The B&K Precision 1541D is a 40 MHz, two-channel analog oscillo with ALT triggering, hold-off function, pull chop switch, and TV synchronization capability with high- and low-frequency rejection for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education, among others. This oscillo has a vertical sensitivity to 5mV per division for the full bandwidth and to 1mV per division when the gain control is engaged for capturing low-level signals. An ALT triggering function displays the signal from both channels simultaneously and a hold-off function stabilizes complex signals. The pull chop switch toggles to display two sweeps either simultaneously or alternately. The TV synchronization circuit allows triggering of TV-V and TV-H signals and serves as a high- and low-frequency rejection circuit that removes interference from a signal to prevent false triggering. Sweep speed can be magnified by 10 to increase the number of sweeps shown on the display. Additional specifications ( https://images-na.ssl-images-.com/images/G/01/BISS/OscillosMix/B000LDO19M.spec_sheet.pdf ) include a rise time of 8.8 ns and various triggering features. The oscillo has a 6" CRT (cathode ray tube) display with an internal 8 x 10 division grid (each division is 1 cm) for viewing waveforms. It is Underwriters Laboratories (UL) certified. It comes with two voltage probes; a power cord for 100 to 230V/200 to 260VAC, 50/60 Hz; a spare fuse; and instructions.

Oscillos are electrical testing devices used to verify the functionality of equipment that generates an electrical signal. Oscillos measure the voltage of an electrical signal over time, and display the measurement as a waveform in a visual graph. The waveform shows the sweeps (or refresh) of voltage on a vertical (Y) axis, and the time on a horizontal (X) axis. Details of a waveform demonstrate the signal over time. Most oscillos have two or four channels for inputting a signal. Some digital oscillos offer more than four channels, allowing channels to be dedicated to specific signals and applications. Bandwidth is the maximum frequency of a signal that an oscillo can capture. A constant image will display if a signal is shown at a high frequency. Oscillos may be analog, digital, or mixed signal. An analog oscillo directly displays an input signal as a continuous waveform, typically in a luminous phosphor on a cathode ray tube (CRT). A digital oscillo converts the input signal into a digital format and reassembles the waveform for display, typically on an LCD. A mixed signal oscillo (MSO) displays both analog and digital formats. Some oscillos can display more than one channel and type of measurement simultaneously. Some oscillos can capture waveform signals to memory, and recall them. They may provide real-time intensity grading, and may have the ability to adjust frequency of display. Oscillos can be powered with batteries or electricity, or may have a built-in generator. They are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and electronics applications.
