Short Description

Model : Amplitude Mod. /Demod. without Product Detector & Spectrum Analyser. Modulator Carrier Freq : 100KHz Types of Detector : 1.Diode Type with variable RC Oscillator : Built-in : 2.Product / Square Law detector, local freq 100KHz. Types of Amp. Modulation : 1.DSB with Carrier 2.DSBSC (Suppressed carrier) Local oscillator : Can be locked in phase or can run out of lock w.r.t.100KHz Carrier Osc. Spectrum Analyser: Built-in for measurement & detection of side bands in the modulated signal. The instrument works on 230/115 V + 10%, AC Single Phase • Study of slope distortion caused by excessive time constant in detector circuit. • Measurements of side bands present in the modulated signal by spectrum analyser. • Changing the time constant of the detector circuit and seeing its effect on Modulation Economy
