Tx Modulation Type, where:
0 = Rate 3/4
1 = Rate 7/8
2 = Rate 3/5
3 = Rate 4/5
4 = Rate 5/6
5 = Rate 8/9
6 = Rate 9/10
7 = Rate 2/3
8 = Rate 1/2
Depending on FEC type, not all of these selections will be valid.
Example: TCR=0 (which is Rate 3/4)
*NOTE: Please refer to Chapter 8 for a list of available code
rates for each mode.
Tx Symbol Rate, where:
s=Symbol Rate in Msps
Example: TSR=20.000000 (20 Msps.)
Tx Frequency (in MHz)
52 to 88 MHz, and 104 to 176 MHz (70/140 Modulator)
950 to 1950 MHz (L-Band Modulator)
Resolution=100Hz.
Example: TFQ=0950.0000
