The TOS series analog oscilloscopes are cathode ray oscilloscopes that use cathode ray tube to display signal waveforms. The dual channel oscilloscope is available with 6-digit frequency counter and component tester function. The TOS series analogue oscilloscopes are dual trace oscilloscope suitable for teaching and students. There are different models from the TOS dual channel oscilloscope: Analog oscilloscope 20MHz, Oscilloscope 30MHz, 40MHz analog oscilloscope, Oscilloscope 100MHz. The TOS series scientific oscilloscope can be used as DIY electronic oscilloscope, electronic laboratory oscilloscope, student oscilloscope and CRO oscilloscope.
