SIMPLIFIED SPECTRUM ANALYSER

BHI-ENE-2202
Qty Comments

OBJECTIVES

To determine the operating principles and circuits of a basic spectrum analyser.

In this simplified analyser, a sweep generator is used to provide an external input to the oscilloscope and at the same time, to change the voltage on the control circuit of a voltage controlled oscillator. Thus the oscillator frequency varies as a sweep moves across the CRT. The unknown frequency, in this case from the signal generator is next mixed with the signal from the VCO. As with any mixer, sum and difference frequencies are produced, but only the difference will be processed.

DIMENSION :41.5cms x 31.5cms x 13.5cms.

WEIGHT : (Approx.) 1 KG.
