate

(in ksps), on the bottom line select the digit of Symbol Rate to

be edited using the
