Choose this transmitter when you want 1 kHz and 2 kHz test tones, switched faults and three transmitter–receiver connecting modes on one panel. The demodulation kit is a separate two-channel TDM PCM receiver that can be quoted on the same enquiry.
What Is the TDM PCM Transmitter Used For?
Pulse code modulation samples an analog signal, quantises each sample and codes it as a binary word; parallel-to-serial conversion then sends the bits one after another. Time division multiplexing gives each channel its own time slot in a repeating frame, so two signals share one line, and a pseudo-random sync code marks the start of each frame so the receiver can find it. Parity and Hamming check bits let errors be detected, and the switched faults show what happens when a link or code goes wrong. Working through the three connecting modes — from separate sync, clock and data lines down to data alone — shows how much timing information a receiver has to recover, a key idea in digital communication practicals for diploma and engineering courses.
What to Specify When Ordering
- Quantity — the number of transmitters for your communication lab.
- Receiver — the TDM Pulse Code Demodulation Kit and other PCM trainers are separate items for the same quotation.
- Bench instruments — oscilloscopes are separate catalogue items and can be quoted on the same enquiry.
Frequently Asked Questions
What test signals are on the board?
A sine wave generator at 1 kHz and 2 kHz with amplitude adjustable to about 10 Vpp, and two variable DC levels of +5 V.
Which error check codes can be selected?
Off, odd parity, even parity and Hamming code.
How fast does it run?
In fast mode at about 240 kHz per channel, and in slow mode at about 1 Hz per channel.
What is supplied with the transmitter?
A power cord, patch cords and an instruction manual.
What mains supply does it need, and how big is it?
It runs on 220 V AC +10% at 50 Hz, measures 430 x 230 x 90 mm and weighs about 2.5 kg.
What should an export enquiry include?
The quantity, the destination country and port or city, delivery terms such as FOB or CIF, packing or labelling needs, and the tender reference if the order is for a tender.
Who manufactures this PCM transmitter?
JLab — Jain Laboratory Instruments Pvt Ltd — makes it at its works in Ambala, Haryana, and quotes for it as the manufacturer.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electronics and communication lab equipment manufacturer in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The transmitter is produced at JLab’s own works rather than resold from a trader, so colleges, polytechnics, dealers and importers buy from the maker and place repeat orders with the same team. JLab exports worldwide and ships to buyers in every region — for example Turkey in the Middle East, New Zealand in Oceania, Ethiopia in East Africa, Spain in Southern Europe and Cameroon in Central Africa. See the JLab lab tenders page for tender information.
