Frequency Modulation Recording: When a more accurate response to dc voltages is required, an Frequency Modulation Recording system is generally used. In this FM system, the input signal is used…
Spectrum Analyzer Block Diagram: Spectrum Analyzer Block Diagram - The most common way of observing signals is to display them on an oscilloscope, with time as the X-axis (i.e. amplitude…
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…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive…
Digital Readout Oscilloscope: The Digital Readout Oscilloscope instrument has a CRT display and a counter display. The diagram shown is of an instrument where the counter measures the time (Fig.…
What is Sampling Oscilloscope?: An ordinary Sampling Oscilloscope has a B.W. of 10 MHz. The HF performance can be improved by means of sampling the input waveform and reconstructing its…
What is Electronic Switch in Oscilloscope?: The electronic switch is a device that enables two signals to be displayed simulÂtaneously on the screen by a single gun CRT. The basic…
Horizontal Deflection System in CRO: The Horizontal Deflection System in CRO consist of a Time Base Generator and an output amplifier. Sweep or Time Base Generator: A continuous sweep CRO…
