GGq838 electronic technology data - electronic components - circuit diagrams - technical application sites - basic knowledge - Principles - maintenance - acting - parameters - Symbols for electronic components Figure 1 oscilloscope appearance gGq838 electronic technology data - electronic components - circuit diagrams - technical application sites - basic knowledge - Principles - maintenance - acting - parameters - Symbols of electronic components (1) POWER3 (power switch): it is the power switch of oscillograph. Usually there is an indicator light next to the 2. The light indicates that the oscilloscope is energized.
