• 100MHz, two-channel analog oscillo for electronics applications such as product design, assembly lines, repair and servicing, and electrical engineering education.
• Vertical sensitivity to 1mV per division for capturing low-level signals.
• ALT triggering function allows simultaneous signal viewing of both channels.
• Hold-off function stabilizes complex signals for display.
• 6" CRT display with an internal 8 x 10 division grid for viewing waveforms.

The B&K Precision 2190B is a 100 MHz, two-channel analog oscillo with ALT triggering, hold-off function, delayed sweep, 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 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 can be delayed to display a waveform and zoom-in simultaneously, and speed can be magnified by 10 to increase the number of sweeps shown on the display. Additional specifications include a rise time of 3.5ns and various triggering features. The oscillo has a variable-illumination 6" CRT (cathode ray tube) display with an internal 8 x 10 division grid (each division is 1cm) for viewing waveforms. This analog oscillo is Underwriters Laboratories (UL) certified.

Oscillos are electrical testing devices used to verify the functionality of an electrical signal generator. Oscillos measure an electrical signal over time, and display the waveform signals in a visual graph. The waveform shows the sweeps (or refresh) of voltage on a vertical (Y) axis, and can display time on a horizontal (X) axis. Details of a waveshape demonstrate the signal over time. Oscillos can display in a digital or analog view. An analog oscillo has continuous waveform display, typically in a luminous phosphor. Some oscillos can display more than one channel and type of measurement simultaneously. Some oscillos can capture waveform signals to memory, and recall them. Oscillos may provide real-time intensity grading. Some oscillos have the ability to adjust frequency of display. A constant image will display if a signal is shown at a high frequency. Oscillos can be powered with batteries or electricity, or may have a built-in generator. They may have Canadian Standards Association (CSA) or European Conformity (CE) certification, or a specific category (CAT) safety rating, such as CAT5e. Oscillos are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and industry applications.
