Product Code : SCL-CE-12496
Indian Lab Suppliers supplies the CDMA - DSSS/FHSS Trainer (Product ID: 12496), part of the Communication Equipment range under Laboratory equipment, a two-channel trainer covering the design issues behind CDMA using Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
Quick Answer
The trainer provides a basic understanding of the concepts behind CDMA and the various issues that need to be considered in the design of a DSSS/FHSS system. These include the generation of various pseudorandom (PN) codes with programmable tappings, variable chip rate, and digital modulation with a programmable FIR low-pass filter. Overall data-rate dependency parameters and spreading/despreading with DSSS can also be studied on the model.
Experiments
Study of data and PN sequence generation · study of Direct Sequence Spread Spectrum (DSSS)-based modulation · study of demodulation of DSSS modulation · study of generation of PN sequence · study of generation of FHSS modulation signal · demodulation of FHSS modulation.

Why Buy from Indian Lab Suppliers
Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this CDMA - DSSS/FHSS Trainer alongside its broader Communication Equipment catalog, with documentation such as a Certificate of Origin available on request for institutional and export orders.
Frequently Asked Questions
What is the difference between the DSSS and FHSS sections of this trainer?
DSSS spreads the signal using an 11-chip spreading sequence for a throughput of about 7 Mbps (of an 11 Mbps system), while FHSS hops across four carrier frequencies (128, 64, 32 and 16 kHz) for a throughput of about 2 Mbps (of a 3 Mbps system).
Do I need any additional equipment to use this trainer?
Yes, a digital storage oscilloscope is required separately to observe the signals.
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.
