  12. 12. Oscilloscope Measure input signal Measure output signal
  13. 13. Bode plotter Schematic symbol Input signal channel Output signal channel A Bode magnitude plot is a graph of log magnitude versus frequency, plotted with a log-frequency axis, to show the frequency response of a linear system. A Bode phase plot is a graph of phase versus frequency, also plotted on a log-frequency axis, usually used in conjunction with the magnitude plot, to evaluate how much a frequency will be phase-shifted.
  14. 14. Bode plotter Measure input signal Measure output signal Magnitude versus frequency Phase versus frequency
  15. 15. Frequency counter Schematic symbol Frequency counter is used to measure signal frequency Frequency Probe Display The minimum sensing voltage Trigger level is the point that must be reached by the waveform before a reading is displayed Display only the AC component of a signal Display only the DC component of a signal
  16. 16. Frequency Counter 555 timer 1 kHz configuration Actual output frequency Duration of 1 cycle
  17. 17. Frequency Counter 555 timer 1 kHz configuration Duration of positive pulse Duration of negative pulse Rise time of a single counter
  18. 18. Logic analyzer Schematic symbol Signal Probe External clock Clock qualifier Trigger qualifier The logic analyzer displays up to 16 digital signals in a circuit. It is used for fast data acquisition of logic states and advanced timing analysis to help design large systems and carry out troubleshooting.
