TDM Pulse Amplitude Modulation and Demodulation Trainer Manufacturer,Supplier and Exporter in India
Product Code : SCL-CE-12490
Indian Lab Suppliers supplies the TDM Pulse Amplitude Modulation and Demodulation Trainer (Product ID: 12490), part of the Communication Equipment range under Laboratory equipment, a trainer demonstrating Pulse Amplitude Modulation (PAM) combined with Time Division Multiplexing (TDM) across three selectable transmitter/receiver communication modes.
Note on naming and scope: our catalog also includes the TDM Pulse Amplitude Modulation/Demodulation Trainer (Product ID 12572); please confirm the exact model with our team. Both trainers cover TDM-PAM multiplexing/demultiplexing across four analog input channels, but the documented specifications differ — this trainer is documented with an 8 MHz crystal and a three-mode (3-signal/2-signal/1-signal) transmitter-receiver communication scheme, while Product ID 12572 uses a 6.144 MHz crystal-controlled pulse generator with PLL-based clock regeneration and a 4th-order Butterworth low-pass filter at the receiver.
Quick Answer
This TDM-PAM Transmitter and Receiver trainer is a communication system in which the message signal is modulated using Pulse Amplitude Modulation while multiple access is provided using Time Division Multiplexing — the message information is encoded in the amplitude of a series of signal pulses and transmitted in different time slots. The trainer demonstrates three modes of operation between transmitter and receiver: Mode 1 sends 3 signals (clock, sync and modulated signal); Mode 2 sends 2 signals (sync and modulated signal), with the clock recovered at the receiver; and Mode 3 sends just 1 signal (the modulated signal), with both clock and sync recovered at the receiver.
Key Features
Crystal-controlled clock · on-board synchronized analog signal generator (DC and sine wave) · demonstrates sampling and reconstruction as per the Nyquist criterion · four switch-selectable sampling frequencies · switch-selectable sampling pulse duty cycle · on-board pulse generator · four analog input channels to demonstrate TDM-PAM · clock generation at the receiver via PLL · fourth-order Butterworth low-pass filter.
Experiments
Pulse Amplitude Modulation technique · Time Division Multiplexing and demultiplexing · PLL as a frequency multiplier to generate clock from the sync signal · the three modes of operation between transmitter and receiver (3-signal / 2-signal / 1-signal communication) · effect of varying the duty cycle of the sampling pulse on signal reconstruction · effect of different sampling frequencies on the TDM-PAM and demodulation technique.

Frequently Asked Questions
What are the three modes of operation between transmitter and receiver?
Mode 1 transmits 3 signals (clock, sync and modulated signal); Mode 2 transmits 2 signals (sync and modulated signal) with the clock recovered at the receiver; Mode 3 transmits just the modulated signal, with both clock and sync recovered at the receiver via PLL.
How many channels and sampling rates does the trainer support?
4 analog input channels, with 4 switch-selectable sampling rates (32, 40, 50 and 80 kHz per channel) and a switch-selectable sampling pulse duty cycle from 0–90% in decade steps.
Is this related to your Sampling & Reconstruction Trainer?
Yes, it is a complementary trainer in the same digital communication teaching range — see our Sampling & Reconstruction Trainer (Product ID 12489) for the underlying sampling/reconstruction concepts this trainer builds on with TDM-PAM.
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.
