Ecd302 unit 03 (part b)(instrument)(b)

  1. 1. Electronics Workbench (EWB) Instruments (part b)
  2. 2. EWB Instruments IV-analyzer Distortion analyzer Network analyzer Measurement probe Spectrum Analyzer
  3. 3. IV analyzer Schematic symbol Probe This feature is not available in all versions of Multisim. The IV Analyzer is used to measure the current-voltage characteristic curves of the following devices: Diode, BJT (PNP & NPN), MOSFET (PMOS & NMOS). Symbol map Select the type of device
  4. 4. IV analyzer 1A Rectifying diode Comparison
  5. 5. IV analyzer Comparison
  6. 6. IV analyzer Comparison
  7. 7. Spectrum analyzer Schematic circuit Probe Spectrum analyzer is used to measure amplitude versus frequency. This instrument is capable of measuring signal's power and frequency components, and helps determine the existence of harmonics in the signal. One area that has an interest in spectrum measurement is communications. For example, cellular radio systems must be checked for harmonics of the carrier signal that might interfere with other RF systems. Other interesting applications of spectrum analysis are distortions of the message modulated onto a carrier.
  8. 8. Spectrum analyzer Are these harmonics? The spectrum analyzer displays its measurements in the frequency domain rather than the time domain.
