Page 16: Convolutional Encoder Option - Ce
TIMTER™ Multi-mode Dual Telemetry Transmitter 1.3.14 Convolutional Encoder Option – CE The CE option enables convolutional encoding and NRZ-M conversion. This encoding adds redundant information to the transmitted data stream to help detect and correct bit errors that may occur, particularly due to predominantly Gaussian noise.
Page 17: Clock-Free Baseband Interface Option - Cf
1.3.20 High Bit Rate Option – HR The standard TIMTER supports bit rates from 0.1 to 28 Mbps in SOQPSK-TG and MULTI-h CPM modes, 0.05 to 14 Mbps in PCM/FM (Tier 0) mode and in all legacy modes. The HR option increases the bit rate to a maximum of 46 Mbps (23 Mbps for PCM/FM).

Legacy Dual Transmitter, refer to the Legacy Dual Transmitter user manual. Figure 49: Quasonix Dual Transmitter Configuring STC and LDPC in a lab or bench set up requires emulating a field set up, some aspects of which may not be intuitively obvious.
Page 109: Compact Receiver
TIMTER™ Multi-mode Dual Telemetry Transmitter 11.1.1 Compact Receiver The Compact receiver normally requires only a single direct connection of the RF input from a transmitter, as shown in Figure 51. Figure 51: Example Bench RF Configuration for Single Transmitter and Compact Receiver For STC, the Compact receiver still requires only a single RF input but it must be the combined RF outputs from Channel 1 and Channel 2 of the dual transmitter, as shown in Figure 52.
