Product Code : SCL-CE-12491
Indian Lab Suppliers supplies the TDM Pulse Code Modulation and Transmitter Trainer (Product ID: 12491), part of the Communication Equipment range under Laboratory equipment, a trainer providing all the inputs and connections students need to study Pulse Code Modulation (PCM) transmission techniques combined with Time Division Multiplexing.
Note on naming and scope: our catalog also includes the TDM Pulse Code Modulation Trainer (Product ID 12573); please confirm the exact model with our team. That trainer is a simpler, standalone two-channel TDM-PCM demonstration board with fast/slow mode switching and PLL bit synchronization, without the error-check coding, fault-insertion switches or RS232 PC-to-PC communication that this paired transmitter/receiver system provides.
Quick Answer
This trainer provides all necessary inputs and connections for students to study Pulse Code Modulation transmission techniques over two time-division-multiplexed analog channels, with a pseudo-random sync code generator, selectable error-check coding (odd/even parity or Hamming code) with switched fault insertion, and PC-to-PC communication over RS232 in three connection modes. A full communication link can be established using a matching PCM receiver.
Key Features
Crystal-controlled clock · on-board synchronized sine wave generator · 2 TDM analog channels · PCM transmitter · fast and slow modes for real-time operation and data-flow examination · error-check code options (odd/even parity, Hamming code) · 4 switched faults for different error-check scenarios · PC-to-PC communication via RS232 interface.
Experiments
Pulse Code Modulation · A/D conversion and parallel-to-serial data conversion · Time Division Multiplexing of PCM data · synchronization by pseudo-random code · error-check codes with switched faults · connecting modes between transmitter and receiver (1: sync, clock and data lines connected; 2: clock and data connected; 3: data only) · study of the effect of induced faults · PC-to-PC communication in 3 modes.

Frequently Asked Questions
What error-check coding options are available?
Off, odd parity, even parity, or Hamming code, with 4 switched faults available to test different error-check scenarios.
How does PC-to-PC communication work with this trainer?
Two channels communicate via RS232 (9-pin D-type connectors), with a selectable baud rate from 300 to 2400, across three connection modes (sync+clock+data, clock+data, or data only).
Do I need another unit to form a complete communication link?
Yes — pair this transmitter with our TDM Pulse Code Modulation Receiver Trainer (Product ID 12492), which shares the same fast (320 kHz/channel) and slow (1.9 Hz/channel) operating speeds and error-check code options (off/odd/even parity and Hamming code), confirming it is designed as the matching receiver for this trainer.
Do you supply this equipment for institutional or export orders outside India?
Yes. Indian Lab Suppliers quotes equipment for institutional and tender buyers across export markets — see the Tenders page for documentation requirements.
