About B&K Precision 2190B Dual Trace Analog
The B&K Precision 2190B is a 100 MHz, two-channel analog oscilloscope 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 oscilloscope 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 oscilloscope 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 oscilloscope is Underwriters Laboratories (UL) certified. Specifications Bandwidth 100MHz Channels Two Display 6" CRT, 8 x 10 division grid Power 100/120/220/240 V AC +/-10%, 50/60Hz, approximately 55W Weight 8.5kg / 18.7lb. Dimensions (H x W x D) 324 x 398 x 132mm / 12.76 x 15.68 x 5.2 inches H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back. Oscilloscopes are electrical testing devices used to verify the functionality of an electrical signal generator. Oscilloscopes 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. Oscilloscopes can display in a digital or analog view. An analog oscilloscope has continuous waveform display, typically in a luminous phosphor. Some oscilloscopes can display more than one channel and type of measurement simultaneously. Some oscilloscopes can capture waveform signals to memory, and recall them. Oscilloscopes may provide real-time intensity grading. Some oscilloscopes have the ability to adjust frequency of display. A constant image will display if a signal is shown at a high frequency. Oscilloscopes 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. Oscilloscopes are commonly used for testing, measuring, and inspecting in science, engineering, telecommunications, automotive, and industry applications. B&K Precision manufactures test and measurement instruments for research and development, production-line testing, and electronic field service applications. The company, founded in 1951, is headquartered in Yorba Linda, CA. It meets International Organization for Standardization (ISO) standard 9001:2008 and is compliant with Restriction of Hazardous Substances (RoHS) and waste electronic and electrical equipment (WEEE) directives.
