PicoScope-5244D-MSO

2 ch analog, 16 digital, 200 MHz, 1 GS/s,FlexRes

FlexRes^® 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 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 to 1 GS/s at 8 bits or the resolution to 16 bits at
62.5 MS/s.

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 result (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,
revealing every detail of the signal in a crystal-clear display. Sampling in parallel with multiple
ADCs and combining the output reduces noise and also both the integral and differential
nonlinearity, providing outstanding single shot dynamic performance without loss of bandwidth or
need of a repetitive signal

Using parallel mode, resolution is increased to 14 bits at 125 MS/s per channel (> 70 dB SFDR – see
diagram). 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 optimal resolution is used for the chosen settings.

FFT spectrum analyzer

The spectrum view plots amplitude against frequency and is ideal for finding noise, crosstalk or
distortion in signals. The spectrum analyzer in PicoScope is of the Fast Fourier Transform (FFT)
type which, unlike a traditional swept spectrum analyzer, can display the spectrum of a single, non-
repeating waveform.

A full range of settings gives you control over the number of spectrum bands (FFT bins), window
types, scaling (including log/log) and display modes (instantaneous, average, or peak-hold).

You can display multiple spectrum views alongside oscilloscope views of the same data. A
comprehensive set of automatic frequency-domain measurements can be added to the display, including
THD, THD+N, SNR, SINAD and IMD. A mask limit test can be applied to a spectrum and you can even use
the AWG and spectrum mode together to perform swept scalar network analysis.

Software Development Kit - write your own apps

The software development kit (SDK) allows you to write your own software and includes drivers for
Microsoft Windows, Apple Mac (OS X) and Linux (including Raspberry Pi and BeagleBone).

Example code shows how to interface to third-party software packages such as Microsoft Excel,
National Instruments LabVIEW and MathWorks MATLAB.

There is also an active community of PicoScope users who share code and applications on the Pico
forum and PicoApps section of the picotech.com web site. The Frequency Response Analyzer shown
opposite is one of the most popular 3rd party applications.

Mixed-signal

The PicoScope-5244D MSO models add 16 digital channels to the 2 analog channels, enabling you to
accurately time-correlate analog and digital channels. Digital channels may be grouped and
displayed as a bus, with each bus value displayed in hex, binary or decimal or as a level (for DAC
testing). You can set advanced triggers across both the analog and digital channels. The digital
inputs also bring extra power to the serial decoding options. You can decode serial data on all
analog and digital channels simultaneously, giving you up to 20 channels of data – for example
decoding multiple SPI, I²C, CAN bus, LIN bus and FlexRay signals all at the same time.
