The Model LS 1020 Dual-Trace Portable Oscilloscope with 6-inch rectangular, internal graticule CRT features a bandwidth of DC to 20 MHz, maximum deflection factor of 0.5 mV/div (5MHz), and maximum sweep speed of 50 ns/div. Various functions (e.g., TV sync separator, variable holdoff, X-Y display mode) ailow this oscilloscope for educational use as well as production line and service applications of TVs, VTRs, and audio products. * » 2.2 Features • High-sensitivity of 0.5 mV/div Enables measurement of low level signals (e.g., power supply ripple, noise components). • TV-V, TV-H trigger Allows TV video signal observation. Stable display can be obtained by selecting the vertical or horizontal sync signal of the video signal regardless of the TIME/DIV switch setting. • Variable holdoff The variable holdoff time (from the sweep end to sweep start) can display complex waveform stably. • ALT trigger Displays asynchronous waveforms stably. • X-Y display Offers X-Y oscilloscope capability: CH1 for X axis, CH2 for Y axis. • Scale illumination Permits operating the oscilloscope in dark locations, or photographing the screen. • CH1 OUTPUT connector Outputs buffered signal applied to the CH1 input connector. Therefore, the oscilloscope can be used as a wideband, high-sensitivity amplifier.
