    • EWB Instruments IV-analysis Distortion analyzer Network analyzer Measurement probe Spectrum Analyzer
    • Multimeter Schematic symbol Display Current (Ampere) Voltage (Volt) Resistance (Ohm) Power (Decibel) Alternating current (AC) + probe - probe Direct current (DC) + probe - probe
    • Multimeter (DC measurement) DC setting Voltage measurement Current measurement
    • Multimeter (AC measurement) AC setting Voltage measurement Current measurement
    • Function Generator Schematic symbol Sinusoidal wave Sawtooth wave Square wave + probe - probe + probe - probe
    • Function Generator Voltage measurement Current measurement Function generator
    • Wattmeter Voltmeter Schematic symbol + - Ammeter + - Display (Wattage) Power factor
    • Wattmeter Voltage measurement Current measurement
    • Oscilloscope Channel A Schematic symbol Channel B Ground Trigger Toggle between black and white screen Vertical cursor 1 Vertical cursor 2 Vertical cursor 1 (Readouts) Vertical cursor 2 (Readouts) Difference between cursor (Readout) Saving in ASCII text file
    • Oscilloscope Measure input signal Measure output signal
    • 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.
    • Bode plotter Measure input signal Measure output signal Magnitude versus frequency Phase versus frequency
    • 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
    • Frequency Counter 555 timer 1 kHz configuration Actual output frequency Duration of 1 cycle
    • Frequency Counter 555 timer 1 kHz configuration Duration of positive pulse Duration of negative pulse Rise time of a single counter
    • 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.
