Potentiometric Recorder Working Principle (Multipoint): Potentiometric Recorder Working Principle - The thermocouple or millivolt signal is amplified by a non-inverting MOSFET, chopper stabilized, feedback amplifier. This configuration has a very…
Null Type Recorder: These Null Type Recorder Working Principle of self-balancing or null conditions. When an input is given to the measuring circuit of the recorder from a sensor or transducer,…
Oscilloscope Operating Precautions: In addition to the general safety precautions, the following specific precautions should be observed when operating any type of oscilloscope. Most of the Oscilloscope Operating Precautions also…
Fibre Optic CRT Recording Oscilloscope: Fibre Optic CRT Recording Oscilloscope - The familiar CRT oscilloscope has an extremely HF response, but permanent records, normally photography of the screen, cannot be…
Probes for CRO: Direct Probes (1 : 1): The simplest types of Probes for CRO (one can hardly call it a probe) is the test lead. Test leads are simply…
Dual Trace Oscilloscope: Figure 7.19 (a) shows a block diagram of Dual Trace Oscilloscope. This CRO has a single electron gun whose electron beam is split into two by an…
Vertical Amplifier: The sensitivity (gain) and frequency bandwidth (B.W.) response characteristics of the oscilloscope are mainly determined by the vertical amplifier. Since the gain B.W. product is constant, to obtain…
Transistor Voltmeter (TVM): Transistor Voltmeter - Direct coupled amplifiers are economical and hence used widely in general purpose low priced VTVM' s. Figure 4.9 gives a simplified schematic diagram of…
