The BK2190E is a digital storage oscilloscope manufactured by B&K Precision. It is a versatile instrument used in various electronic applications for analysing and measuring electrical signals.

The BK2190E bench oscilloscope combines performance and value all in one portable solution. With advanced triggering capabilities, long waveform memory up to 40,000 points, and extensive features such as pass/fail limit testing, digital filtering, waveform recorder, and 32 automatic measurements, this oscilloscope offers powerful tools in a small affordable package.

The 2190E digital oscilloscope is designed to analyse and measure a wide range of electrical signals, including:
Voltage - amplitude, peak-to-peak value, RMS value, frequency, period, rise time, fall time, duty cycle, and more.
Time - time interval, frequency, period, phase, and delay.
Waveform shape, symmetry, and distortion.
Frequency spectrum - frequency components and harmonics.
Pulse characteristics - pulse width, rise time, fall time, and duty cycle.
These measurements are essential for understanding the behaviour of electronic circuits, components, and systems. The 2190E's advanced features, such as automatic measurements, waveform recording, and pass/fail limit testing, make it a valuable tool for engineers, technicians, and researchers.
