PicoScope: power, portability and versatility
Pico Technology continues to push the limits of PC
oscilloscope design. For the first time in an oscilloscope,
Pico Technology have used reconfigurable ADCs to offer a
choice of 8-bit to 16-bit resolutions in a single product.
 Flexible resolution
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 new PicoScope 5000 series
scopes have a significantly different architecture in which
multiple high-resolution ADCs can be applied to the input
channels in different time-interleaved and parallel
combinations to boost either the sampling rate or the
resolution.
In time-interleaved mode, the ADCs are
interleaved to provide 1 GS/s at 8 bits (see diagram).
Interleaving reduces the performance of the ADCs, but the
resulting (60 dB SFDR) is still much better than
oscilloscopes that interleave 8-bit ADCs. This mode can also
provide 500 MS/s at 12 bits resolution.
In parallel mode, multiple ADCs are sampled in phase on each
channel to increase the resolution and dynamic performance
(see diagram). Sampling in parallel with multiple ADCs and
combining the output reduces noise and also both the
integral and differential nonlinearity.
Using
parallel mode, resolution is increased to 14 bits at 125
MS/s per channel (>70 dB SFDR). If only two channels are
required then resolution can be increased to 15 bits, and in
single-channel mode all the ADCs are combined to give a 16
bit mode at 62.5 MS/s. The software gives the choice of
selecting the resolution or leaving the scope in “auto
resolution” mode where the optimum resolution is used for
the chosen settings.
High
signal integrity
Most oscilloscopes are built
down to a price; ours are built up to a specification.
Careful front-end design and shielding reduces noise,
crosstalk and harmonic distortion. Over 20 years of high
resolution oscilloscope design experience leads to improved
pulse response and bandwidth flatness.
We are proud
of the dynamic performance of our products and publish these
specifications in detail. The result is simple: when you
probe a circuit, you can trust in the waveform you see on
the screen.
Portability
Pico Technology oscilloscopes are small, light and
portable. In 2-channel mode the 5000 series scopes can be
powered from USB only, making them ideal for the engineer on
the move. The external power supply is only needed when
operating more than 2 channels. The 5000 series
oscilloscopes are suitable for field use in many
applications, such as design, research, test, education,
service and repair.
