Technical data subject to change

The 2190D combines performance and value all

in one portable solution. With 100 MHz

bandwidth and 1 GSa/s sample rate, these

oscilloscopes offer 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.

Engineered to allow you to see more of your

signal under test, the 2190D widescreen 7” TFT

display offers a significantly larger viewing area

than typical economy oscilloscopes (5.7”).

Maximize productivity with PC connectivity via

RS232 and USB. The downloadable PC software

lets you easily capture, save, and analyze

measurement results. All oscilloscope parameters

can be controlled via a PC without the need for

programming.

The 2190D oscilloscope is ideal for applications

in education, design and debug, service and

repair.

PC connectivity

PC software is provided (free download at B&K

Precision’s website at www.bkprecision.com) for

seamless integration between the oscilloscope

and PC. Capture and transfer waveforms, screen

images, setups and measurement results to a

Windows PC via the USB device port on the

back of the instrument. A USB host port on the

front and rear allows for quick and easy screen

saving.

The tools you need

Display and measure the input signal’s frequency spectrum. Select

one of the 4 FFT windows: Rectangular, Hanning, Hamming, and

Blackman. Use cursors to measure the spectral component’s

magnitude and frequency.

Monitor and analyze long-term signal behavior by recording data

continuously over an extensive period of time and playing it back for

post acquisition analysis. Data is recorded in a sequence of up to

2500 frames.

Minimize debug time by saving and recalling setups and waveforms

from internal memory. Save and recall up to 20 different oscilloscope

setups and 10 different waveforms.

Filter out unwanted signal components such as various types of noise

with built-in digital filters. Choose from Low-Pass, High-Pass,

Band-Pass, and Band-Stop filters.

Generate user-defined pass/fail limits to quickly identify go/no go

test results.

Use the oscilloscope’s delayed sweep feature to zoom in a particular

area of a signal in real time while viewing the entire captured

waveform simultaneously.
