Major Instruments & Kits

• Digital Storage Oscilloscope
  A digital storage oscilloscope (often abbreviated DSO) is an oscilloscope which stores and analyses the signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides.

• Mixed Domain Oscilloscope
  Mixed domain oscilloscopes have the ability to display signals in both the time and frequency domains. In the time domain, they can display synchronized analog waveforms, digital waveforms, and decoded serial protocols. For frequency domain analysis, they include an integrated spectrum analyzer signal path.

• Mobile Phone Trainer
  Scientech 2132A Understanding Dual SIM Mobile Phone TechBook is a unique, self contained, easy to operate, training platform that demonstrates the complete arrangement of a 4G Dual SIM GSM handset to understand the working of the mobile phone.

• GSM module
  GSM is the training system which provides users to study GSM/GPRS communication protocol and to experience the overall knowledge about mobile communication through GSM module control. To control the GSM module, there is advanced set of AT Commands according to GSM. GSM is based upon GSM cellular phone and allows for connection to PC for operation and programming. This trainer is designed to instruct the students System operation, Theory, Programming, Servicing, Problem diagnosis of GSM cellular mobile systems. GSM is mainly used for students to learn fundamentals in mobile communication systems such as mobile station network entry, calling process, network signals, AT Commands, Audio communication, Short message services etc.

• DSB/SSB AM Transmitter/Receiver
  DSB/SSB AM Transmitter/Receiver is a comprehensive learning solution specifically designed to study basic operation as well as to provide conceptual and step by step understanding of DSB/SSB Amplitude modulation and transmission system through measurement of voltages and observation of waveforms at various test points. Block wise modular organization of circuit function with supporting technical information makes it easy to understand the process of AM generation and transmission. The exercises conceived to provide a practical approach to the subjects enable a deep analysis of the subjects and will guide the students to understand each function.

• Pulse Code Modulation trainer
  Pulse Code Modulation Technique which is most widely used in digital modulation system. Since analog modulation system is most prone to noise present in the channel and receiver, the digital modulation system is used because it is less sensitive to noise. The basis of digital modulation systems lies on pulse code modulation i.e. a particular characteristic of the pulse is varied in accordance with the information signal. In PCM system the amplitude of the sampled waveform at definite time intervals is represented as a binary code.
