Overview 1 The TDR6 is a high performance, modular receiver/decoder providing a high degree of flexibility to meet a variety of Standard Definition (SDTV) and High Definition (HDTV) applications. It’s modular design makes it easy to adapt to changing requirements in digital TV contribution and distribution networks.
The TDR6 supports both single-channel-per-carrier (SCPC) and multi-channel-per-carrier (MCPC) operations and can be deployed in either a point-to-point or point-to-multipoint system. If the TDR6 has been configured to receive satellite transmissions, it will accept input from 950 to 2150 MHz at power levels between -65 dBm and -25 dBm. It can also interface directly with satellite low noise block (LNB) downconverter input at up to 30 Msps, -25 dBm to -65 dBm.
Front Panel The TDR6 front panel interface allows you to scroll through a standard set of menus to easily set your operating parameters. All configuration and monitoring functions can be efficiently performed using the front panel. The TDR6 menu structure will vary according to the option modules installed in your unit, however the standard menus exist in any TDR6 configuration. At-a-glance system status can be quickly determined by checking the front panel power, fault and status LEDs.

Installation Procedure Removal Procedure 80 01-0870-401B 01/03 To install an option module: 1. Before installing option modules, ensure that all configuration parameters specific to your site are recorded. 2. Remove power from the unit. 3. Remove the filler plate from the appropriate slot by unscrewing all end screws. 4. Align the module edges so the module slides down the center of the module guides. 5.
Demodulator Application Notes G This appendix contains additional technical information for the TDEM-6110 Demodulator option module, including information on: ■ Configuration ■ Rates and channel spacing ■ Estimating Eb/N0 ■ Troubleshooting Configuration This section provides technical information to supplement the basic configuration procedures provided in the chapter on configuring the TDR6.
Data Inversion / Spectral Inversion In QPSK modulations, every symbol consists of two bits of data. These two bits are commonly referred two as the I and Q samples. Data inversion occurs when both I and Q are inverted. Spectral inversion occurs when either I or Q are inverted. Spectral inversion is caused by selecting the lower sideband instead of the upper sideband in the mixing and RF filtering process. All Tiernan demodulators automatically check for and compensate for data/spectral inversion.
Information Rates The minimum and maximum information rates are provided in the following table. Minimum and Maximum Information Rates Code Rate 1/2 2/3 3/4 5/6 7/8 Minimum Information Rate (Mbps) 0.92 1.23 1.38 1.54 1.61 Maximum Information Rate (Mbps) 27.6 36.8 41.5 46.1 48.4 Output Spectrum Width To prevent intersymbol interference, the outgoing symbols are filtered by a DVB-compliant transmit filter. The filter type is a square-root raised cosine filter with roll-off factor alpha = 0.
Eb/N0 Estimation Algorithm Within the FEC decoder IC, the Viterbi decoder output is re-encoded and compared to a delayed version of the original encoder input. Incoming bit errors that are corrected will result in a difference between original input and the encoded output. These differences are accumulated for a fixed amount of time. This accumulation register can be read by the TDR6 microprocessor and gives an approximation of the signal to noise level of the input signal.
■ ■ ■ NOTE Measure C/N to estimate Eb/N0 where ❒ C is carrier power ❒ N is noise floor Calculate the estimated Eb/N0 Refer to the equation for estimating Eb/N0 using a spectrum analyzer in a previous section of this appendix. Transmit pure carrier to precisely locate the center frequency If the demodulator is supplying the DC to the LNB, then the spectrum analyzer must monitor the L-band input using a T-junction. Insure that the spectrum analyzer input is protected using a DC-block.
■ ■ Viterbi Bit Error – This register displays the number of channel bit errors during the last measurement period. This register is used to estimate Eb/N0. If this register is zero, the Eb/N0 is 16.00 (no noise). Any channel noise will cause this register to be greater than zero. OFFSET – Use this command to confirm the location of the carrier. The definition of this query is: (OFFSET = Actual RF – Programmed RF) The units are in Hz. Syntax – DMD.
