The lab has state of the art test and measurement equipments for carrying out experimental research in RF/Wireless Electronics. The major ones are:

• High frequency Spectrum Analyzer (up to 6.7 GHz)

• High frequency Signal Generator (up to 4 GHz)

• High frequency Digital Oscilloscope (up to 4 GHz)

• Network Analyzer (up to 3 GHz)

• Digital Storage Oscilloscope (up to 200MHz)  

• Spectrum Analyzer (up to 200MHz)

• Arbitrary Waveform generator (up to 500MHz)

   

   

  

  
  

In addition to these high performance equipments lab has several Signal generators, Oscilloscopes (analog and DSO), Regulated power supplies and other necessary infrastructure for experimental research.

The lab possesses Ansoft® HFSS a powerful 3D EM simulator for analysis of microwave structures along with other computational soft wares and EDA tools.

INTEL IXP NETWORK PROCESSOR EVALUATION PLATFORM :

IXP 2400 Network Processor Card

Apart from the above measurement and test facilities, the lab has excellent computing facility with high performance computers for carrying out computational research and simulations. The lab has Intel® IXP1200 and IXP2400 Network Processors and software development kit (SDK) to carry out advanced level research in the area of Communication Networks.

MPLS TEST BED :

Recently, an MPLS test-bed has been set-up for implementation of DiffServ over MPLS-TE. A real-time routing protocol has been implemented on Linux platform. This set-up can be extended for study of multicasting.

OPNET :

Evaluations are carried out over OPNET for scalability analysis of different protocols. OPNET is also used for study and implementation of Inter-domain routing, QOS routing and Diffserv over MPLS-TE.
