    1 General Information 1.1 Product Overview The B&K Precision 2190E digital storage oscilloscope (DSO) is a portable benchtop instrument used for making measurements of signals and waveforms. The oscilloscope’s bandwidth is capable of capturing up to 100 MHz signals with a real time sampling rate of up to 1 GSa/s. With up to 40k points of deep memory, more details of a signal can be captured and displayed on a large color LCD display for analysis.
