– how we do it
Most digital oscilloscopes gain their high sampling rates by interleaving multiple 8-bit
ADCs. Despite careful design, the interleaving process introduces errors that always
make the dynamic performance worse than the performance of the individual ADC
cores.The FlexRes architecture employs multiple high-resolution ADCs at the input
channels in different time-interleaved and parallel combinations to optimize either
the sampling rate to 1 GS/s at 8 bits, the resolution to 16 bits at 62.5 MS/s, or other
combinations in between. Coupled with high signal-to-noise ratio ampliers and a
low-noise system architecture, FlexRes technology enables PicoScope 5000D Series
oscilloscopes to capture and display signals up to 200 MHz with a high sampling rate,
or lower-speed signals with 256 times more resolution than typical 8-bit oscilloscopes.
Resolution enhancement—a digital signal processing technique built into PicoScope—
can further increase the effective vertical resolution of the scope to 20 bits.
The PicoScope 6 software lets you choose between setting the resolution manually and
leaving the scope in “auto resolution” mode, where the optimal resolution is used for the
chosen settings.

High signal integrity
Here at Pico, we’re proud of the
dynamic performance of our
products. Careful front-end design
and shielding reduces noise,
crosstalk and harmonic distortion.
Over 25 years of high-resolution
oscilloscope design experience
leads to improved pulse response
and bandwidth atness.
Sensitivity at 1:1 zoom is an
impressive 2mV/div at the full
resolution of the oscilloscope. If you
need even more sensitivity then simply switch to high-resolution mode and zoom-in.
Combining 14-bit mode and zoom can provide 200µV/div sensitivity while still providing
more than 8bits usable resolution.
PicoSDK

- write your own apps
Our software development kit, PicoSDK, allows you to write your own software and
includes drivers for Windows, macOS and Linux. Example code supplied on our GitHub
organization page shows how to interface to third-party software packages such as
National Instruments LabVIEW and MathWorks MATLAB.
Amongst other features, the drivers support data streaming, a mode that captures
continuous gap-free data directly to your PC at rates of up to 125 MS/s, so you are not
limited by the size of your scope’s capture memory. Sampling rates in streaming mode
are subject to PC specications and application loading.
There is also an active
community of PicoScope
users who share both code
and whole applications on
our Test and Measurement
Forum and the PicoApps
section of the website.
The Frequency Response
Analyzer shown here is
one of the most popular of
these applications.
