Step 2: By comparing your system requirements to the
■Input
■Modulation
■RF Freq
■LO Freq
■Code Rate
■LNB Power
Step 3: To change these parameters the following front panel or remote commands can be used.
Parameter | Front Panel Menu | Remote | |
Command | |||
|
| ||
|
|
| |
Input | Details>Input>Config>Select>Input = RF_A | DC INPUT RF_A | |
|
|
| |
Modulation | Details>Input>Config>Demod>RF_A> | DMD.A MOD | |
| Modulation = QPSK | QPSK | |
|
|
| |
RF Freq | Details>Input>Config>Demod>RF_A> | DMD.A RF 11774 | |
| RF Freq = 11774 |
| |
|
|
| |
LO Freq | Details>Input>Config>Demod>RF_A> | DMD.A LO 10750 | |
| Lo Freq = 10750 |
| |
|
|
| |
Code Rate | Details>Input>Config>Demod>RF_A> | DMD.A CR 5/6 | |
| Code Rate = 3/4 |
| |
|
|
| |
LNB Power | Details>Input>Config>Demod>RF_A> | DMD.A LNB 13V | |
| LNB Power = 13V |

Step 4: This example assumes that the TDR6 has been previously initialized to the DVB default settings.
Step 5: Assuming the TDR6 is set to the DVB defaults settings, the new parameters must be entered.
1.Set the TRD6 input to RF using either the front panel
Details>Input>Config>Select>Input>RF A option or the remote command DC INPUT RF_A.
2.Se the Modulation type using either the front panel
Details>Input>Config>Demod>RF_A>Modulation QPSK or the remote command DMD.A MOD QPSK.
3.Set the RF frequency using either the front panel
Details>Input>Config>Demod>RF_A>RF Freq 11774 or the remote command DMD.A RF 11774.
4.Set the LO frequency using either the front panel
Details>Input>Config>Demod>RF_A>LO Freq 10750 or the remote command DMD.A LO 10750.
5.Set the code rate using either the front panel
Details>Input>Config>Demod>RF_A>Code Rate 3/4 or the remote command DMD.A CR 5/6.
6.Set the LNB voltage using either the front panel
Details>Input>Config>Demod>RF_A>LNB Power 13V or the remote command DMD.A LNB 13V.
