TDR60 Front Panel Menu Summary

Description
Parameters or Response Format
Input: The Input menu contains the Config and Status submenus
Input>Config: allows you to set the input type, LO frequency, RF frequency, code rate, symbol rate, data rate, and LNB power.
Input Type
Sets the input type.
Note
: This setting effects the commands available on the
Input>Config and Input>Status menus.
■
Demod – selects input from the RF port
■
ASI – selects input from the ASI port
Default: Demod
RF Freq
Sets the satellite downlink RF frequency of the channel you wish to
receive.
Note
: Only available when Input>Config>Input Type = Demod.
950 - 2150 MHz
Default: 11210MHz
LO Freq
Sets the Local Oscillator frequency.
The RF frequency input range of the TDR60 is between 950 to
2150 MHz. To downconvert the satellite downlink RF frequency to
a frequency that is within the input range of the TDR60, you must
enter an LO frequency that is the difference between the satellite
downlink RF frequency and the TDR60 RF input frequency range.
Typically, the LO frequency required is provided by the satellite
carrier; however, if the LO frequency is not provided by the carrier,
use the following chart to determine the LO frequency.

11300 MHz
Note
: Only available when Input>Config>Input Type = Demod.
2000 MHz - 15000 MHz
Default: 10000MHz
Code Rate
Sets the FEC code rate of the transport stream.
Note
: Only available when Input>Config>Input Type = Demod.
1/2, 2/3, 3/4, 5/6, 7/8
Default: 5/6
SymRate
Sets the symbol rate.
To convert the data rate to the symbol rate, use the following
equation:
The Data Rate (DatRate) and Symbol Rate (SymRate) must be
entered in Mbps and MSps., respectively. These values must
include a decimal point. For example, to enter a data rate of
8448000 bps, you would use the numeric keypad to enter the
following rate in Mbps 8.448 — the trailing zeros do not need to be
entered. To enter a symbol rate of 5000000 sps, you would type in
a 5 using the numeric keypad. In this case, the decimal point and
trailing zeros are not needed.
Note
: Only available when Input>Config>Input Type = Demod.

Default: 5.500187 MSps
