bap8guy | BK1540 40Mhz Dual Trace, Dual Time Base, Delayed Sweep Oscilloscope @bap8guy | Uploaded March 2023 | Updated October 2024, 1 day ago.
This is a dual trace, 40Mhz scope, with two time bases, making it capable of delayed sweep (B) magnification of the observed trace (A). It also can display traces individually, or together using either alternating or chopped mode. It can add or subtract the two channel’s waveforms. It covers 1millvolt per division up to 5 volts per division on an 8x10 division screen, where each division is 10mmx10mm, yielding an 80mmx100mm graticule screen area (3”x4”). It can perform in XY mode, allowing for Lissajous pattern measurement (good for frequency alignment).
On the rear there is an input for Z axis information and outputs for the Gate, Sweep, and Channel 1 signal information.
In this video I demonstrate the testing of the vertical calibration, horizontal calibration, test/demonstrate the majority of controls, demonstrate the use of Delayed Sweep and the "B" time base, demonstrate the use of Lissajous patterns for calibrating frequency of a unit to a standard and more.
40Mhz makes it useful for DC, audio, ultrasonics, AM Radio and well into shortwave radio. It is a perfect beginner, intermediate electronics enthusiast tool, loaded with feature but lower in price.
