Category: Measurement instruments
Group: Oscilloscope
Description: 20 MHz OSCILLOSCOPE
Information:
                                    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.
