WHAT DOES IT ALL MEAN?
The main specifications explained.
VERTICAL RESOLUTION
The number of dots in the waveform from top
to bottom. “12 bits” means 4,096 dots, which
is more detail than you can see on the screen all at once.
PicoScope stores the extra detail for when you zoom in.
BUFFER MEMORY
The number of dots in the waveform from left
to right. If you don’t have enough memory then
the waveform won’t show all the detail in the signal.
PicoScope has more than enough memory, so you can
zoom in thousands of times and still see a clear display
and spot intermittent glitches.
WAVEFORM BUFFER
A memory that collects your most recent
waveforms. If a waveform disappears off the
screen, you can look back through the waveform buffer
to find it.
TRIGGER
This ensures that the scope captures the
waveform at the right time and keeps it in a
stable position on the screen. PicoScope can set up
the trigger automatically, but if you want you can select
special trigger modes to catch unusual waveforms that
you might otherwise miss.
BANDWIDTH
For faster signals, more bandwidth gives a more
faithful reproduction of the signal shape on the
screen. PicoScope has enough bandwidth to display
CAN bus and FlexRay signals accurately.
SAMPLING RATE
Like bandwidth, this is more important for fast
signals. A high sampling rate ensures that you
catch the high-frequency details of the signal.
Errors and omissions excepted.
