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.
Waveform recorder
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.
Delayed sweep/zoom
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.
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.
Large internal storage
Pass/Fail testing
Minimize debug time by saving and recalling setups and waveforms
from internal memory. Save and recall up to 20 different oscilloscope
setups and 20 different waveforms.
Generate user-defined pass/fail limits to quickly identify go/no go
test results.

PR150B
The included EasyScope software provides 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.
PR250B & PR500B
Avoid limiting the bandwidth of your measurement system. All 2550
series models come standard with high bandwidth, slimline passive
probes (one per channel) to help you get the most out of your scope.
