Oscilloscope with Frequency Counter The Economic Oscilloscope establishes a brand new benchmark for the Oscilloscopes within the Same category. New and innovative functions, including LCD Readout Display, Frequency Counter, and Auto Time-Base setting, are provided as standard features, with a 30 MHz bandwidth and valuable features, is priced at the basic Oscilloscope level. 1 mV/div High Vertical Sensitivity is able to capture small signal variations in the input source. Additional functions such as XY mode display, MAG function (Time based Magnified), and Z-axis Input extend the application range of 72-6802 to both education and industry fields. The added values without being converted into extra cost make the 72-6802 the most beneficial choice among the entry-level analog oscilloscopes available in todays market.
