PicoScope 4824 8 Channel Oscilloscope
Digital triggering
Most digital oscilloscopes still use an analog trigger architecture
based on comparators. This can cause time and amplitude errors
that cannot always be calibrated out. The use of comparators often
limits the trigger sensitivity at high bandwidths and can also create
a long trigger re-arm delay.
For over 20 years Pico have been pioneering the use of full digital
triggering using the actual digitized data. This reduces trigger errors
and allows our oscilloscopes to trigger on the smallest signals,
even at the full bandwidth. All triggering is digital, resulting in high
threshold resolution with programmable hysteresis and optimal
waveform stability.
The reduced re-arm delay provided by digital triggering, together
with segmented memory, allows the capture of events that happen
in rapid sequence. At the fastest timebase, rapid triggering can
capture a new waveform every 3 microseconds until the buffer is
full. The mask limit testing function helps to detect waveforms that
fail to meet your specifications.
Advanced triggers
As well as the standard range of triggers found on most
oscilloscopes, the PicoScope 4824 has a comprehensive set of
advanced triggers built in to help you capture the data you need.
These include pulse width, windowed, and dropout triggers to help
you find and capture your signal quickly.
High-end features as standard
Buying a PicoScope is not like making a purchase from other
oscilloscope companies, where optional extras considerably
increase the price. With our scopes, high-end features such as
resolution enhancement, mask limit testing, serial decoding,
advanced triggering, automatic measurements, math channels, XY
mode, segmented memory, and a signal generator are all included
in the price.
To protect your investment, both the PC software and firmware
inside the scope can be updated. Pico Technology have a long
history of providing new features for free through software
downloads. We deliver on our promises of future enhancements
year after year, unlike many other companies in the field. Users
of our products reward us by becoming lifelong customers and
frequently recommending us to their colleagues.
Mask limit testing
PicoScope allows you to draw a mask around any signal with
user-defined tolerances. This has been designed specifically for
production and debugging environments, enabling you to compare
signals. Simply capture a known good signal, draw a mask around
it, and then attach the system under test. PicoScope will capture
any intermittent glitches and can show a failure count and other
statistics in the Measurements window.
The numerical and graphical mask editors can be used separately or
in combination, allowing you to enter accurate mask specifications,
modify existing masks, and import and export masks as files.
Digital low-pass filtering
Each input channel has its own digital low-pass filter with
independently adjustable cut-off frequency from 1 Hz to the
full bandwidth of the scope. This enables you to reject noise on
selected channels while viewing high-bandwidth signals on the
others.
Custom probe settings
The custom probes menu allows you to correct for gain, attenuation,
offsets and nonlinearities of probes and transducers, or convert to
different measurement units. Definitions for standard Pico-supplied
probes are built in, but you can also create your own using linear
scaling or even an interpolated data table, and save them to disk
for later use.
